About

I'm Ruoqi Jin. I build deterministic compiler backends to cure LLM hallucinations. S-expr → Typed IR → Rust.

What I Do

• Creator of Neural-Codegen — a neuro-symbolic architecture that constrains LLMs to output S-expressions, validates against typed IR, and deterministically assembles guaranteed-compilable Rust code
• Founder of XiaojinPro — AI-powered next-generation video editing platform built with Rust

Background

• 13 years in the film industry — from on-set DIT to color suite, deeply involved in film, commercial, and documentary production
• Systems programmer — Rust, TypeScript, Lisp, Swift, Python
• Harness engineer — the moat in agentic software development is the harness, not the model
