Summary
🤩
Rockstar🎓
Top SchoolKevin Sung is a pragmatic software engineer based in San Jose with a decade of engineering experience and over seven years focused on software design and development. At IBM he designs and ships core cloud load balancer services and appliances, contributing end-to-end components from Linux appliances and gRPC microservices to REST APIs, automation, and platform integrations. He pairs production-grade cloud engineering with a deep interest in quantum computing—contributing backend fixes, operator improvements, and algorithm work to high-profile open-source projects like Cirq, Qiskit, and OpenFermion. Kevin’s strength is refactoring and hardening core libraries to improve usability and performance, whether speeding fidelity computations or adding operator algebra to quantum circuit libraries. Fast-learning and self-motivated, he bridges infrastructure reliability and research-oriented algorithm work, making him effective at moving experimental code towards production readiness.
