About Me
Turning real business requirements into reliable and maintainable software
Full Stack Software Developer | Web Developer | AI-Assisted Development
I'm an Information Technology graduate and full-stack software developer focused on building and maintaining practical web applications, business systems, backend services, databases, and integrations. My experience spans POS solutions, inventory workflows, relational databases, REST APIs, real-time functionality, and modern frontend interfaces.
I design, build, and deploy full-stack software solutions tailored to real-world business and operational requirements—from retail cashier terminals and inventory ledger systems to municipal management platforms. I leverage an AI-assisted development workflow for efficient analysis, implementation, and refactoring while ensuring all code is thoroughly tested, validated, and production-ready.

How I Build
From requirements to maintenance, with testing built into every stage
Requirements
Understand the real workflow with clients and staff, then define scope, roles, and expected outcomes.
Design
Plan the database schema, API structure, and interface layouts before writing production code.
Build
Develop frontend, backend, and database features in small increments, tracked with Git.
Testing & Quality Assurance
Every feature is verified before release, not only at the end of the project.
- Functional testing: walk through real workflows such as checkout, stock updates, and reports.
- API testing: verify endpoints, responses, authentication, and error handling.
- Edge cases & validation: invalid input, duplicates, empty states, and permission checks.
- Regression checks: re-test existing features after each change.
- Cross-device checks: confirm responsive behavior on desktop, tablet, and mobile.
- User acceptance: validate with real users in the actual environment.
Bugs are logged, fixed, and re-tested before the next stage.
Deployment
Release to Cloudflare Pages/Workers, Vercel, Render, or GitHub Pages, followed by a smoke test on the live site.
Maintenance
Fix issues, apply improvements, and update features based on user feedback after launch.
