About Pierre-Hubert

Full-stack software engineer, from product to technical. I help companies, startups, and app creators design, build, fix, or evolve their products: mobile applications, APIs, backends, automation, dashboards, and internal tools.

I had an entrepreneurial adventure by creating and publishing Pig Jump, a mobile game on iOS and Android. I managed the entire product, from vision to launch: mobile client, custom backend, database, hosting, in-app purchases, store publication, internal tools, and automated reporting. This was an opportunity to lead a product end-to-end, autonomously.

Before development, I was a financial engineer / pricer / structurer in front-office (Société Générale, New York). I retain a rigor for business logic and critical environments where a mistake is costly, which can be useful for banking, fintech, or insurance projects.

What I try to bring, beyond technical execution: understanding the business need behind the request, who uses the tool, what decision it serves, what benefit it provides.

I am comfortable with concrete missions: taking over and stabilizing an existing application, fixing a backend or mobile problem, creating an API, unblocking a store publication, automating reporting, or setting up a dashboard or an internal tool.

I work primarily remotely, with a pragmatic approach: understand the need, clarify the scope, and deliver something reliable and documented.
