About

Full stack engineer with 14 years shipping products to real users across Go, TypeScript, React, React Native, GraphQL, gRPC, and Postgres, currently delivering LLM-powered systems to production at Spaceship/eToro.

I thrive at the customer-facing end of engineering—turning open scopes into shipped software, embedding with product and platform teams across Europe and APAC, and building internal AI platforms (e.g., an LLM wiki knowledge base and MCP interfaces for market data) with a code-quality mindset: specs, review, and tests.
