Gabriel Kaszewski

Software Engineer

Who am I?

Hi, I'm Gabriel Kaszewski — a Bioinformatics graduate and a software engineer by trade. I’ve been obsessed with programming since I was 11, and I thrive on building software that solves complex, real-world problems.

My most ambitious project to date is my first game. You can check out the Steam preview below — if it catches your eye, I’d love for you to add it to your wishlist!

Currently, I am a Software Engineer at WPP Media. When I’m not at my day job, I’m usually deep-diving into new technologies or bringing my own side projects to life.
