As a full stack developer — and honestly, as a Formula 1 fan too — I naturally care about speed, precision, clean teamwork, fast iteration, and performance under pressure.

I’m a full stack developer, web developer, and app developer with hands-on experience building web applications, dashboards, AI tools, internal systems, mobile apps, websites, business platforms, and scalable digital products for startups, agencies, and growing companies.
