I help product teams and founders ship complete web products end to end—frontend through backend—plus the AI and voice features layered on top.

Senior engineer, 15+ years: Go for high-performance backends, TypeScript / React / Next.js for the frontend and product layer, with Ruby on Rails and Python where they fit. I've built enterprise platforms from the ground up (a retail-media campaign-management platform serving 200+ brands), engineered C++/Go SDKs deployed across connected-car fleets at HERE Technologies (BMW, Audi, VW, Porsche), and delivered B2B vendor and operations tooling at Deliveroo and Delivery Hero.

Recent focus is applied AI in production: at DialHard (a live VoIP product on Rails), real-time speech-to-text pipelines and AI-powered inbound/outbound calling with LLM voice assistants—and I can stand up voice agents and apps from scratch (WebRTC/VoIP + AI). Alongside it: agentic pipelines on MCP and a design-system generator that turns a plain-language brief into production-ready tokens and components.

What you get:

- Whole web products, idea to ship—frontend (React/Next.js), backend, deploy

- Backends in Go—also Rails and Python—event-sourced services, GraphQL/REST APIs, microservices on AWS/GCP & Kubernetes

- Voice & real-time—WebRTC/VoIP, STT, LLM voice agents; prototype to working MVP

- LLM / agentic features—streaming, tool-use, retrieval, cost-aware model routing

- An autonomous operator who ships weekly and works directly with founders

Typical engagements: standing up a new product or voice app from zero, scaling or rescuing an existing codebase, or adding AI to a live product. Available remote, Berlin-based.
