Curious about me? Here you have it:

I'm a passionate Full Stack Developer specialized in Front-End development with a strong focus on creating exceptional digital experiences. I care deeply about user experience, pixel-perfect design, and writing clean, readable, highly performant code.

My journey as a developer began back in 2013, and since then I've continued to grow and evolve, taking on new challenges and learning the latest technologies along the way. Over 6+ years working professionally, I've delivered 15+ web and mobile projects across industries β€” from healthcare dashboards and e-commerce platforms to 3D visualization tools and cross-platform mobile apps.

I am very much a progressive thinker and enjoy working on products end to end, from ideation all the way to production deployment. I thrive in remote, English-speaking teams and I'm comfortable owning features from design handoff to ship.

When I'm not in full-on developer mode, you can find me exploring new tech, tinkering with local LLM deployments, or contributing to internal tooling projects.

Finally, some quick bits about me:
