Hlib Stepanov

Second-year software engineering student at Taras Shevchenko National University of Kyiv. I work on applied AI: agents that act on a computer under the user's control, search over private documents, and benchmarks that turn "it works" into a number.

Open to junior AI engineer roles and internships, remote. LinkedIn · stepanovgleb10@gmail.com

Projects

Project What it is Measured
Halo Bot Desktop app where AI assistants do real work on your PC, each in its own Windows sandbox, behind an approval gate and an audit log On an 11-task benchmark a local 4B model went from 7 to 10 solved tasks (PR #14)
Glossa Ask your documents a question and get the answer with the page it came from. 35 languages, runs offline Retrieval pipeline in about 300 lines, no LangChain
vybir Runs an AI decision model on ordinary PCs and hands the cases it isn't sure about to a person Per-class calibration cut spam that got through from 23.8% to 3.5%; 183 tests
skillrot Shows how much of an AI agent's context its skill library takes up Weekly CI audit of 5 public libraries
VaultDrop Offline Windows backups that read back and verify every file Installer and CLI in v0.2.0
RoadForge Self-driving demo on real OpenStreetMap roads, in the browser Live demo; 0 collisions in 20 benchmark runs

Right now I'm training my own 158M-parameter language model from scratch on Ukrainian, English and code. That repo stays private until a checkpoint is worth sharing.

How I work

I write code together with AI coding agents (Claude Code, Codex) and hold it to the same bar as anything else: tests, CI, and a benchmark before I call a change an improvement. The numbers above come from those tests and benchmarks, not from estimates.
