I'm Roman Šafranko — a software developer working across computer vision, local LLM tooling, and browser-first products. My bachelor's thesis taught a robotic arm to take plain-language voice commands and carry them out, entirely offline. I like the part where every piece has to work at once.
01 Detections
A Dobot Magician that takes instructions in plain language. Speech-to-text feeds a locally hosted LLM with tool-calling; those tools drive OpenCV detection, OCR, and a homography that maps camera pixels into arm coordinates. Nothing leaves the machine.
A browser music visualizer aimed at short-form video. Web Audio drives the real-time analysis, several visual modes render to canvas, and LRCLIB lyrics stay in sync — clean 9:16 output without ever leaving the tab.
A stats platform for Teamfight Tactics on top of the Riot API — player lookup, match history, composition analysis, and the internal tooling that turns raw match data into something you can actually read a meta out of.
A résumé builder with live preview, an ATS-safe mode, and content linting as you type. Everything runs client-side, so editing stays instant and the document never leaves the browser.
02 Heuristics
I'd rather have one complete system than four impressive fragments. Prototype, interface, integration, deploy — the interesting engineering is in making them hold together, not in proving any one piece alone.
The expensive bugs live where two systems meet. I instrument the seams first and trace the whole flow before I start changing things in the middle.
I want to be able to open the thing that broke. In practice that means fewer dependencies, and actually understanding the ones I keep.
Clear scope beats broad scope. I'd rather a tool do one job precisely than ten jobs approximately.
03 Capabilities
04 Output
I'm looking for software engineering roles and freelance work — web, backend, vision, LLM tooling, whatever the problem actually calls for. Email is best; you'll hear back inside a day.
