Hi, I'm Heorhii.
I turn messy business processes into software that runs itself.

Fullstack developer, 2+ years in production. I build SaaS platforms, integrations and AI agents that take routine work off people. My systems run in production for real clients: they draft legal documents, answer customers in 11 languages and handle orders without anyone watching.

What I've built lately

Projects I can talk about in detail. The numbers come from the running systems.

MACEK.LEGAL

Document automation for a Czech law firm

2025 to now
Client project, built by me end to end

The platform drafts legal documents and reviews contracts that come from the other side. I did the architecture, backend, frontend, servers and the AI layer.

MCP tools the agent can call

court decisions in search
1¢
roughly, per document
  • 18 document types in 8 modules. Contract review marks risky or missing clauses and exports DOCX with real tracked changes.
  • An MCP server with 32 tools for the in-house agent, Hermes. It writes and edits documents, keeps track of case deadlines, searches case law and reads scans with a vision model.
  • A custom OpenAI-compatible proxy in front of the models. It strips personal data before anything leaves the network, routes between providers and counts cost per document. Hosters of the same model differed in speed up to 23x, so each model is pinned to one of them.
  • When a lawyer corrects a mistake or dictates a rule, it applies to every future document.

Omnichannel AI Support

AI support and sales for an online store

2025 to now
Client project, built by me end to end

One dialog engine answers in Telegram, the site widget, Instagram, Facebook and email. Before a reply goes out, code checks it for made-up facts.

919
tests, each from a real incident
11

5,963
orders in the store
3,400+
emails per bulk send
  • Channels are thin adapters over one core, so the catalog, prices and escalation rules live in one place.
  • Three checks run before every reply: facts must come from real data, the language must match, and the bot can't promise what it can't do.
  • An email bot over IMAP/SMTP. It sorts mail into 8 categories, answers in 11 languages, keeps threads intact and can run anywhere from drafts only to fully on its own.
  • Operator panel in Next.js with live updates over SSE, chat takeover, broadcasts and a prompt editor. Bulk mail follows RFC 8058 one-click unsubscribe.

  • A separate mobile layout without an SPA framework: bottom sheets and collapsible blocks you can use with one hand.

04/About

I like owning the whole thing: schema, API, agent, UI. And I like it even more when it surprises people.

Fullstack developer and AI engineer from Ukraine, working remotely. I build SaaS platforms and the AI agents inside them, and my systems run in production for real clients: legal document automation, omnichannel customer support, ERP/CRM.

I care about the unglamorous parts of AI: guardrails in code instead of hopeful prompts, cost and latency measured per request, and a test for every incident so it never comes back.
