Who I Am
Hi, I’m Justin Chellah, a self-taught game developer with over 9 years of experience creating mods for some popular and successful Valve games like CS:GO, Team Fortress 2, and Left 4 Dead 2. From 2016 to 2021, I ran my own Left 4 Dead 2 gaming community, Unity Gaming Network, where we hosted PvP servers featuring many custom and unique mods – most of which are showcased in my portfolio.
Unity Gaming Network grew into a popular and competitive community, attracting players from around the world. Some of the mods we developed were inspired by the gameplay of CS:GO, adding unique twists and challenges without breaking the balance or fun of the server. Running the community taught me not just game development, but also how to design engaging experiences for players and run a lively multiplayer community.
This experience with my own servers also gave me the chance to work directly with the Source SDK (the engine Valve used for their games), including the versions used for CS:GO and TF2 – and that’s how I built the skills that make me good at what I do today.
The Early Days
At 14, I began learning how to mod and develop plugins for Counter-Strike 1.6 on the GoldSrc engine. I found the creative process so fulfilling that it quickly became more than just a hobby.
Between those early days and 2016, I also spent time developing multiplayer cheats for games like A.V.A (by NEOWIZ) and Call of Duty 4, which gave me my first hands-on experience with game internals, memory manipulation, and reverse engineering.
