Shaokai contributed to the lf-lang/lingua-franca and lf-lang/reactor-c repositories by developing and refining features for distributed and real-time systems. Over four months, Shaokai enhanced federated code generation, improved event scheduling semantics, and strengthened test infrastructure, focusing on reliability and maintainability. Using C, Java, and Python, Shaokai addressed cycle detection in distributed workflows, refactored scheduler logic for predictability, and resolved type-safety issues in embedded C modules. The work included updating submodules, standardizing test policies, and optimizing build tool configurations. These efforts resulted in cleaner codebases, more robust scheduling, and improved test coverage, demonstrating depth in compiler and concurrency engineering.

November 2024: Delivered Scheduler Selection Simplification in lf-lang/lingua-franca by removing the deadline-based GEDF_NP logic, resulting in a simpler and more predictable scheduler decision path. Eliminated pickScheduler() and its helper hasDeadlines() in CGenerator.java to reduce dead code and maintenance burden, enabling easier future policy experimentation. Core commit: 9bd8dacdba9de15f22dd784e4b9077f01c2625f2. This work improves scheduling determinism, reduces risk of deadline-driven edge cases, and accelerates future enhancements.
