At A1 Austria Telekom: I'm leading platform engineering and release ownership on a high-impact telecom system. Right now that means Java 22, Spring Boot, Oracle, and the release side of a team-wide GitHub migration.

Bitcoin infrastructure: Maintaining explore21.com, a block explorer I built because the one I wanted didn't exist. It stays in sync with the chain tip and tracks what I actually check: difficulty, hash rate, mempool depth. Also exploring Surplus Miner, a controller that load-matches ASIC miners to solar surplus.

Writing: Every two weeks I publish Explore21 бюлетин, the first Bulgarian-language Bitcoin newsletter: what the charts actually show, where the cycle sits, no price calls. The charts it draws on live at charts.explore21.com. Eleven series, refreshed every ten minutes off my own node.

TODO(dimitar): This page is only worth having if you update it monthly. If it drifts more than two weeks old, delete it or mark it as stale.
