Hi! I'm Krišjānis Petručeņa, a research assistant at the Institute of Mathematics and Computer Science, University of Latvia (IMCS). I spend my time frustrated by quantum-safe communication, software architecture, and confidential computing. I host an archive of latvian informatics olympiad problems (LIO) at programme.lv as a hobby. I'm happy to chat - email me at krisjanis dot petrucena at lumii dot lv.
