AI Systems Architect | Workflow Automation for Business Owners

Wesley Chapel, United States - 11:48 pm local time
I build private AI systems that replace high-friction manual workflows, one process at a time, in 2-4 week sprints. If you run a business with 5-50 people and your team is still copying data between systems, sorting requests by hand, or manually processing documents, I design and deliver AI systems that handle it reliably, privately, and at a fraction of the cost of hiring more people.

This isn't prompt engineering or generic chatbot work. I architect end-to-end AI systems: document intelligence pipelines, automated sorting and routing, AI-assisted data extraction, knowledge retrieval systems, and agent-driven workflows. Built to production standards with real engineering behind them.

What a typical engagement looks like:
We identify the single highest-friction workflow in your operation. I scope it, architect the AI solution, build it in a focused 2-4 week sprint, and hand you a working system your team can trust. Then we move to the next one.

Why clients hire me over other AI freelancers:
→ 20+ years of production engineering, including 4 years at Apple and enterprise work at Yahoo, Thomson Reuters and Citibank
→ Technical reviewer for Manning Publications ("Modern Java in Action")
→ Expert-Vetted on Upwork (top 1%), 100% Job Success, $200K+ earned
→ I've built AI-powered document processing, OCR extraction, and LLM integration in real production systems, not demos
→ I think like a business owner because I am one (founded and ran a 30-person software company)

Recent AI systems I've built:
- AI-powered loan processing system with document intelligence, OCR, and automated data extraction (Azure AI + OpenAI)
- Internal AI workflow orchestration, routing tasks across planning, development, QA, and DevOps agents
- Automated lead scoring and routing systems
- Knowledge retrieval systems for internal operations
- AI-assisted weekly reporting pipelines

Fixed-price sprint packages available for clearly scoped workflows. Let's talk about the one process that's costing you the most time.

P.S. I'm not a good fit for task-only, hourly-grind, or price-driven work. I work best with business owners who want a real results and systems, not a science project.
