Data Systems Engineer
I build production software that companies run every day.
Two of mine are in daily production at a large multi-state retailer: the pipeline behind its competitive pricing, and the system its warehouse runs to ship product. I build with that same rigor for founders who need something shipped, and I move quickly.

Work
The data pipeline behind a large retailer's competitive pricing. It reverse-engineers three protected retail APIs sitting behind Cloudflare and auth, runs a BullMQ and Redis worker fleet, normalizes 130,000+ products across 31 chains in 14 states into Postgres, and runs OCR on promo images. Behind 790 tests. A pricing team has relied on it daily for over a year, and it replaced roughly two weeks of manual work every cycle.
The system a warehouse runs to get product out the door. Staff scan a barcode, it looks the item up across every source, and it prints a clean thermal label on Zebra hardware with the product, batch, dates, allergen flags, and box tracking. Multi-file CSV and Excel import, a cloud-synced master catalog, and an offline mode for when the network drops. Every box that ships carries a label it printed. Running live since 2024, now on its seventh major version.
Autonomous AI agents, Claude and Codex, that play full video games start to finish with no human in the loop. They run on vision plus RAM-state perception, an objective director, and a long-horizon control loop, and will run for hours unattended while you watch live. They have beaten Pokemon end to end, including the postgame superboss.
The rest of my code is public on GitHub. It is a lot, and it is clean.

Working with Clayton has been one of the best contracting experiences I've ever had. His engineering was absolutely excellent, but honestly, it's the character alongside it that really stood out. The work he delivered was phenomenal and genuinely turned out better than I had even imagined. His efficiency was unmatched, there was never a single delay in any aspect of the entire project. It is rare to find someone who pairs elite technical skill with such high integrity and professionalism. I cannot recommend him highly enough.
Clayton is an exceptional developer. His communication was highly professional, his documentation was flawless, and the entire hand-off process was completely seamless. Highly recommended for any complex data science or software engineering needs.
Clayton did outstanding work. His work was accurate and his response times were very fast. His assumptions and findings were clearly stated and easy to follow. He also contributed an unexpected value add to this project that far exceeded expectations. Well done, Clayton.
