Recent engagements.
Migrating a RAG copilot serving 5,000 users
Pitched and led a LangChain → LangGraph migration. Designed an observability adapter that broke a Literal AI vendor lock-in before it bit. Test coverage 40 → 80%.
Shipping AI features inside a SaaS platform
Owned an AI meeting bot and an AI weekly planner end-to-end, embedded with the platform team. Led a structured-outputs migration across legacy AI features.
Building an AI team from zero
Hired the developers, picked the stack, planned the architecture, and trained the team until they could ship without me. Walked out on schedule.
Engineer-led
consulting.
Most engagements are embedded build — I own AI features end-to-end for 3 to 6 months. Lighter shapes include a fixed-scope scoping engagement (€8–10K, 2 weeks), an advisor retainer, an architecture audit, and AI team setup. Shape gets decided on the discovery call. Remote, async-first, based in Warsaw (UTC+1). Three-month minimum.
Building AI for production?
30-minute discovery call. Bring the problem you're stuck on — I'll ask the questions a senior consultant would ask. No pitch, no commitment.
