Growing with Precision: Enhancing LodgingFlow with Pagination

Week 5 was a continuation of expanding the LodgingFlow backend, but with a new focus on improving data retrieval efficiency. Building on the secure foundation from previous weeks, I added additional functions and database collections while implementing pagination on all GET endpoints to handle larger datasets gracefully.

Structured Expansion
Each new function introduced supported the core operational needs of LodgingFlow, with authentication and encryption integrated as before. The database collections grew to accommodate more granular data, all designed to fit the existing schema securely.

Pagination for Performance
Adding pagination was crucial for scaling. I refactored every GET endpoint to accept page and limit parameters, allowing clients to request manageable chunks of data instead of loading entire collections at once. This not only improved performance but also optimized network and client resource usage.

I tested these enhancements thoroughly in Postman, simulating different page requests and ensuring consistent behavior across all paginated endpoints. Proper HTTP status codes and response metadata, such as total count and current page, were included to aid frontend integration.

Reflection: Building Scalable APIs
Week 5 underscored the importance of anticipating growth—not just in features but in data volume. Pagination is a simple but powerful tool for ensuring that an API remains responsive and user-friendly as usage scales.

By combining secure new functions with thoughtful data management, I contributed to making LodgingFlow a backend system ready for real-world demands.

Completed Highlights

  • Added new functions and collections to the LodgingFlow backend

  • Integrated pagination on all GET endpoints with page and limit parameters

  • Maintained Firebase authentication and AES encryption on all routes

  • Tested pagination and data retrieval scenarios in Postman

  • Improved API response structure with metadata for client-side handling

Week 2: Refactoring and Cloud Integration

  June 16–20, 2025 Christian M. Lagarde – 3rd Year Computer Science Student Bicol University  From Local Logic to Cloud Literacy: The AWS Transition The second week of my internship at StraStan Solutions Corp. brought with it a shift in both environment and expectation. Where the first week had grounded me in local backend development using Express.js and Node, this week pulled me into something far larger— the cloud . It started with an AWS setup tutorial that would lay the foundation for everything we were about to build. The transition from developing purely on my machine to understanding infrastructure-as-code was disorienting at first. AWS CDK was no longer just a buzzword—it was the bridge between code and scalable deployment. Node.js Conversion: Building on Familiar Ground While I explored the AWS ecosystem, I was also tasked with converting the Project Task Manager API —originally built in Week 1 using Express.js—into a more modular and cloud-ready Node.js vers...

Week 1: Orientation and Onboarding

  June 9–13, 2025 Christian M. Lagarde – 3rd Year Computer Science Student Bicol University The Digital Threshold Monday marked the start of a new chapter—not just another academic requirement, but the real-world application of everything I’d been studying for the past three years. As I joined the virtual orientation hosted by Mr. Mohammad Ali Fereydouni, our OJT manager at StraStan Solutions Corp., I was acutely aware of the transition that was taking place. We weren’t just students anymore. We were contributors. The meeting was brisk and purposeful. Mr. Fereydouni introduced StraStan not just as a company, but as a training ground where we would be treated like junior developers, not observers. Expectations were made clear. The workload would be real. And we would be held accountable. I welcomed the challenge. Infrastructure of Independence By Tuesday, we were setting up access to tools and resources. The remote desktop configuration, Chrome work profile setup, and environ...

Week 7: Frontend Fixes and Collaborative Admin Panel Design

  OJT Weekly Narrative – Week 7 July 21 – July 25, 2025 Christian M. Lagarde – 3rd Year Computer Science Student Enhancing User Experience: Frontend Improvements and Admin Panel Creation Week 7 was dedicated to improving the Jewelry E-Commerce project’s frontend, focusing on both user-facing features and administrative tools. I concentrated on fixing issues in the products section and refining the add-to-cart functionality to ensure a smoother shopping experience. Collaborating closely with a team member, I also designed and developed the admin panel frontend , laying out an intuitive interface for product and order management. This panel will serve as the control center for admins to efficiently oversee store operations. Through these tasks, I deepened my understanding of frontend frameworks and strengthened my teamwork skills, balancing design considerations with functional requirements. Reflection: Frontend Functionality Meets User and Admin Needs This week reminded m...
