Cases

Real project examples: what was done, with which tools and with what result.

AI · RAG

Knowledge-base RAG assistant

A company with hundreds of internal documents. I deployed a private RAG: documents are split into fragments, searched by meaning, and a local model writes the answers. Nothing leaves the server.

Search < 2 s · 100% private
Servers · Security

VPS migration and hardening

A live project moved to a new server with zero downtime: Docker containers, Nginx proxy, fail2ban, nightly backups and monitoring. No incidents since.

AI · Bots

Customer support Telegram bot

An LLM-powered bot answers typical questions about services and prices, captures leads and hands complex cases to a human. It closes up to 80% of requests.

Servers · DevOps

Monitoring and alerts

Built a monitoring stack: Grafana, server and service metrics, Telegram alerts with context. I now spot downtime before clients do.

Reaction time: minutes
AI · Automation

Document automation

Invoices and contracts are generated automatically from CRM data: template + substitution + delivery to the client. It used to take half a day.

Hours of routine → 2 minutes
Neural networks · LLM

Local LLMs with no cloud

Deployed Ollama with Open WebUI on a private server: private chats, text generation, work with documents. API costs cut up to 10 times.
