What I help with
I take technical ownership of LLM-powered products (agents, backends, integrations, and the reliability work that makes them usable in production).
AI agents & workflows
Tool calling, multi-step agents, and orchestration that stays predictable under real product constraints.
LLM backends & APIs
Python/FastAPI systems, structured outputs, and integrations that other services can depend on.
Production hardening
Validation, retries and fallbacks, logging, evaluation, and cloud deployment for systems that must keep working.
How engagement usually works
- An initial discovery call covering goals, constraints, and fit.
- Hands-on technical ownership spanning architecture, implementation, integration, and production trustworthiness.
- Direct collaboration with the senior engineer doing the work (not an anonymous delivery bench).
About Jacob
I’m a senior AI backend and agent engineer. Earlier experience in safety-critical automotive and aerospace software shapes how I build: clear interfaces, tested behavior, and attention to failure modes.
Real Technology Tools is the professional vehicle for this work, a direct path to collaborate on production AI systems.
