I will build ai agents and workflow automation for your business


About this gig
Tired of repetitive work slowing your team down? I build AI agents, chatbots, and workflow automation that handle the busywork for you.
At Optum (UnitedHealth Group), I built AI systems used daily in production:
- A RAG system that recommends medical codes from documents, used by 300+ coders, with 85% of suggestions accepted and 35% less manual work
- Automation that handles 65% of prior-authorization requests, cutting turnaround from 72 hours to under 24
What I can build for you:
- AI chatbots that answer questions from your own documents, website, or database (RAG)
- AI agents that complete multi-step tasks across your tools
- Workflow automation connecting your apps, CRMs, APIs, and databases
- AI features for your product, with validation and human review so mistakes don't reach customers
Tools: Python, Node.js, TypeScript, LangChain, LangGraph, AWS Bedrock, OpenSearch, PostgreSQL
Why work with me:
- 6+ years building production systems, not just demos
- Clear communication and honest estimates
- Clean, documented code you fully own
Message me before ordering with what you'd like to automate, and I'll suggest the simplest solution that works.
