About

I'm a senior full-stack engineer with 16+ years of commercial experience. I started at SimbirSoft straight after a non-IT degree, ramped through 30+ projects across very different stacks, and have spent most of the last decade working remotely with clients in the US, Germany, Switzerland and elsewhere.

The last 6.5 years I was at Vereign (Switzerland) building a Zero-Trust authentic-communication platform — primarily on frontend and mobile: cryptographically verifiable email, self-sovereign identity on Credo-TS, IPFS-based storage, mobile apps shipped to the App Store and Google Play, and an Outlook plugin distributed via Microsoft AppSource.

After Vereign I took a year of focused product work — shipping ~20 small experiments and going deep on the modern AI stack (Zencoder + Cursor as primary IDE plugins, plus Claude, ChatGPT, Grok, Perplexity, DeepSeek for product features and research). Now looking to bring this product mindset back into a focused team.

How I work

  • End-to-end ownership
    I can take a product from idea to production solo — frontend, backend, mobile, infra and release.
  • Comfortable in unknown stacks
    At SimbirSoft I was the engineer rotated onto troubled projects — ramp on a new stack within weeks and stabilize delivery.
  • AI-assisted, not AI-replaced
    I use Zencoder + Cursor and multi-LLM workflows daily to ship faster, with careful review of every output.
  • Direct communication
    No agency, no middlemen — you talk to the engineer who writes the code.
