Hello,

I am Qasim Obaidullah

I am a Unity and Unreal Engine game developer creating scalable, performance focused games across PC, mobile, AR, VR, and XR platforms. My work centres on clean gameplay systems, modular architecture, and player driven design that balances creativity with commercial awareness.

In Unity, I specialise in C# development for mobile, AR, and VR games, with experience in hyper casual mechanics, third person controllers, analytics, telemetry, and rapid prototyping. In Unreal Engine, I build gameplay systems using Blueprints, focusing on locomotion, combat, interaction frameworks, AI behaviour, and optimisation for production ready builds.

I also design and integrate monetisation systems including rewarded ads, in app purchases, progression based economies, and analytics driven retention strategies, with a strong focus on ethical monetisation.

I provide professional freelance services on Fiverr and Upwork, offering game prototypes, gameplay mechanics, Unity and Unreal development, AR and VR solutions, optimisation, bug fixing, monetisation setup, and technical consulting for indie developers, studios, and academic projects.
