About me

Built for operators, not just demos

I am a Senior Full Stack Developer with 10+ years shipping web platforms, e-commerce, CRM, and automation for international and remote teams.

My recent work focuses on storefronts that convert, marketplaces that move money safely, and CRM modules sales teams actually use — React, Next.js, Node.js, Python, and modern data layers.

Clients hire me when they need more than a template: clear UX, secure integrations, CMS-friendly content models, and documentation so the business stays autonomous.
