I’m a distributed systems engineer building real-time payments infrastructure at Root, where I was the first engineer. Before that I was a founding engineer at Gamma (acquired by Palo Alto Networks). In the past I’ve also done research on reconstructing what people see from brain activity, and co-authored MindEye2 (ICML 2024). Lately I’m building Weft, a small platform for fine-tuning and serving open models.
Outside of work I boulder and watch a lot of movies. I also keep a bookshelf of what I’ve been reading.
Now
- Root Payments platform, durable transfers, public API, a fine-tuned model for bank files
- Weft A small Tinker-style platform for fine-tuning and serving open models, built in public

Distributed systems notes
Durable workflows, deployments and API design, worked through on a made-up payouts company.
- 01 Moving money when the bank times out Drafting
- 02 Rainbow deployments for Temporal workers Soon
- 03 API versioning at the edge Soon
- 04 A small model for bank statement files Soon
Building Weft
Notes from building a multi-tenant training and serving platform, one block at a time.
- 01 Multi-tenant training on one base model Soon
- 02 Serving many LoRA adapters at once Soon
- 03 Durable job orchestration Soon
