About

From idea to production,
across the full stack.

Software Developer with 10+ years of experience building products from idea to production across web and mobile. My work spans frontend systems, backend services, real-time applications, native mobile integrations, and product architecture.

I focus on turning complex problems into reliable, production-ready systems. Experienced leading implementations, modernizing codebases, and delivering software across consumer apps, events, fintech, health, education, government, e-commerce, and SaaS environments.

Known for adapting quickly to the needs of each product and taking ownership across the full development lifecycle.
