About
Innovative and adaptive programmer with a rich background in the gaming industry and a passion for creating immersive visual experiences. With over 15 years of expertise, I have successfully transitioned from a talented graphic artist to a proficient developer, focusing on memory and runtime optimization, 3D rendering, low-level graphics APIs and console development. My experience spans across various platforms, including web, mobile, PC, and console gaming.
I pride myself on my ability to learn, adapt, and grow in this ever-evolving industry. As a self-taught programmer, I’ve gained invaluable hands-on experience and sharpened my problem-solving skills to tackle complex projects head-on. My diverse skill set and artistic flair uniquely position me to excel in roles that blend creativity and technical acumen.
When I’m not immersed in the world of gaming, I find solace in watercolor painting and keeping the legacy of classic systems alive through writing assembly software for the Game Boy and Commodore 64. I am always eager to connect with fellow professionals and enthusiasts to exchange ideas, collaborate, and explore new opportunities in the gaming and tech industries.

Sr. Game Programmer at Globant

For the past 2 years I’ve been working on the development of WBGame’s Hogwarts Legacy. My focus has been CPU and memory optimizations for PS4, PS4 Pro, Xbox One, Xbox One X, Windows and the Unreal Engine 4 Editor. I mostly focused on memory optimization where I’ve worked developing platform specific solutions for reducing memory usage, improved Unreal’s default allocator and did R&D on different allocators to help reduce wastage and thread contention. Developed several memory tracking tools. For example, I created a tool that helped with tracking the size of our structures where we could reduce memory usage by adjusting the position of data members, also developed tools that helped us understand the allocation patterns we made and gave us more information on when and where these allocations happened.
