I'm a Full Stack Developer focused on building real, production-ready web applications from scratch.
I work mainly with React, Next.js and Node.js, and I enjoy turning ideas into functional products — from database design and APIs to UI and deployment.
Currently, I'm:
- 🚀 Building and iterating on SaaS products
- 🧠 Improving my backend architecture and database design
- 💼 Open to Junior roles or projects where I can grow while delivering real value
