Implementing the Low Stock Alert System – Reflections from Sprint-3

During Sprint-3, I focused on building and refining a critical feature for our inventory management backend: a low stock alert system. Alongside this, I dedicated time to improving project documentation and maintaining clarity in code contributions. This sprint challenged both my technical implementation skills and my ability to communicate system behavior effectively for team collaboration.

What Was Implemented

The low stock alert system was designed to run once daily at 10 AM on weekdays, checking if any products in categorized_database.json had dropped below their respective minimum stock threshold. If a product was low, an email alert was automatically triggered using nodemailer and Gmail’s SMTP service.

To ensure this didn’t overload the system, I used a time-gated setInterval() inside index.js that only allowed email triggers if the day was between Monday and Friday and the hour equaled 10. The function checkAndSendLowStockAlert() in stockAlert.js handled the core logic and email composition.

Documentation Work

I also spent significant time documenting:

  • Purpose and responsibilities of the new stockAlert.js module.
  • Integration lines in stockAlert.js showing how and when the alert system executes.
  • Comments in code explaining each logic block.
  • A issue description called Low stock product alert covering everything from cron-like scheduling logic to pending Gmail credentials that require updates for the system to function securely.

GitLab Activity Highlights

What Worked Well

  • Modularization: Separating the alert system logic from index.js into its own file (stockAlert.js) helped maintain clean code structure and made debugging much easier.
  • Scheduled execution: Implementing a weekday/time condition made the feature realistic for workplace use and prevented unnecessary system loads.
  • Collaborative Documentation: Keeping a running commentary in GitLab merge requests helped the team understand changes quickly and facilitated smooth peer reviews.

What Didn’t Work Well

  • Gmail integration required an app password and correct permissions. The first few test runs failed due to missing or incorrect credentials.
  • Initial testing limitations: Since the alert only triggers once per day at 10 AM, simulating scenarios for rapid testing was a challenge.
  • Delayed implementation of logging: Early iterations lacked logs or fallbacks, making failures harder to trace.
  • After talking to professor Karl, he wanted to the server to handle this, so an issue was created so it alert can be server-handled task.

What Could Be Improved as a Team

  • Create a shared .env or config file that can be used across modules instead of hardcoding emails or thresholds.
  • Develop a simulation mode to test time-bound functions instantly, especially for scheduled jobs.
  • Review and testing sessions could be more frequent and planned earlier in the sprint.

What Could Be Improved as an Individual

  • I should’ve created mock data and test harnesses sooner to simulate alerts without waiting for specific days or times.
  • Next time, I’ll also write unit tests for alert logic to ensure that key conditions are evaluated correctly.
  • I should’ve been quicker to document issues with the Gmail setup and create a checklist for anyone running the alert system in another environment.

Apprenticeship Pattern: “Breakable Toys” (Chapter 3)

Summary: The “Breakable Toys” pattern encourages developers to build small, personal projects that simulate real-world systems, allowing them to make mistakes safely and learn without real consequences.

Why I Chose It: This pattern resonated deeply with my experience during the sprint. The low stock alert feature was like a small “toy system” that had the same structure as production-level alert systems (scheduled jobs, email APIs, condition checks) but existed in a controlled environment.

Relevance: During this sprint, I often wished for a sandboxed copy of our inventory system just to run quick iterations. The constraints of the main codebase slowed experimentation. Had I consciously embraced the “Breakable Toys” mindset earlier, I could have built a parallel mini-system that isolated alert logic and Gmail testing—speeding up development and reducing risk.

How It Would’ve Helped: Reading this pattern in advance would have prompted me to:

  • Clone and strip down the inventory codebase into a test script.
  • Avoid introducing bugs into the primary system.
  • Feel more confident experimenting with cron-style scheduling and async email logic.

Apprenticeship Pattern: “Expose Your Ignorance”

Summary of the Pattern

The “Expose Your Ignorance” pattern from the Apprenticeship Patterns book emphasizes acknowledging one’s knowledge gaps and actively seeking to learn. It encourages transparency about what you don’t know while making efforts to bridge those gaps.

