    Software EngineerIllumibot (ArroyoDev)

    Ship across four surfaces — Flutter mobile, React web, Deno serverless on Supabase, and a Python/OpenCV service — for a two-sided marketplace with Stripe Connect payouts, Algolia search, and realtime messaging.

    Built the projector-to-surface computer-vision pipeline: homography, multi-projector stitching, ArUco calibration, and LoFTR feature matching on Apple-Silicon MPS, running on Cloud Run and consumed in-app through a hand-written GLSL keystone-warp shader.

  3. 003AxessProtocolPython / Aptos / Movegithub.com/aniJani/oracleAgent

    A marketplace for renting out idle GPUs, with payment settled on-chain. I built the host agent: it detects the machine's specs, registers it on Aptos, launches the renter's job in a Docker container with GPU passthrough, exposes a Jupyter notebook over a Cloudflare tunnel, and claims streaming payments on-chain while the job runs.

  4. 004RepoSynthPython / Rust / TypeScriptgithub.com/aniJani/reposynth

    A repository-understanding and retrieval platform. It fuses semantic search over SentenceTransformers/FAISS with lexical symbol matching, then feeds an LLM context engine over large codebases. A Rust tree-sitter parsing daemon with commit-keyed multi-stage caching cuts repeated re-analysis from 40s to 2s.

  1. PR #2522 · shipped in v0.9.36

    Graphify 104k stars · Python

    graphify cluster-only ignored the return value of to_json(), so when the shrink guard refused to overwrite graph.json the command still exited 0 and printed “updated” — leaving the report and labels describing a clustering the graph did not contain. Reordered the writes so the graph goes first, checked the refusal, and exited non-zero naming the untouched artifacts. Shipped with a regression test.

  2. PR #7818 · merged

    Scrapy 64k stars · Python

    Fixed a Python 3.14 forward-compatibility break — PEP 649 lazy annotations raising NameError during Scrapy's middleware and stats-collector introspection. Shipped a signature-inspection helper with regression tests, merged after maintainer review.
