About me

Building software.
Delivering impact.

I'm a software engineer focused on building scalable web applications and digital products that combine strong architecture with practical business value.

Over the last 13+ years, I've worked on SaaS platforms, enterprise systems, e-commerce products, and public sector applications — from backend architecture and APIs to frontend development and technical leadership.

I enjoy designing maintainable systems, solving complex technical challenges, and helping teams deliver products that can grow long-term.
