Samed Kahyaoğlu

Engineer in Istanbul. I build the hard parts and keep them running. Former tech lead at a regulated crypto exchange; now independent as Lucky S Software.

Building now

  • Drumbeats: monitoring for websites, APIs, cron jobs and background tasks. Live.
  • İyi Seans: practice management for psychologists in Türkiye. In development.

Along the way

  • 2026: psytools, Drumbeats MCP server, onekey-locker
  • 2023–26: tech lead at BiLira Kripto. We built the exchange and ran it in production.
  • 2023: block-id, ETHGlobal Istanbul, zero-knowledge KYC (live demo)
  • 2022: tc-id, Turkish ID validation on npm
  • 2021: open-tendering-in-ethereum, my ITU graduation thesis; tweet-verifier
  • 2018–19: first steps in C, C++ and the web

Older projects were restored in 2026 with tests and live demos, with help from AI agents. Each keeps its original code under an original-<year> tag.
