Yehor Kaliberda — AI Systems Architect · Aarhus, DK
I build autonomous AI systems that do real engineering work and prove it: merged pull requests, machine-checked verification, audit trails you can replay.
Shipped — CallMed AI
CallMed AI is my one-person agency for autonomous Python codebase audits. The proof is public: real pull requests, reviewed and merged by maintainers who had no reason to be kind.
Autonomous type annotation · shipped
Parses a Python repository into a typed AST dependency graph, then writes PEP 484 annotations under collision-free file locks. Strictly additive: logic, comments, and docstrings stay untouched. Delivered as a single reviewable PR with 0 pyright errors.
Autonomous security remediation · shipped
Runs five scanners in parallel, triages findings, generates one focused fix per finding, and verifies each through a three-gate deterministic pipeline before opening a draft PR. Entirely on-premise. A fix that fails any gate is discarded, never pushed.

In build — 2026
A multi-agent system that rediscovers physical laws from raw data, then proves them in Lean 4. Nothing counts until the proof compiles.
Read the build notes →A productivity agent that watches your screen, redacts anything private before inference, and runs entirely on a 4 GB consumer GPU.
Read the build notes →A developer-tooling product in the verification space. Named and public the day it ships, not before.
