About this gig

Not a chatbot. An agent that actually does things.


I build autonomous AI agents that take a goal and execute it searching the web, reading documents, writing files, calling APIs, and making decisions without you having to babysit it.


Built with LangChain, CrewAI, and Claude or GPT-4. Delivered as clean Python code you can run on any server.


WHAT I BUILD:

- Research agents (web search summarize report)

- Sales outreach agents (find leads enrich draft emails)

- Customer support agents with escalation routing

- Data analysis agents (CSV insights formatted output)

- Multi-agent pipelines (researcher + analyst + writer working in parallel)

- n8n AI agents with Claude tool-calling and memory

- Document processing agents (PDF/Word structured data)

- Code review agents with GitHub integration


EVERY DELIVERY INCLUDES:

- Full Python source code

- Memory layer so the agent remembers context

- Error handling and retry logic

- Setup guide and usage documentation

- 7 days of post-delivery support

- 2 rounds of revisions


Tell me what you want automated and I'll tell you exactly which agent architecture fits best.
