Jérôme Velociter
I build and ship software alongside startup teams, from early product conversations onward.
Selected works
BiomeOS

Range
Software rarely stays in one lane.
Since 2006, I’ve worked across software products, data and infrastructure, systems that control physical machines, and the teams building them. I’m at home in each of these areas, and especially useful when a project spans more than one. I bring product judgment as much as code.
Product engineering
Turning product ideas into reliable software, from early decisions to launch and continued evolution.
Data & infrastructure
Data collection and infrastructure with the observability needed to keep systems understandable and reliable.
Machines & field systems
Software bridging IT and OT, from controlling and monitoring equipment in the field to integrating it with cloud services.
Teams & direction
Setting technical direction, shaping roadmaps, and hiring and coaching teams while keeping delivery moving.
Reach out
Working on an ambitious software product?
I work alongside startup teams, building the product and leading the technical work when needed. Depending on the role, I can join full-time, part-time, or as a fractional CTO.
I’m based in Toulouse and available for regular travel to Paris, London, Amsterdam, and a few other cities.
I usually reply within 2 business days.
