whoami — Damian Fastowiec
With over eight years in Python development and automation, I build software that works in production. I combine enterprise-grade engineering with modern AI — where it actually helps.
My background isn’t prompting demos. It’s frameworks, rigorous testing, and scalable architecture: backends, data pipelines, RAG systems, and AI agents that your team can run and extend.
Full story: About Me
Many people can write a prompt. I build the production infrastructure around it: reliable Python backends, DevOps, and AI features that fit a real product.
Agents, RAG, APIs, and automation that ship and stay maintainable.
Architecture and delivery decisions when you need clarity this week.
Training and tools so your team can run and extend the work.
# principles — what I optimize for
assert right_tool # simple query beats an agent when it fits
assert built_to_last # maintainable, not demo-only
assert you_keep_it # specs, docs, training — not a dump
Documented plans. Reviewable milestones. Clear ownership.
Build. Consult. Train — billing that fits.
