Radio engineering student in Kyiv. I build small embedded devices and keep the infrastructure they talk to running.
Two seasons on the Ukrainian national team at the FIRST Global Challenge — Singapore 2023 and Athens 2024 — responsible for the robot's electronics: assembly, bring-up, and repairs between matches, when diagnosis has to fit into minutes.

water_counter_esp — a camera reads a mechanical water meter, ESP-NOW carries the value to a gateway, MQTT takes it from there. Built for a house that stands empty through the winter.
rt-n12-freshtomato-repeater — an Asus RT-N12 D1 turned into a transparent Wi-Fi repeater on FreshTomato. Mostly a writeup of the Broadcom driver quirks that fail silently and are documented nowhere else.
vps-vpn-hardening — a family VPN on one small VPS, with every management interface firewalled off the internet and reachable only through a WireGuard tunnel. Includes the checklist from auditing it.
Studying radio electronics, teaching programming to kids, and working towards embedded and infrastructure engineering.
Interested in devices that keep working when the grid and the internet do not, and in hardware you are still allowed to repair.
