Summary
👤
Senior🎓
Top SchoolGabriel Tomitsuka is a Member of Technical Staff and chief architect-focused engineer with 11 years of experience building production-grade systems and early-stage AI products. He was the first technical hire at TextQL, where he leads development of an LLM engine, retrieval-augmented workflows, secure sandboxing, and performance/resilience work that drives accuracy in data-driven decisioning. A former founder and CEO, he raised angel funding and built an ML-powered recommendation engine for a consumer iOS product, blending product leadership with hands-on model fine-tuning and embedding work. Gabriel has repeatedly executed full-stack rewrites and cloud migrations—most notably scaling Contrary’s platform with Golang, React, Snowflake integrations, and higher conversion outcomes. Comfortable moving between research, infra and product, he combines startup grit with institutional experience from Deutsche Börse and a BSc in Computer Science from TUM. An early mover in AI documentation tooling, he focuses on reducing the marginal cost of data-driven decisions to near zero.
