About

Who I am

I'm a BSIT student at Colegio de Kidapawan with a deep focus on backend and full-stack development.

My strongest domain is backend API development with ASP.NET Core, combined with cloud deployment on Azure and mobile apps built with React Native and Expo Go.

Currently open to freelance commissions, part-time roles, and collaborative projects. Best for school systems, mobile apps, and backend infrastructure.

How I Work

Development
principles

01
Clean Architecture
Layers of concern separated. Business logic isolated from infrastructure. Systems that are easy to test, change, and scale without fear.
→
02
SOLID Principles
Single responsibility, open/closed, Liskov substitution, interface segregation, dependency inversion — written into every class I ship.
→
03
Maintainable Code
Code is read far more often than it's written. Clarity, naming, and structure are features — not afterthoughts or polish left for later.
→
04
API-First Development
Design the contract before building. Decouple frontend from backend. Enable multiple clients — mobile, web, third-party — from a single truth.
