I do computer vision, LLM pipelines, edge AI, and NLP. Lately I’ve been doing weld detection on fuel pipelines, tracking aircraft from a Raspberry Pi, and building a local OCR app that runs entirely on-device. I also build my own products on the side.

Selected Work

Weld Detection for a National Pipeline Operator

Computer Vision / Non-Destructive Testing

Full CV pipeline for detecting welds in pipeline inspection data. Built it from scratch, then found a position-dependent sensor bias hiding in the data that nobody had noticed before. This runs on critical infrastructure — fuel pipelines across the country.

YOLO Signal Processing Python

Aerial Object Detection & Geolocation

Edge AI / Embedded Systems

Raspberry Pi + Hailo NPU that detects aircraft, locks a gimbal onto them, measures distance with a laser, fuses ADS-B transponder data, and calculates GPS coordinates. All real-time, all on edge.

Hailo NPU YOLOX Kalman Filter Raspberry Pi

Enterprise Document Management Platform

Full-Stack / Security

30+ page platform with ABAC policy engine, hash-chain audit trails, and mindmap document views. Built the compliance architecture from scratch because the off-the-shelf options couldn’t handle classification levels properly.

Next.js Postgres ABAC

Named Entity Recognition on Government Documents

NLP / Information Extraction

Person extraction from 128 Polish regulatory PDFs. Tested 46 LLMs through a unified evaluation pipeline, then wrote preprocessing that shrank each file enough for near-free inference. The hard part was picking the right model, not running it.

NER LLM Evaluation Python

Products I’m Building

Hardparse

Local-First OCR for macOS

On-device OCR that runs a vision-language model entirely on your Mac. Tables, formulas, charts, seals. Fully offline — your data never leaves the machine.

Swift MLX CoreML Metal

CodeSOTA

ML Benchmark Tracker

Independent benchmark tracking across 17 ML research areas with 286+ verified results and implementation links.

Next.js Postgres Vercel

TasteRay

AI Movie Recommendations

Conversational recommendation engine that builds a taste profile through dialogue — context-aware picks, not just collaborative filtering.

Next.js Cloudflare Workers
