Summary
AI engineer and senior full stack engineer with 9+ years of experience and a year of production LangChain/LangGraph agentic systems shipped to paying users. Built multi-tool LLM workflows on Azure OpenAI with Pinecone hybrid retrieval, token budgeting, streaming, and human-in-the-loop drafting — across a FastAPI backend, a React/TypeScript web app, and a React Native iOS client.
Experience
VeteranAI — Senior Full Stack Engineer
Feb 2025 – May 2026 · Remote
- Built an agentic claims assistant (LangChain/LangGraph, Azure OpenAI, Pinecone hybrid retrieval) with 18+ tools over medical literature, the M-21 manual, and 38 CFR — drafting personal and buddy statements and nexus letters; ~60% faster time to draft.
- VA.gov dual-OAuth integration (benefit-claims + veteran-verification); Form 21-0966 and 21-526EZ submission flows.
- Stripe + RevenueCat StoreKit 2 monetization with idempotent webhook reconciliation; Apple 3.1.1/3.1.2 compliant; subscription drift cut to near zero.
- Shipped across 3 codebases / 500+ commits: FastAPI, React 18 + TypeScript (Vercel), React Native 0.84 (TestFlight). AWS ECS Fargate/S3/Textract/CloudWatch, Celery/Redis, FCM, GitHub Actions.
- Aurora Night — my own React Native design system, a look inspired by iOS 26 Liquid Glass: 36 components and 18 screens on Reanimated v4; on device speech to text and text to speech for accessibility.

I ship production agentic AI to paying users — and the full stack underneath it.

Watch Kairos reason.
The run below is real orchestration — pick a job and watch Kairos plan, call tools, hit one failure, recover, and finish. It plays once; replay or switch anytime.

// 03 · the_graph
Eighteen tools, one orchestrator.
Every tool Kairos can call, wired to the systems it works against. Hover any node to trace its data path; the rest dims so the wiring stays clean.

The design system is mine.
The glass, the motion, the component language here come from Aurora Night — my own design system, built from scratch with no UI kit. The look is inspired by iOS 26 Liquid Glass; the engineering is mine: 36 components across 18 screens on Reanimated v4. This site is the work sample.
Flip the switch — the card responds the way it does on a real device.
I built the glass surface, the specular rim, the animated background, the custom tab bar, and a gesture-driven severity slider from scratch — no third-party UI kit. On-device speech-to-text and text-to-speech made it usable hands-free, at zero per-request API cost.

Not buzzwords — the stack behind production software with paying users, grouped by what it shipped.
// 06 · run_history
A track record, read like a deploy log.
Every entry shipped. The current role is detailed above; expand any other to see what it shipped.
- Agentic claims assistant. Designed and shipped LangChain/LangGraph workflows on Azure OpenAI and Pinecone hybrid retrieval, with 18+ tools over medical literature, the M-21 manual, and 38 CFR — drafting personal statements, buddy statements, and nexus letters. ~60% faster time to draft.
- VA.gov dual-OAuth integration. Two OAuth flows (benefit-claims + veteran-verification) with different scopes and token lifetimes, async ratings/service-history polling, and full Form 21-0966 + 21-526EZ submission paths.
- Production monetization. Stripe Checkout (web) + RevenueCat StoreKit 2 IAP (iOS) with idempotent webhook reconciliation — Apple 3.1.1/3.1.2 compliant, subscription drift cut to near zero.
- Three codebases, 500+ commits. FastAPI backend, React 18 + TS web on Vercel, React Native 0.84 iOS app on TestFlight. AWS ECS Fargate / S3 / Textract / CloudWatch, Celery + Redis, FCM, GitHub Actions CI/CD.

Off the clock.
Before software, the Navy taught me to finish hard things under pressure.
A thousand rounds on the jiu-jitsu mat taught me the same lesson software keeps teaching: stay calm, keep working the problem, and don't tap until it's done.
That's where the code comes from — systems people lean on when the stakes are real.
