My Résumé

I’m a web developer who loves turning ideas into digital products that people actually enjoy using. Whether it’s a simple website or a full online system, I focus on creating experiences that are smooth, reliable, and easy to use.

I enjoy solving problems and finding practical solutions that make life easier for both businesses and users. Every project is a chance for me to learn something new and bring fresh ideas into the work I do.

Beyond building websites, I care about making each project meaningful and impactful. My goal is always to deliver something that not only works well but also feels intuitive and enjoyable for the people who use it.

Coffipaste

Full-stack Developer, 2025-present

I’ve been working on a fully dynamic inventory and sales management system that goes beyond a standard POS. It helps businesses track products, manage sales, and streamline daily operations in real time through a clean and intuitive interface. To bring it to life, I’m using Next.js for a fast and scalable frontend, Drizzle ORM and tRPC for a type-safe and efficient backend, and Tailwind CSS with Shadcn UI for a polished, modern design. The app is deployed on a VPS and managed with Dokploy, giving me flexibility, reliability, and room to scale. Along the way, I’ve integrated many other tools and libraries to make the system as dynamic and feature-rich as possible.

HTLS Marketing

Full-stack Developer, 2025 (2 months)

I also built a booking and inventory management system that streamlined reservations while keeping product stock and availability in sync. Using the same stack — Next.js, tRPC, Tailwind CSS, Shadcn UI, deployment on a VPS with Dokploy, and Prisma on the backend (with plans to migrate to Drizzle ORM) — the app provided both customers and staff with a smooth experience. It allowed users to book seamlessly while giving administrators full visibility and control over inventory, ensuring operations ran efficiently without overbooking or stock issues.

Dalawinon Farmers

Full-stack Developer, 2025 (2 months)

I developed a sales and inventory management system for Dalawinon Farmers’ RPC and Agri-Supply, which helped them track their agricultural products, manage sales, and organize stock in one reliable platform. The backend was built with Prisma, though I had plans to migrate it to Drizzle ORM for better scalability and maintainability. The rest of the stack included Next.js, tRPC, Tailwind CSS, Shadcn UI, and deployment on a VPS managed with Dokploy. This setup made the app dynamic, user-friendly, and capable of supporting the cooperative’s growing operations.

Davao Doctors College

IT Staff/Full-stack Developer, 2024-2025 (3 months)

IT Ticketing System:

While working as an IT Staff at Davao Doctors College, I developed an IT Ticketing System to streamline the management of technical support requests across all departments. The system improved issue tracking, response efficiency, and overall IT support operations by providing a structured workflow for ticket handling.

MIS Asset Manager:

In order to effectively track and monitor IT assets, inventory, logbooks, and other crucial resources, I also created MIS Asset Manager. By guaranteeing accurate record-keeping and promoting better decision-making for the allocation of IT resources, this solution enhanced asset management.

The systems was built using Next.js with Tailwind CSS for the frontend, Prisma as the ORM, and SQL as the database. It was deployed on a physical server within the office to ensure secure and reliable access for internal use. In addition to development, I occasionally assisted the IT team in troubleshooting system-related issues to ensure smooth operation and minimize downtime.

ProWESS

Mobile Developer, 2023-2024 (1 year)

I built the mobile application ProWESS specifically for the Province of Davao del Sur as part of my internship and capstone project. The technology helps beneficiaries find work and manage their scholarships more efficiently by acting as a job matching prediction tool, monitoring dashboard, and scholarship registry.

The application was built using Flutter for the frontend and PHP for the backend, with deployment managed through Hostinger. In addition to development, I ensured system stability and usability by addressing technical issues and optimizing performance to meet the project's objectives.
