About Jacob Sapir

Senior AI backend and agent engineer behind Real Technology Tools.

Jacob Sapir

With 10+ years in software engineering, I help founders and product teams build and ship production AI systems. My work covers AI backends, LLM applications, agents, APIs, RAG, and evaluation.

Why the safety-critical background matters

Before specializing in AI, I worked on safety-critical automotive and aerospace software, including projects related to autonomous driving, aerospace engineering, and armored vehicle manufacturing. That background shapes how I build AI systems today: with an emphasis on reliability, testing, clear interfaces, and failure modes.

How I collaborate

I work directly with founders and product leaders. I communicate clearly about tradeoffs and architecture, and I stay hands-on in the implementation. The goal is straightforward: ship AI systems that are useful, maintainable, and dependable in production.
