I will build a production ai agent or rag system for your product
Jacob Ralph
About this gig
Most AI features work in a demo and break in production. I build agents and RAG systems that hold up with real users, real data and real costs.
I'm a fractional CTO and AI systems architect with 15+ years shipping production SaaS. As FancyAI's co-founder and CTO, I led the technology behind FancyGEO, an AI visibility platform: a dual Claude + GPT engine on a research corpus of 40,000+ websites and 1,500+ sources, with 50+ paying customers and under 3% monthly churn.
Recent builds:
- An event-driven AI CRM: 41 workflows orchestrating 39 specialized agents, with a human review queue on every outbound draft. In active production use.
- A multi-agent engineering system that turns specs into tested code, validated by 725+ tests.
What you get:
- Retrieval, prompts and tools designed around your data, not a generic template
- Evals so you can see quality instead of guessing
- Cost and latency controls from day one
- Clean Python or Node.js code, deployed on AWS, with documentation
Not sure which package fits? Send me a message with what you're building and I'll tell you.

You get a fractional CTO who also builds, so the person who makes your technical calls ships them. 15+ years in production software; as co-founder and CTO I built an AI platform from zero to 50+ companies with under 3% churn.
Start with an MVP, AI for work your team repeats, an audit or a rescue. I scope it and deliver in milestones you accept in writing, and can stay on as your technical lead after.
Discovery comes first. Anything that fails the agreed test within 30 days of acceptance, I fix at no extra charge.
