How I got here

It started with curiosity about how websites work. That turned into WordPress sites for local businesses, then full-stack apps with React, Node.js and MongoDB for clients on Fiverr and Upwork.

I care about clean, maintainable code and interfaces that are easy to use. Whether it's a backend API or a landing page, every project gets the same attention to detail.

Outside client work I explore new frameworks, contribute to open source and write about what I learn on the blog.
