Stanislav Shupilkin — Data & AI engineering and mentoring
Tech Lead, Data & AI at Unimatch — Belgrade
I'm Stas — engineer, then engineering manager, now Tech Lead in Data & AI at Unimatch. Ten years of high-load e-commerce: I moved procurement onto durable workflows, taught teams to trust dashboards over gut feeling, and grew engineers into leads. After hours I build voice tools, a real-estate bot, and whatever else I’m currently stuck on.
work with me
- Data-driven engineering transformation — For teams deciding on gut feeling: analytics stack, KPIs, and dashboards the business builds itself.
- Practical AI strategy — For companies with more AI ideas than capacity: pick the use-cases worth shipping, drop the rest early, measure ROI.
- Career coaching for engineers & leads — IC or management? We map strengths and leave with a plan short enough to follow.

Side projects as they are, real numbers included — even the ugly ones.
- Apify actors — Five ready-made scrapers in the Apify Store: Telegram channel search and voice transcription, audio and video to subtitles, Serbian property listings with cross-portal duplicates collapsed, and a 24-hour X trends timeline. You pay per event — a row, a minute of audio; compute comes out of my margin, so not one of them runs a browser. all five how it works store profile
- Voice AI — Speech-to-text and text-to-speech: Telegram bot, web app, Chrome & Firefox extensions that read pages aloud. Long recordings survive restarts thanks to Temporal. try repo
- Pet Project Atlas — An open atlas for side projects: demand, indexing, AI search, content, distribution, analytics, money. Every page comes from a real log of my own projects — what I ran, what broke, what came out. Numbers carry a date and a source, and CI fails the build when they do not. read repo
- Blizu — Telegram bot for Serbian real estate: send a location, get every listing nearby from the aggregators, merged into one card. Postgres + PostGIS + Temporal crawlers. bot
- Smolevich AI Bot — One Telegram chat, dozens of free LLMs from three providers — Groq, NVIDIA, OpenRouter. With a live leaderboard of which free models are actually good, from my own benchmark. bot leaderboard repo
- This site — Also a lab: Whisper speech-to-text running fully in your browser (WebGPU) and a notes app you can query with SQL via DuckDB-Wasm. Audio and notes never leave your device — there is no backend. whisper notes
