About
My development journey started with Java and the Spring Boot ecosystem, where I spent years building robust enterprise applications and high-performance APIs.
Over time, I expanded my expertise into modern web development — React, TypeScript, Astro — while keeping the backend rigor that makes a real difference in fullstack architectures.
The rise of generative AI marked a turning point in my career. I dove into the world of LLMs, prompt engineering, and AI agents, convinced that the synergy between traditional development and AI unlocks unprecedented possibilities.
Today, I position myself as an AI-augmented developer: I design solutions where code and artificial intelligence work together to create smarter, faster, and more impactful products.
