Tomasz Giereś

Software Developer

A fledgling "Mr Engineer" who has yet to build his first bridge. Or railroad. Or rails? Tomek is well-versed in economics and makes our day 100% better by arguing about it over our morning coffee. He’s also a tender audiophile, ever-busy soldering and assembling new speakers from what he finds under his desk. Likes to bicker with Julia.

After work, Arek is learning how to sing and is doing it slowly, enjoying the process and cherishing the progress he's making.
