I've been present in the tech world since 2020 when I created Redinn, a web agency which to this day puts performance and quality at the forefront of every project. Throughout years, I've experienced working in various environments, from startups (i.a. Poznaj Góry), through middle-size companies (i.a. Optima Medical) to corporations (i.a. AVSystem).

My skill set is constantly expanding, and currently includes devops, frontend and backend development with various technologies (listed in my résumé).
