What I Do

AI & LLM Integration

Multi-agent orchestration with LangGraph. Claude, GPT, Perplexity: matched to the task. Production systems, not prototypes.

Full-Stack Development

React, Svelte, Swift on the frontend. Python, TypeScript, Node on the backend. I build the whole thing.

Cloud & Infrastructure

AWS, Cloudflare, Fly.io, Vercel. CI/CD, Docker, cost optimization. The boring stuff that keeps systems running.

Workflow Automation

Find the repetitive work killing your team's time. Automate it. Ship it. Move on.

Tech Stack

Frontend React, Svelte, SvelteKit, Swift/SwiftUI, TypeScript
Backend Python, Node.js, Fastify, GraphQL, PostgreSQL, Hasura
AI/ML LangGraph, Claude API, Perplexity, OpenAI Whisper, Vision Transformers
Infrastructure AWS, Cloudflare, Fly.io, Vercel, Docker

Why Me

15+ years shipping production software. Former CTO. Founded and exited a profitable consultancy. Led technical programs for Home Depot, Thermo Fisher, P&G.

Currently building CapCheck: multi-agent LLM pipelines processing real-time fact verification. I know what breaks because I'm breaking it right now.

How It Works

1

Discovery Call

30 minutes. You tell me what's broken or what you want to build. I tell you if I can help.

2

Scoped Engagement

Fixed scope. Fixed timeline. No open-ended retainers. Typical projects run 2-6 weeks.

3

Delivered & Documented

You get working systems, not slide decks. Full documentation so your team can maintain it.

Let's Talk

One project at a time. Limited availability.
