The operational map
Your journeys, roles and business rules, especially the exceptions—because those are what cause projects to fail.
Business platforms
Complex web application development
Your current tool may no longer keep up, several applications may fail to communicate, or nobody may be able to say whether a new platform will support real demand. We design and build web platforms for serious business processes—systems that must connect to what already exists and evolve without interrupting operations.
From definition to production, working from Tarbes, Marrakech and Dover.
Contact usWho it is for
An application shaped around your operations
A complex web application is not simply an interface with many screens. It is a system of business rules that must remain correct, permissions that must stay watertight and data that must remain dependable while many people work at once.
We begin by understanding who does what, what moves through the organisation, what regulation requires and what already exists—not by choosing a technology.
- Your current tool holds you back more than it helps.
- You are launching a business platform that must still work in five years.
- You have several applications doing the same work repeatedly.
- You need to modernise without stopping production.
What we deliver
The interfaces
User workspaces, the administration console and operational dashboards.
Documented APIs
For exchanges with partners and your other applications.
The integrations
Existing systems, reference data and essential third-party services, connected progressively.
Data migration
Preparation, control and traceability for everything that has been transformed.
Documentation
Day-to-day operation and a structured handover to the teams taking ownership.
Architecture
Architecture, performance and security
We divide the application into domains with clear boundaries. A change to one module must not force changes across five others. That decision determines whether the platform will still be adaptable in three years.
Access rights, data protection, audit records and incident-recovery scenarios are designed from the outset.
Capacity decisions start from real usage: how many people act at the same time, when demand peaks and which operations they perform—not from theoretical sizing.
We also establish observability: traces that show exactly what happened and where when something goes wrong. Without it, diagnosing an incident becomes guesswork.
Modernisation
Modernise without breaking everything
Replacing an entire system in one move is the highest-risk scenario: everything changes on the same day, and operations stop if anything is missing.
When the current system remains essential, we proceed in parts. We isolate one domain, define exactly how old and new systems communicate, and replace first what creates the most value. Both coexist for as long as necessary.
Each stage produces a verifiable result and prepares the next.
How it works
Discovery
Your goals, users, constraints and unresolved decisions. Risks are identified while they are still inexpensive to address.
Definition
The scope, journeys, information model, integrations and target architecture.
Delivery
Increments you can see working. You validate continuously, not only at the end.
Launch
Data preparation, production readiness, team support and follow-through after launch.
What shapes the price
What determines the budget
We do not publish a list price because a business application is not a catalogue product. Two projects that look similar from a distance can differ fourfold in effort.
- The number of roles and distinct journeys.
- The depth of business rules and number of exceptions.
- The volume and sensitivity of your data.
- The number and condition of systems to integrate.
- Your availability requirements.
- The scale of migration from existing systems.
Discovery exists precisely to resolve these variables. It produces comparable options, explicit assumptions and a suitable delivery path.
Platforms delivered
Core Arena, an e-sports platform
Live broadcasting, tournaments and monetisation brought together in one web application. Live streams connect directly to tournaments, supported by a token system. React development, secured servers and managed operations.
“Good understanding of the project, a professional and versatile team.”
Courteasy, courtesy vehicles
A platform connecting garages and drivers, including professional-side rental management. Two user populations with different permissions. React and Node.js development, managed operations and maintenance.
“Noël is an excellent adviser and coordinator, available and attentive throughout the project.”
Questions
- When does a web application become complex?
- When several things must work together: distinct roles, numerous business rules, systems to connect, significant data volumes or demanding availability. Screen count is irrelevant. A ten-screen application may be far more complex than one with a hundred.
- Can you modernise without replacing everything?
- Yes, and it is often the right choice. We isolate domains, establish stable interfaces between old and new, and replace components in priority order while operations continue.
- How do you prepare for growth in usage?
- We start with your real usage: how many people, when, and performing which operations. We identify the first likely bottlenecks, adapt the architecture and then test under those conditions—not ideal ones.
- Are APIs and integrations documented?
- Yes. We document what each exchange expects and returns, how it behaves on error and what it depends on. This makes operation and future change substantially easier.
- How does an engagement begin?
- With a discovery workshop. We clarify goals, users, constraints, affected systems and unresolved decisions. You leave with a scope, a delivery path and enough information to decide whether to continue.
