• I worked as a Lead Gameplay Programmer on the Cyberpunk 2077 AAA RPG game, where my main responsibility was to build and drive the team of gameplay programmers, including UI sub-team.
• I still did a lot of coding, trying to keep a balance of 50/50, which obviously was not constant, and sometimes I had more time to write code, sometimes I had to focus on the team more.
• From programming tasks I worked on vehicle physics and handling, but also on more engine-side tasks, like input system or dynamic runtime database. I've also established the architecture of the current iteration of our internal engine, in cooperation with leads of other code teams.
• The Leadership role in CDP combined EM and some areas of PM responsibilities.
