I fix stuttering, lag and multiplayer desync in Unreal Engine 5 games, and I build the gameplay systems around them. My last title, an action game, ran at a locked 60 FPS on the Tokyo Game Show 2024 floor after I cut its frame-time hitches by 98%. Seven years in Unreal, UE 4.22 to 5.8, with ten titles shipped across five studios. I work Blueprint-first and drop into C++ where the engine demands it: exposing native functions to Blueprints, wrapping third-party SDKs as typed nodes, reading callstacks Blueprints cannot reach. What I have shipped: ▪ Performance. Took a Steam action title from below 30 FPS in some scenes to a locked 60 on an RTX 3060 8GB. Cut level load times by 40% with PSO caching, shader warmup, soft references and Tick cleanup. ▪ Multiplayer. Lifted a UE5 metaverse from 10 to 40 concurrent players by fixing replication: relevancy, dirty flags, server-validated RPCs, dedicated servers on AWS GameLift. ▪ Gameplay systems. Owned ten systems on one title, including combat state machines, abilities, AI with behavior trees and navigation, QTEs, dialog and objectives. ▪ VR. Meta Quest 2 standalone locked at 72Hz: under 1M triangles, under 150 draw calls per eye. ▪ Fortnite UEFN. Lead developer on six live islands written in Verse. The flagship held about 100 daily players, peaking near 200. ▪ Pixel streaming. Browser-based UE5 on AWS for Unilever's TRESemmé launch, covered by IGN Pakistan and BeautyMatter. ▪ AI characters. Custom C++ mic-capture and WebSocket plugins feeding NVIDIA Riva, Llama 2 and Audio2Face into a MetaHuman, under 2 seconds end to end. Jobs I take, small or large: ▪ A single bug or crash fix in Blueprint or C++ ▪ A gameplay system built from scratch or rescued from technical debt ▪ Multiplayer setup, replication fixes, dedicated servers ▪ Performance audits for PC, mobile and Quest ▪ UEFN and Verse, pixel streaming, VR training, product configurators Fixed-price jobs from $300-$500 are welcome. A solo developer gets the same process as a studio. How I work: I read your project or profile your build first, then send a written diagnosis and a fixed quote. You get a short video of each fix running, plus notes your team can maintain. Available now, full-time. Based in Lahore (UTC+5), overlapping EU business hours and US mornings. Send me the bug or the frame-time graph. I will tell you what I think is wrong and what it costs to fix.
