I build robust, scalable web applications with clean architecture and thoughtful user experiences. Focused on delivering real business value through code.

About Me

Building software that matters

I'm a Full-Stack Developer with a passion for building applications that solve real problems. My journey started with curiosity about how things work on the web, and has evolved into a career focused on creating robust, scalable solutions.

I specialize in the JavaScript/TypeScript ecosystem, working across the entire stack from React frontends to Node.js backends. What drives me is not just writing code, but understanding the business context and delivering software that creates measurable impact.

When approaching a project, I think in systems: How will this scale? How will the next developer understand this? What happens when requirements change? This mindset helps me build software that stands the test of time.

Scalable Solutions

User-Focused

Every technical decision is guided by real user needs and business impact.
