About this gig

I'm a principal software engineer with 12 years in production. I build AI agents that call your APIs, read your documents and run on your cloud or on local models.


Recent work:

  • An AI matchmaking agent on ElizaOS that runs over WhatsApp
  • The transcript analysis pipeline behind Napster's AI shopping agent (FastAPI, Celery, Gemini)
  • The MCP endpoint for Companion Hub, a self-hosted runtime for apps, models and agents


What I can build:

  • An agent with tools that call your APIs, databases or SaaS accounts
  • Retrieval (RAG) over your PDFs, docs or website
  • Agents on OpenAI, Anthropic or Gemini, or on local models through Ollama
  • Agents that talk to users on WhatsApp, Discord or your website
  • A FastAPI or Node.js backend and React front end around the agent
  • Deployment on AWS, GCP, Azure or Cloudflare with Docker


You keep the code and your API keys. Please message me before ordering so we can agree on scope.

Principal software engineer with 12 years in production, remote with US companies since 2021. I build AI agents and MCP servers, plus the backends around them: FastAPI, Node.js, React, single sign-on and Stripe billing on AWS, GCP, Azure or Cloudflare. Recent work includes the MCP endpoint for Companion Hub, an AI matchmaking agent on ElizaOS and Napster's single sign-on for Napster AI, Napster Music and Napster Spaces. From 2021 to 2024 I was an engineering manager on the open-source Ethereal Engine. I started at Bentley Systems in 2014.
