22 USD Vibe Coding Training: AI as an Amplifier, Not a Replacement
Tuition
Growing demand for vibe coding education — I work with three types of clients:
▸ Vibe coders — already burned, still believing in the magic. Format: small group online workshops with a real project, prompting system, and daily techniques.
… ▸ Non-IT professionals — marketers, managers, product people — who want to boost results with AI without going deep into programming. Same group format, focused on their tools.
▸ Those who want to grow seriously — individual mentoring and coaching: your project, your pace, targeted feedback.
Learning is built around real projects from your field. AI amplifies what's in your head — smart input gets great results.

111 USD AI Voice Agent — 20K Calls/Month, 80% Automation
AI & Machine Learning
Voice AI agent automating inbound customer support calls for a micromobility startup. ~20,000 calls/month. Delivered in 24 days.
Operators spent 80% of their time on 4 recurring scenarios: trip completion, lock failures, red-zone violations, app freezes. The bot now handles all four autonomously — queries CRM in real time, takes action, closes the call.
… Result: ~80% of calls resolved without operator involvement.
Architecture:
Binotel webhook → Whisper STT (UA/RU) → GPT-4o-mini → CRM API → ElevenLabs / Azure TTS
Key solutions:
- Latency: all fixed phrases pre-generated via ElevenLabs and cached. Azure TTS only for dynamic responses
- CRM queries run async during audio playback
- Out-of-script → transfer to operator with full call context
Stack: Go · Binotel · OpenAI Whisper · GPT-4o-mini · ElevenLabs · Azure TTS · Redis · PostgreSQL

111 USD AI Application Assistant — Telegram Bot for GovTech
AI & Machine Learning
Conversational AI assistant as a Telegram bot for a Ukrainian consultancy helping small businesses apply for government and EU grant programs.
Problem: 1 application = 2–4 hours of consultant time. 50+ clients/month.
… Architecture:
- RAG + LLM classifier (pgvector HNSW + OpenRouter) routes to correct program
- LLM function-calling extracts facts from 10–20 client messages
- Donor-specific rule validation (funding limits, min employees, eligible categories)
- Excel template filling — input cells only, formula cells untouched
- Operator escalation with full context when AI confidence drops below threshold

67 USD KeepinCRM Automation for an E-Commerce Store
Enterprise Resource Planning (ERP)
Built a Go daemon that fully automates the CRM workflow of an online store: moves deals through the sales funnel based on Nova Poshta delivery statuses, generates fiscal receipts via Checkbox (Ukrainian ПРРО), and sends SMS notifications to customers via TurboSMS.
What was built:
… - Automatic deal progression through a 7-stage sales funnel: Nova Poshta statuses mapped to KeepinCRM stages, with a CRM comment added on every transition.
- Fiscal receipt generation for COD and NovaPay payments: receipt issued when the parcel is picked up by the buyer (NP status 9), payment type — "Integrator payment NovaPay".
- WayForPay fiscalization without waiting for a tracking number: parallel agreement scan via GET /agreements — receipt issued immediately when the order appears in CRM, before a waybill is created.
- SMS notifications: #1 on waybill creation (tracking link), #2 on arrival at the branch, #3 after fiscalization (link to the public fiscal receipt).
- SQLite deduplication: every event (stage move, SMS, receipt) fires exactly once — no duplicates regardless of polling frequency.
- Deployed as a systemd unit on the client's VPS, running 24/7; watchdog cron + daily database backup.
Stack: Go 1.24+, SQLite, systemd, KeepinCRM API, Nova Poshta API, Checkbox ПРРО API, TurboSMS API

67 USD AutoGA — Automated AI-Powered News Digest
AI & Machine Learning
Built a fully automated pipeline that turns Google Alerts into a Telegram channel digest: RSS feed → article scraping → LLM summarization → Telegram delivery.
What was built:
… - Go HTTP service for article scraping: accepts a batch of URLs, concurrently extracts clean article text using Mozilla Readability, returns structured JSON. Deployed on Google Cloud Run.
- Make.com integration: developed a CLI tool that programmatically deploys complete automation scenarios via Make.com API — a single command sets up the full flow for any list of RSS
feeds.
- Deduplication via Upstash Redis: each article is processed exactly once, no repeated notifications.
- Ukrainian-language AI summaries via Ollama Cloud LLM.
- Robust edge-case handling: JavaScript-rendered pages, paywalled content, YouTube URLs, Google Alerts redirect unwrapping.
Stack: Go 1.25, Google Cloud Run, Make.com, Upstash Redis, Ollama Cloud, Docker, Telegram Bot API
