Currently

Granted Healthfounding team · staff engineer · 2025–now

I designed and lead the agent platform that resolves medical-billing disputes for patients: long-running multi-agent workflows with explicit state, human-in-the-loop approvals, durable execution on Temporal, and evals. The product's AI-driven workflows run through it.

Work

Production AI since 2022, the last three years in healthcare: voice agents, RAG, multi-agent automation. Before that, a decade shipping full-stack products.

Assort Health

2023–24

Founding engineer on a voice-AI contact-center platform for healthcare. Shipped intent routing that lifted automation from 70% to 85%, and ran infra for thousands of concurrent LLM patient calls.

Senior engineer on a disinformation-detection platform. Built the company's first LLM integration in under a month, demoed during the raise. Cut network-viz generation time by more than half.

Side projects

DreamDraft

● live

AI children's-book creator. Fine-tunes Stable Diffusion on a family's own photos so the kid is the hero of the story.

The hard part was making personalized image generation reliable enough for non-technical parents.

Pixelbench

○ building

Evaluation and monitoring for text-to-image models: measure quality, compare models, catch regressions.

Turning subjective image quality into numbers a team can act on is the whole problem.

03

Writing

From one prompt to a planner/executor split, a context registry, an event-sourced fact store, and evals that boot the real graph. Each piece exists because something broke without it.

Reading notes: what each paper changed in the agent platform, not a canon.

Contact

Open to staff and founding roles building agent systems.
