Available to hire
I’m Ramy Chalaby, a Principal Software Engineer with extensive game development experience, having released popular indie games and currently pursuing high-quality desktop game releases. I’m proficient in game development using Unity and Unreal Engine, and I’m eager to contribute to your upcoming title to ensure its success and worldwide acclaim.
I’ve delivered performance optimizations including a 95% improvement in Data Export on a real-time medical platform (reducing processing from 20+ minutes to ~1 minute). I’ve led cross-functional teams, mentored junior developers, and delivered reliable, scalable software across Unity, Unreal, and cross-platform tooling.
