Senior Software Developer — banking systems

Athens, Greece snakemjk@gmail.com papaspyrou.dev linkedin.com/in/zisisp github.com/snakemjk

Banking IT engineer who works on systems where downtime isn't an option. I like hard problems, clean code, and infrastructure that doesn't wake me up at 3am. Been doing this long enough to know what matters and what's just noise.
