What I build
One counterpart. A complete product.
Not a 40-person agency. Senior expertise to design, build and ship.
Orientation
Which solution do you need?
Pick your goal. I will point you to the right kind of project — without the jargon.
Work
A few products in production.
Real products, in different industries. Some were built as a team: I then specify what I actually built.
Experience
The long missions, beside the case studies.
The work shows shipped products. This is the thread of roles, clients and training that actually lasted.
Expertise
A stack chosen for the product, not the other way around.

- Java
- Spring Boot
- Spring Security
- Hibernate / JPA
- REST APIs
Frontend
- React
- Next.js
- Angular

The studio
+6
years turning business needs into reliable products.
YSAA is not a forty-person agency. It is an independent studio: I design, build and ship websites, stores, applications and automations, without handing you from salesperson to salesperson.
We start from the real need — sell, recruit, operate, automate — then we build the right solution. No imposed stack, no throwaway demo.
Trained at Alyra in blockchain fundamentals, I also want to bring this product and full-stack expertise to useful Web3 projects.
01
One counterpart
From scoping to production, you talk to the person who builds.
02
Frontend + backend
I can work on a complete product, not only a landing page.
03
Enterprise experience
Used to professional projects and demanding environments.
04
Product before technology
Technical choices follow the need. Not the other way around.
05
Takeover capability
I can also work on an application that already exists, even an imperfect one.
Process
From idea to production.
- 01
Understand
Goals, users, constraints. Before writing a line.
- 02
Design
Architecture, UX, UI. A clear direction, not a throwaway prototype.
- 03
Build
Product, frontend, backend, integrations.
- 04
Test & ship
Tests, optimisation, infrastructure, go-live.
- 05
Evolve
Maintenance and new features, without breaking everything.
Questions
Questions that help you decide.
+How much does a website cost?
A refined landing page and an institutional CMS site are not in the same envelope. The project assistant is there to frame a realistic scope. A precise quote comes after a conversation.
+How much does an application cost?
A business app or SaaS depends on roles, integrations and admin depth. We often start with a useful MVP, then extend. No magic price from a form.
+Can the project evolve later?
Yes. Architecture is designed to grow: new pages, new roles, a new channel (PWA, API) without rewriting everything.
+Can you take over an existing project?
Yes. Bugs, blocked production, inherited code, a developer who left: this is an explicit offer. I analyse what exists before proposing a takeover or a migration.
+Do you only work in Nantes?
I am based in Nantes, and I also work fully remotely across France.
+Can you handle hosting?
Yes, as part of taking the product to production: VPS, Docker, HTTPS, CI/CD. I do not sell hosting by the gigabyte.
+Web app or mobile app?
If the need mostly lives in a browser, a web app is often enough. Native mobile is justified when the store, deep offline use or device hardware (camera, scan) are central.
+Do I need a native app, or is a PWA enough?
A PWA lets people install the product on a phone without going through the stores immediately. That is often the right first step. Native comes later if constraints require it.
+Can you add AI to my company?
Yes, preferably on a precise manual process (documents, qualification, summaries). No need to rebuild the whole application. The AI sprint starts at €1,500.
+Do you work with companies that already have a technical team?
Yes. Java/Spring backend support, APIs, takeover, or a precise module. I join what exists rather than replacing everything.
