Alexander Marcinkevičius

Product leader, builder, and operator rooted in software engineering.

I work at the intersection of product, technology, and execution—from early-stage ventures to enterprise systems. Scale-, role-, and stack-agnostic: leader or IC, in-house or fractional.

  • Ventures & Products: Building and operating via Geekchester, including Athlon Games and a few other projects.
  • Open Source: Occasionally packaging pragmatic tools born out of real needs, e.g. gsm2http or rmStrokes.
  • Focus: Building & Distributing, Applied AI, Agentic workflows.
  • Background: Software engineering, product lead, engineering manager, college lecturer, entrepreneur.

Outside of work: football (playing & coaching), bikepacking, singing, snowboarding.
