About Me


Backend Developer • Problem Solver • Tech Enthusiast


Hey, I'm Harison — a Python backend developer who enjoys building things that make life easier. I’ve worked with frameworks like Django and Flask to create everything from REST APIs and blog platforms to quiz systems and weather apps.

I care a lot about writing clean, secure code and making sure what I build actually solves real problems. I’m also comfortable integrating third-party APIs, working with databases, and deploying projects that work well online.

Outside of coding, I enjoy learning new tech, contributing to side projects, and keeping up with backend trends. Let’s build something cool!
