Available for new work

Hire me

I design AI agent systems and the platforms they run on. I also write the code and help ship it.

If I think your plan will not work, I say so.

Why hire me

  • You work with me. No account manager and no handoff to a junior developer. I write the code.
  • 15 years in production. High-traffic classifieds at OLX, platform tooling at AnyDesk, cloud infrastructure at GFE Media.
  • I build agent systems, not only advise on them. Multi-tenant agents, tool surfaces, memory, cost limits.
  • Fixed prices. Each service has a starting price. You get a fixed quote before work starts. I do not bill by the hour.
  • CET hours. Full overlap with the EU. Morning overlap with the US East Coast.
  • I say no. If I am not the right person, I tell you, and where I can, I name someone who is.

Selected work

  • Client project

    AI relationship management platform

    • Owned the architecture: NestJS services, PostgreSQL and Neo4j data models, a React Native client and the conversational AI layer.
    • Designed multi-tenant agents with per-tenant isolation, custom tools, persistent memory and state sync in PostgreSQL. Agents start on demand and suspend when idle, so cost per agent stays bounded.

  • Client project

    E-commerce marketplace

    • Set up a Turborepo monorepo for backend services, shared packages and frontends, and defined the contracts other developers worked against.
    • Designed services around a GraphQL monolith: Node.js/TypeScript services in Express and Hono, with Hasura actions that enforce business logic at the boundary.

  • AnyDesk GmbH

    Platform operations tooling

    • Built the internal web hub for platform operations with React, Next.js, TypeScript and PostgreSQL.
    • Connected Node.js services to Keycloak for authentication, and added localization with i18next.
