Research and Open Source
D-GIX · Geospatial retrieval research
Co-authored research at Polyhistor on spatial and semantic search across more than 3.55 million points of interest.
STAIR · Independent retrieval reproduction
Compared four retrieval methods on one openly licensed textbook. BM25 led overall, while STAIR beat DSI on depth-2 sections and trailed it on depth-3 leaves.
On the frozen set of 1,758 questions, with 129 candidate leaves and 86 represented gold leaves, Recall@1 was 0.7986 for BM25, 0.6553 for NV-Embed-v2, 0.4010 for DSI, and 0.3754 for STAIR. The reproduction follows the STAIR paper by Vineet Kumar and colleagues. The repository documents the split, checks, and LoRA implementation.
PriviLAB · Open-source contribution
Contributed to the source-only Developer Preview created by Andrew Tsintsiruk and built by Data Strategy Lab. Restricted live SDK use by default, added regression coverage with synthetic fixtures, and added contributor and repository checks.
More Work
ShipSolid · Developer CLI
A TypeScript and Node.js command-line tool that processes Semgrep findings, uses Claude to assist analysis, and generates PDF reports.
Aura · Earlier design work
A Figma prototype with mobile shopping screens and reusable component variants.
