About me
Full-stack developer specialized in secure, scalable web and PWA applications. I’ve built products from the ground up — including a clinical management suite with role-based access control (RBAC), encrypted patient data, and offline-first architecture, plus a real-time inventory management platform.
I work with React, TypeScript, Node.js, and Firebase/Supabase, focusing on clean architecture and multi-tenant systems. Whether you need a new feature, a security fix, or a full module built from scratch, I deliver clear communication and well-documented code.
Let’s build something solid together.