Why This Pattern Was Selected

During this sprint, I faced challenges with API automation and data cleaning that slowed my progress. If I had openly acknowledged my lack of expertise in automation sooner, I could have sought help from peers or external resources earlier in the sprint. This pattern aligns with my experience because it highlights the importance of being upfront about knowledge gaps and taking proactive steps to fill them.

How This Pattern Would Have Changed My Behavior

Had I followed this pattern earlier in the sprint:

  • I would have sought advice from team members or forums on API automation instead of spending excessive time trying to figure it out alone.
  • I would have explored existing libraries or tools for handling JSON parsing issues more efficiently instead of resorting to manual cleaning.

Conclusion

This sprint provided valuable lessons in data handling, API limitations, and the importance of seeking help when needed. Moving forward, I plan to improve communication within the team, allocate more time to the project, and be more proactive in addressing technical challenges. Applying the “Expose Your Ignorance” pattern will help me become a more effective contributor in future sprints.

The beginning of a Journey of a Software Craftsman: Reflections on Chapter 1 of Apprenticeship Patterns

The path to becoming a skilled software developer is not just about learning programming languages or mastering frameworks—it’s about embracing a mindset of continuous learning, humility, and craftsmanship. Chapter 1 of Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman by Dave Hoover and Adewale Oshineye sets the foundation for this philosophy, introducing readers to the idea of software development as a lifelong journey of growth.

One of the most compelling aspects of this chapter is its focus on the concept of apprenticeship in software development. Unlike traditional education or even structured corporate training, an apprenticeship mindset encourages developers to seek knowledge actively, engage with mentors, and build real-world experience through deliberate practice. The book compares software craftsmanship to traditional guilds, where newcomers learn by doing, gradually refining their skills under the guidance of experienced practitioners.

The emphasis on deliberate practice particularly resonated with me. It’s easy to fall into the trap of writing code every day and assuming that practice alone leads to mastery. However, the book suggests that true improvement comes from purposeful and reflective practice—analyzing mistakes, challenging oneself, and continuously pushing the boundaries of one’s abilities. This idea shifted my perspective on how I approach learning new technologies and refining my existing skills.

Before reading this chapter, I viewed my professional growth in software development as something that happens naturally over time—an accumulation of experience gained from projects and exposure to different technologies. However, Apprenticeship Patterns made me realize that growth must be intentional. It’s not enough to just work on projects; I need to actively seek out challenges, solicit feedback, and set concrete learning goals to accelerate my progress.

Another takeaway that impacted my mindset is the importance of humility. The book stresses that being a software craftsman requires accepting that there will always be more to learn. I found this particularly valuable because it aligns with the idea of the beginner’s mind—approaching every problem, regardless of experience, with curiosity and openness rather than arrogance.

P

While I found the chapter insightful, one point that I questioned was the romanticization of apprenticeship as a primary learning model. While mentorship and hands-on learning are invaluable, not everyone has access to experienced developers willing to guide them. In today’s fast-paced software industry, many developers are self-taught through online courses, coding boot camps, and open-source contributions. While the book acknowledges that different learning paths exist, I think it could have placed more emphasis on alternative ways to develop craftsmanship outside of the traditional mentor-apprentice model.

Which Chapters Seem Most Relevant?

From a quick glance at the table of contents, the chapters that seem most relevan that caught me:

  • This seems crucial for maintaining motivation and engagement in the field. Passion is what drives deep learning.
  • I’m interested in how the book suggests balancing learning new, complex topics while also reinforcing foundational skills.
  • This chapter likely discusses the tension between personal growth as a developer versus career advancement, a topic that resonates deeply with me as I navigate my own path.

Chapter 1 of Apprenticeship Patterns offers an inspiring and thought-provoking perspective on how to approach software development as a lifelong craft. It reinforced my belief that learning should be intentional and reflective, and it pushed me to think about how I can structure my growth more effectively. While I don’t entirely agree with every aspect of the apprenticeship model, I appreciate the book’s emphasis on continuous improvement, humility, and the importance of deliberate practice.

For aspiring and experienced developers alike, this book serves as a guide to not just writing better code, but becoming a better craftsman in the art of software development.

