AI engineering across the full stack.
Over the past year I've focused on AI engineering end to end — cloud backend, frontend, and DevOps. I build software that puts models to work on real problems, from productivity tools to enterprise architecture. Based in Poland, shipping worldwide.
Selected work
Ideas become working systems.
Productivity tools that actually help
productivity.vtehsol.comEnterprise patterns with diagrams, code and live demos
patterns.vtehsol.comOne person.
The whole system.
From a first model to the thing your users touch.
Cloud backend
Domain-modelled services on serverless and container runtimes, built to stay cheap at low traffic and boring under load.
Frontend
Fast, accessible, framework-light interfaces. This site ships as static HTML under 15KB with no third-party scripts.
DevOps
Infrastructure as code, CI that actually gates merges, and deploys dull enough to run on a Friday.
How I build
- Model the problem first.
Domain-driven design: keep the domain pure and testable, and push infrastructure to the edges behind ports.
- Test through real collaborators.
Tests exercise real collaborators rather than mocks, so they describe behaviour instead of implementation.
- Ship it dull.
An append-only engagement journal, analytics that record no personal data, and deploys dull enough to run on a Friday.

One email a month on AI engineering across the stack — what I built, what broke, and what I would do again.
