Software development studio — Paris

Designing and building web and business applications, from architecture to production.

ArocLabs works with companies that need reliable, maintainable software: a web application, an internal tool, an API or the takeover of an existing codebase. One point of contact, from requirements to deployment.

The company

AROC LABS is a software development company founded in 2026 by Alan Queyroux, a full stack engineer with more than ten years of experience. It draws on work in the energy industry and in banking, and on running its own products in production every day.

Every project follows the same method: an explicit architecture, automated tests from day one, up-to-date documentation and frequent deliveries. Artificial intelligence is used as an engineering tool, where it brings a measurable benefit, and always under control.

What we do

Custom web applications

.NET APIs and Angular front ends, real-time features, authentication, payments, Azure hosting. From mock-up to production.

Business tools and desktop applications