As a beginner, I was looking for a resource that could demystify design patterns without overwhelming me with technical jargon, and this article did exactly that.

Personal Reflection and Key Takeaways

The material was enlightening, especially in how it framed design patterns as reusable solutions to software design issues. Before reading the article, my understanding of patterns like Singleton or Factory was limited to theoretical concepts, but the examples provided helped me visualize their practical applications. One major lesson I took from this article is the importance of the Singleton pattern, which ensures that a class has only one instance and provides a global point of access to that instance. This concept is essential in areas like database connections, where having multiple instances could lead to conflicts.

Additionally, learning about the Factory pattern—a creational pattern that allows for the creation of objects without specifying the exact class—opened my eyes to how flexibility and scalability are achievable in code. This pattern is especially helpful when dealing with large projects where new object types might frequently need to be added.

The article not only strengthened my grasp of object-oriented principles but also inspired me to think more critically about how I structure my code. It shifted my perspective from merely getting the code to work, to considering how to design it efficiently for future use and maintenance. I now see design patterns as a roadmap to writing better, more scalable code.

Future Application of Design Patterns

Moving forward, I plan to incorporate these design patterns into my coding work practices, particularly in my Java projects. The Singleton pattern will be useful in managing system-wide resources, while the Factory pattern will aid in developing modular code that can easily evolve.

Understanding Design Smells and Technical Debt: A Beginner’s Guide

In the world of computer science, especially for those new to programming, concepts like design smells and technical debt can seem daunting. However, grasping these ideas is crucial for building sustainable software. Design smells are indicators of potential problems in your code, such as overly complex structures or poor naming conventions. Technical debt, on the other hand, refers to the compromises made during the development process that can lead to greater issues down the line, akin to borrowing money that needs to be paid back later.

I recently came across the article “Understanding Technical Debt” by Tom Smith on Medium. This piece breaks down these concepts in an approachable manner, making them easier to understand for beginners. Smith discusses common design smells, such as “Long Method” and “Feature Envy,” and explains how they can accumulate into technical debt if ignored.

I chose this article because I believe it provides a solid foundation for understanding these concepts without overwhelming beginners with jargon. As I embark on my journey in computer science, I find it essential to learn about the long-term implications of my coding decisions. Smith’s article highlights the importance of recognizing design smells early on, which resonated with me as I often focus on getting things done rather than considering the quality of my code.

What I learned from the article is that design smells serve as early warning signs. For example, if a method is too long or complex, it may indicate that it’s doing too much and should be broken down into smaller, more manageable pieces. This insight has made me reflect on my past coding experiences, particularly a group project where we rushed to implement features without thoroughly reviewing our code. The result was a project that became difficult to manage and understand. I realized that by overlooking design smells, we inadvertently added technical debt to our project.

Moving forward, I plan to apply this knowledge in my coding practice by adopting a more mindful approach. I want to prioritize code quality and regularly check for design smells as part of my workflow. Implementing practices like peer code reviews and refactoring sessions will help ensure that my code remains clean and maintainable. I believe this proactive approach will not only enhance my skills but also contribute to a more positive team environment where everyone is encouraged to uphold coding standards.

In conclusion, understanding design smells and technical debt is vital for anyone starting in computer science. By paying attention to these indicators, we can write better, more maintainable code. I highly recommend reading Tom Smith’s article for a beginner-friendly introduction to these essential concepts.

Welcome to Software Construction, Des & Architecture blog.

In this blog will be talking about the aspects of software construction, design and architecture aspects.

When building software, three important aspects to consider are construction, design, and architecture. Construction is about writing the actual code that makes the software work. It’s like putting together the pieces of a puzzle to ensure everything fits and functions correctly. Design is like planning the layout of a house before you start building. It involves figuring out how different parts of the software will work together, making sure everything is organized and easy to use.

Architecture is the big-picture plan for the software, similar to designing the overall structure of a building. It decides how all the different pieces fit together and interact with each other. Good architecture ensures the software can handle changes and grow over time without falling apart. By focusing on construction, design, and architecture, developers can create software that’s not only functional but also easy to maintain and expand in the future.
