Taras Koval — automation engineer
n8n workflows, Telegram bots, CRMs, integrations, self-hosted infrastructure. I take subcontract work from agencies.
Production, not tutorials
All of it runs on infrastructure I set up and maintain myself: self-hosted n8n, PostgreSQL, Docker, Cloudflare. Not a managed account with three demo flows. I'll walk you through the instance on a screen share.

Screenshots are from a demo instance with synthetic data — no real patient or client records are shown anywhere on this page.
Sites
Selected work
CRM for a language school
The school ran on a dozen Google Sheets — schedule, payments, leads, debts. Every one of them maintained by hand. Replaced with a single system.
- Leads from the web form and Instagram land in one queue instead of four places
- Group scheduling, attendance, teacher load
- Payment tracking with automatic reminders for unpaid months
Telegram CRM with AI agents
A sales flow that lives entirely inside Telegram. The customer never leaves the chat, and neither does the operator.
- Button-driven qualification with session state in Postgres
- LLM agents for classification and reply drafting, structured JSON output
- Retrieval over the client's own documents (pgvector)
- Handoff to a human with the full conversation as context
Integrations and infrastructure
The unglamorous half of the job — and usually the half that decides whether a project survives contact with reality.
- REST integrations between CRMs, messengers, spreadsheets, payment providers
- Server setup, Docker deployment, domains and TLS, backups
- Error trapping and alerting, so a failure shows up in chat rather than in silence
Working with agencies
| Client clause | I work under your brand and do not approach your clients. Happy to sign whatever confirms that |
| Rate | $25/hour, or a fixed price per defined scope — whichever you prefer to work with |
| Availability | 30 hours a week, starting immediately |
| Timezone | UTC+7. Work handed over in your evening comes back done in your morning |
| Handover | Documented workflows, credentials in your accounts, no lock-in on me |
The client clause is listed first on purpose. It is the thing agencies actually worry about with a subcontractor, and it deserves a straight answer rather than a hint.
