// 01 · about

From game client to server

I spent almost two decades in the games industry at studios like Jam City, Plai Labs and Bacon Games, building meta-game systems, in-game stores and live-ops features for titles such as FIFA Rivals and World War Doh.

The part I enjoyed most was always behind the screen: wiring clients to REST APIs, syncing player inventories and progression in real time, integrating backends like Beamable and Firebase, and profiling until every millisecond was accounted for.

Today I'm taking that full-time into backend engineering: designing APIs, data models and services with the same obsession for performance and reliability that high-traffic games demand.
