AI engineering for products that ship

I’m a senior AI backend and agent engineer. I take technical ownership of LLM-powered products — agents, backends, integrations, and the reliability work that makes them usable in production.

Earlier experience in safety-critical automotive and aerospace software shapes how I build: clear interfaces, tested behavior, and attention to failure modes.

What I help with:

  • AI agents and workflows — tool calling, multi-step agents, reliable orchestration
  • LLM backends and APIs — Python/FastAPI systems, integrations, structured outputs
  • RAG and knowledge systems — retrieval, grounding, evaluation
  • Production hardening — validation, retries and fallbacks, logging, evals, cloud deployment

What I bring:

  • Agents, tool calling, and context engineering for real product workflows
  • Production LLM applications on Python and FastAPI (OpenAI, Claude, Gemini)
  • RAG, structured outputs, and evaluation / reliability tooling
  • Conversational and voice AI when the product needs it
  • AWS/cloud deployment, CI/CD, and production troubleshooting

Client feedback

“Though he was hired specifically as a prompt engineer, his technical skills were advanced enough that he made contributions to other aspects of our development. All-in-all our experience with Jacob was stellar and we won’t hesitate to ask him to augment our team again should the need arise.”

Excited to work together? Here’s what you can expect:

  • An initial discovery call — we’ll discuss your goals and constraints and see if we’re a good fit.
  • Hands-on technical ownership — architecture, implementation, integration, and making the system trustworthy in production.

If we’re a fit, email contact@realtechnologytools.com to get started.
