Senior Full-Stack Engineer & Engineering Manager

I am a Software Engineer with a deep passion for building well-crafted, meaningful software that positively impacts people’s lives. While I have extensive experience in mobile development (React Native), my expertise spans the entire stack, including frontend and backend development.

I thrive on taking responsibility—whether it’s leading teams, driving technical decisions, or ensuring software quality. For me, engineering is more than just writing code; it’s about craftsmanship, mastery, and continuous learning.

Above all, I am driven by purpose and human connection. I believe that the most valuable software isn’t just functional—it solves real problems, brings people together, and enhances lives. Whether collaborating with teams or building impactful products, my goal is always to create technology that truly matters.
