I’m a Full Stack Developer with strong experience in TypeScript, Node.js, NestJS, Next.js, and SQL databases. I’ve built and maintained real business systems, mainly focused on backend architecture, APIs, integrations, and web applications. What stands out about me is that I care not only about making things work, but making them clean, scalable, and easy to maintain. I learn fast, communicate well, and I’m comfortable working from planning to delivery.
