Pilot
A project and task management SaaS built end to end with my own agentic toolkit: Rails 8 API, React + TypeScript SPA, Kamal 2 deploys, tag-only releases and one-click rollback.
HI! I'M OLEH, NICE TO MEET YOU.
Ruby on Rails engineer with 5+ years across EdTech, UK healthcare and fintech. These days I build AI product features — and the agentic workflow that ships them.

01 / THE WALL OF IDEAS
Some of these run in production. Others are the tools I built to ship them. All of them taught me something worth keeping.

One server, many isolated VMs: dev environments, a self-hosted GitHub Actions runner and workspaces where coding agents run unattended — reachable over SSH and RDP.
My AI-driven delivery toolkit: Claude Code plugins, Archon factory workflows and spec-driven delivery — PRD → TRD → ADR → a tested, reviewed PR.
At ManageBac I built the backend of an AI assistant chat, one-click prompt chips and LLM token-usage analytics — and shaped MCP tools around the chart queries users already trust.

02 / ON THE WORKBENCH
Three tiny experiments you can poke at. No polished magic tricks here — just the thinking made tangible.
03 / THE PERSON BEHIND THE TABS
PERSONAL NOTE / FROM COMPUTER ENGINEERING TO AGENTS
I studied computer engineering (M.Sc., Khmelnytskyi National University) and came to Ruby on Rails in 2019. Since then I've worked on systems where mistakes are expensive: a national UK NHS dental triage service that routed 100K+ referrals, an IoT platform at FluentPet, and a crypto exchange.
At ManageBac — a learning platform used by 3,000+ IB schools — I built the backend of the AI assistant chat, prompt chips and token-usage analytics in a 10+-year Rails monolith. Along the way: pentest findings fixed across 3 vulnerability classes, test coverage up 40%, p90 query latency down 15%.
Now I build Pilot end to end with my own agentic SDLC toolkit. My favorite part hasn't changed: ask why first, reuse what already works, and only call it done when the evidence says so.

05 / OPEN ANOTHER CONVERSATION
A Rails codebase that needs care, an AI feature that has to earn its cost, or a team adopting coding agents — I'm open to remote B2B work and good conversations.
