Y Özer is a Berkeley-based computer science student and founder with four years of hands-on software engineering experience across blockchain, climate tech, and research labs. They interned at Aptos Labs as a performance engineer, adding CPU and memory profiling to a high-profile Layer 1 blockchain project and integrating tools like pprof and jemalloc into executor benchmarks. Y combines systems-level performance work with product-minded engineering from roles at Automata Network and CoolClimate Network, demonstrating fluency in both distributed systems and applied sustainability tools. As founder of Revleno, they are translating technical depth into entrepreneurial leadership while still completing a dual-degree education in CS and Economics (3.77 GPA) at UC Berkeley. Notably, their open-source contributions show an emphasis on observability and low-level optimization—skills that often go unseen but materially improve production reliability.
