THE STUDIO
SDO Studio is a human-sized studio, founded and run by Séléna D'Orion. No sales team, no subcontracting: one point of contact, from the idea to production.
Séléna founded SDO Studio after designing and building two complete platforms herself, both in production today with real users: Orion Universe, a multilingual international consultation platform with audio and video calls, per-minute billing and real-time translation, then Serena, a mobile app and an installable web app built from a single codebase.
These two products were not drawn for a brochure: they were built, published, tested by their users, corrected, then looked after day after day. That path — from the first idea to maintenance in production — is what shapes the way the studio works.
Scoping always comes first: your goals, your users, your constraints. Together we write down what the product must do — and what it will not do.
The person who listens to you is the one who designs the screens and writes the code. Nothing gets lost between a salesperson, a project manager and a developer.
Regular, testable versions, never a black box. You watch your product grow and you decide at every step.
Modular, documented, built to be taken over. What should stay adjustable is not hard-coded, and you own everything.
What is possible, what is not, what it costs and when. The studio prefers a clear answer to a convenient promise.
An application lives. Monitoring, fixes, new features: the studio stays alongside the product it built.
For a serious project, the question is not only "who will build it" but "who will understand it". In a human-sized studio, the person who heard your need on day one is the one who carries it to the last day: decisions stay consistent, deadlines are kept, and you always know who to talk to.
The studio therefore takes on only a small number of projects at a time, chosen so that each can receive that level of attention.
