Fractional CTO · Applied NLP · Orlando, FL
Production engineering for language-driven systems
Software 407 is an independent engineering company helping startups grow their technical foundations.
I build and operate the backend behind AI products: retrieval, evaluation, and the checks that keep a
model truthful and reliable in production.
AI and language systems are my specialty, but my role is broader: the senior
engineering leadership your team needs before it can hire a full-time CTO. You work
directly with the engineer doing the work.

About
Adrien David
For the last decade I've worked on systems that use natural language as an interface:
reading and responding to guest messages, retrieving the right support answer, conducting voice interviews,
and verifying what a model claims. I was the sole technical owner of Hostvana's
platform for six years, shipped a semantic search engine at LivePerson, and now lead
the grounded-factuality work at Labstr.
I trained as an engineer at École des Mines in France and am based in Orlando.
I founded Software 407 LLC in 2024 to give my independent work a home.
