Senior Full Stack Developer

I build reliable, fast and well-designed web products end to end — from TypeScript front ends people enjoy using to distributed back ends that stay calm under load. Over twelve years I have shipped SaaS platforms, real-time dashboards and payment-grade APIs, led small teams through rewrites without downtime, and kept a steady focus on clean architecture, observability and developer experience.
