Li T is a Quantitative Developer with 12 years of systems-first engineering experience across finance, robotics, and embedded platforms, currently contributing C++ to a core trading framework at Squarepoint. He brings deep expertise in low-latency, microsecond-sensitive systems—from multi-socket x86 servers to RAM-constrained ARM devices—and a track record of improving performance and correctness in production C++ code. At Mujin he led design and implementation of hard real-time collision detection for industrial robotics, shaving 3D mesh processing times by 20% and rooting out memory and concurrency issues with tooling like valgrind and gdb. Previously he built on-prem GPGPU/ML infrastructure at Rakuten, converting PyTorch notebooks into optimized C++ and shipping high-throughput log and orchestration tooling. An active open-source contributor, he has improved widely used projects such as sqlite_orm and OpenRAVE, and in his spare time maintains a personal finance database and self-hosts Deepseek V3—indicating a pragmatic blend of research curiosity and production discipline.

❤️ SQLite ORM light header only library for modern C++

Role in this project:

Back-end Developer

Contributions:9 reviews, 7 commits, 10 PRs in 1 month

Contributions summary:Li focused on improving the functionality and maintainability of the `sqlite_orm` library. Their work included fixing compiler errors, specifically related to insufficient braces in the code, and addressing shadowed variable warnings. They also extracted `sqlite3_step` into a separate function and updated the version number, indicating a focus on code refactoring and library maintenance. Additionally, the user implemented improvements with regards to one-shot queries and `perform_query_without_result` calls, essentially replicating `sqlite3_exec` functionality.
