Summary
🤩
Rockstar🎓
Top SchoolEzra Chung is a Senior Software Engineer with four years of professional experience specializing in C and C++ development, focusing on core libraries, frameworks, and long-term ABI-stable multi-platform libraries. At MongoDB he has contributed to the official C and C++ drivers and the specifications repo—improving test coverage, client-side encryption support, and subtle driver behaviors such as SRV polling and BSON subtype handling. His background includes modernizing legacy C++ code, reducing technical debt, and delivering high-performance data conversion tooling that cut processing time by over 90% during an earlier internship. Comfortable across backend systems and test automation, he combines careful low-level engineering with a pragmatic eye for documentation and maintainability. Notably, his open-source work touches widely used, production-critical projects in the MongoDB ecosystem, reflecting both deep language-level expertise and an ability to influence cross-project specifications.
