Software Engineer | Technical Game Designer

From working with Amazon game studios, AWS, and indie game development, I specialize in programming gameplay systems, tool engineering, networking and game design. With a passion for creating immersive experiences, I strive to push myself to be a better engineer daily.

My journey as a game designer and software engineer has been filled with exciting challenges and rewarding achievements. I believe that every project is an opportunity to learn and grow, and I approach each one with enthusiasm and dedication. I am constantly seeking new ways to innovate and create memorable gaming experiences.

Take a look at my portfolio to see some of my past projects, and feel free to reach out if you have any questions or collaboration opportunities.

Ragui Halim, Software Engineer - AWS Route 53

I had the privilege of mentoring Excell as an AWS Route 53 intern for 2 consecutive summers.

With guidance, Excell demonstrated the ability to comprehend complex problems, effectively communicate with different teams to collect design requirements, design solutions to the problems, and successfully implement them. Excell designed and implemented a system in 2022 that is now being used, as part of a larger system, to protect Route 53 customers against DDoS attacks.

Excell's dedication and adaptability make him a valuable asset to any team, and I am confident in his potential to excel in future endeavors.
