Senior🎓
Top SchoolJinsu Lee is a C++ development expert with 9 years focused on query processing and compiler stacks, currently driving advanced database features at SAP Labs Korea. He has led teams and owned end-to-end components such as SQL Script Compiler, SQL Optimizer with Smart Data Access, and SQL Update Compiler, combining hands-on implementation with small-team leadership. His work spans optimizer innovations (distribution- and parameter-aware planning, plan stability, logical/physical transformations) and quality initiatives that boost test coverage and reduce compiler warnings. Comfortable as a generalist within the query processing domain, he deliberately bridges implementation, design and cross-team communication to streamline collaboration. Based in South Korea and educated in electrical and electronic engineering at Seoul National University, he brings a systems-thinking approach to database internals and federation. A pragmatic contributor, he often pairs feature development with tooling and documentation improvements that make complex compiler behavior observable and maintainable.
