Hi! I'm Kelvin, a full-stack developer who helps businesses build and ship web and mobile applications that actually work in production, not just in a demo.
I specialize in building with React and Next.js on the frontend, and PHP, Node.js, and Python (FastAPI) on the backend, with PostgreSQL for data architecture that holds up as things scale. I design and build REST APIs, handle authentication and authorization, enforce data validation with tools like Pydantic, and integrate third-party services like payment gateways and cloud storage when a project calls for it.
On the mobile side, I build cross-platform apps with React Native and Flutter, handling everything from UI and state management to authentication, backend integration, and device-level features.
I care about more than just making something run. Database schema design, API architecture, and system reliability all factor into how I build, so what launches doesn't need to be rebuilt in six months.
I'm also expanding into AI automation, building workflows that connect APIs and language models to cut down on repetitive manual work.
If you're looking for someone technical, reliable, and easy to work with, I'd love to help bring your next project to life.
