Product engineering
Web platforms, dashboards and SaaS products engineered to scale, from zero to one and beyond.
Studio · Open for Q3 / Q4 2026
Software, engineered
like it matters.
Perceptrondev is a small senior team designing and shipping serious web, AI and platform software. No agency theatre — just engineers and designers who care about the second year of the product as much as the first launch.

§1 — Services
A small studio with a wide stack.
We don't separate "design" and "engineering" into stages. The same senior people own the product from sketch to deploy.
02↗
AI & data systems
LLM pipelines, retrieval, evaluation, agents — shipped into production with the rigor of real software.
03↗
Design systems
Tokens, components, motion. Interfaces that hold up after the fifth feature, not just the first demo.
04↗
Platform & infra
Edge runtimes, observability, CI/CD. Boring on purpose, so the product stays interesting.

§3 — How we work
Senior people, short loops, real shipping cadence.
01 / Frame
Understand the system
We map the product, the constraints, and the people. Two weeks, one document, zero hand-waving.
02 / Build
Ship every week
Small senior team, weekly demos, production from week three. No long invisible phases.
03 / Operate
Stay accountable
Observability, on-call, iteration. We measure the second year of the product, not just launch day.
§4 — Studio
A studio of
engineers, first.
Perceptrondev was started by senior product engineers who wanted to build software the way they wished it had been built for them — small teams, real ownership, no theatre. Eight people, between Paris and remote.
01
Senior or nothing
Every person who touches your code has shipped real systems. No staffing pyramid, no juniors learning on your bill.
02
Engineering is a craft
We write tests, document interfaces, run CI seriously. The unglamorous work is what makes software last.
03
Design is structural
Interface decisions shape the engineering. Designers and engineers sit in the same room — usually the same brain.
04
Own the second year
Anyone can ship a launch. We optimise for the version of the product you'll still be proud of in two years.
§5 — Contact
Let's talk about
the project.
We respond within two working days. If we're a fit we'll suggest a 45-minute call to scope the work.
