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

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.

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.

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.

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.
