    Hi there! I'm a full-stack developer with 6+ years of experience delivering robust and scalable web applications. My core stack is React/Next.js, Node.js, and PostgreSQL, and I've also worked with Django and Ruby on Rails. From dynamic startup teams to large organizations like RedBull and the European Commission, I’ve helped turn ideas into working products — quickly and cleanly. I care about writing clear, maintainable code, and I believe tests should support development, not slow it down. I’ve worked both independently and as part of agile teams, and I’m comfortable jumping into projects at any stage — from MVPs to mature platforms. Beyond client work, I’ve built and maintained a SaaS app that now serves thousands of users, which reflects how I approach software: with ownership, long-term thinking, and a love for the craft. Whether you need someone to support your team or take charge of a standalone project, I bring technical depth, a collaborative spirit, and a focus on delivering real value. Let’s build something great together.
