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.
