You will get a custom AI agent system with FastAPI and Claude API
Top Rated
Project details
I build custom AI agent systems that make real decisions, use tools, and return structured outputs — not just chatbots that answer questions.
Every system I deliver is built directly with the Anthropic Claude or OpenAI API in Python, deployed to a live URL, and handed off with clean GitHub documentation. No no-code tools, no black boxes, no monthly SaaS dependencies.
My recent work includes a multi-agent research assistant that takes a user query, breaks it into search strategies, delegates to specialized agents, and returns a formatted research report in under 30 seconds — built with FastAPI, Tavily, and Claude, deployed to production.
What sets my work apart is systems thinking. I don't just write code — I design agent architectures that are reliable, maintainable, and built to grow. Every project includes clear documentation so your team can understand and extend the system without depending on me.
If you need a single focused agent, a multi-agent pipeline, or a full backend system with API endpoints — I can build it.

Steven was absolutely fantastic to work with. He completed very complex AI-assisted research for me in a timely manner and was meticulous about accuracy and very well organized. Highly recommended!

Job Success
Winchendon, United States - 5:13 pm local time
Typical builds:
• Open-quote / lead / request chase boards
• Client document checklists and missing-item tracking
• Simple staff or client status views
• Light automations and reminders so unfinished work does not die in an inbox
You work with one builder end to end. Fixed scope. Delivered in days, not months.
I run Clarwick. On Upwork I also offer a fixed Project Catalog install if you already know you need a follow-up board and want to hire without a long proposal thread.
Best fit: owners and operators at agencies, insurance, staffing, accounting, and other service businesses who are losing money to unfinished follow-up.
Not a fit: endless hourly ticket work, "make me an Uber," or speculative apps with no clear workflow.
100% Job Success. Top Rated. US-based.
