About Me

I'm a Back-End Developer passionate about building clean, secure, and scalable systems. For the past four years, I've been developing software — from small local projects to ERP systems and international platforms. I began my journey with Python, and today, I build with Node.js and TypeScript, crafting systems that not only work — but are thoughtfully designed. I believe in the philosophy of simplicity in code: a good piece of software is one where the developer struggles less, and the user never feels the complexity behind it.
