My name is Vadim Gierko and I'm in β€οΈ in web & SaaS development since 2021 π
Although I've created various static & dynamic websites (check out my personal website) and online e-commerce stores from scratch, my greatest dev ambition & passion is building real-world, end-to-end full stack web / SaaS applications people actually use (some of them are mentioned below).
Despite my wide range of interests & vast creative background, programming is my greatest passion.
I also share my knowledge & encourage others to learn to code in a free web dev course for office workers (in Polish).
