Hello

What I'm Building

• DocQuery — document to structured JSON extraction, fine-tuning Qwen2-VL-7B + LayoutLMv3 (LoRA/QLoRA)
• picrawler-rs — Rust rewrite of SunFounder's robot_hat for a PiCrawler quadruped, reverse-engineered HAT register maps
• Photorealistic Street Maps — open-source 3D cityscape reconstruction from Mapillary/OSM/Overture using COLMAP SfM

Open Source Contributions

Python, OpenCV, PyAV

• Optimized single-box IOU calculation by eliminating redundant intersection computation on the fast path — 2x speedup, no API change (PR #1874)
• Built a spline-based line annotator that interpolates smooth paths through noisy per-frame tracking output, removing visual jitter in rendered object trails (PR #1919)

Rust, Luau

• Extended the linter to recognize Luau/Roblox EnumItem properties, eliminating false-positive lints (PR #670)
• Added const declaration support to the Luau parser path, with regression tests (PR #673)
