The largest Croatian gambling company with hundreds of locations all over the country and a solid online presence. I worked as the back-end developer for the in-play betting system. I migrated the old in-play system written in Elang to a Go-based microservice and included additional in-play providers into the existing system. Afterward, I worked on maintaining and expanding the in-play system with other offerings and optimizing the performance in such a crucial part of the system.

Erecruit is one of the world's largest staffing and HR software solutions. I took part in a team working on the timesheet processing engine that covered various client specifications for several huge clients all over the USA. The engine was designed to process tens of thousands of timesheets daily, covering several legal regulations across various states. Since reliability was critical, writing unit tests and end-to-end tests was of the utmost importance.

A puzzle-programming video game that uses a custom node-based programming language to control robots and solve puzzles. It was created as a side project, released in Early Access, and maintained and improved over six months before a full release. I was the lead game designer and programmer and managed a small team of artists while also taking care of the release schedule.
