Technical design
Defining the architecture, components, flows, dependencies and technology choices to build a coherent, maintainable foundation suited to the project’s goals.

01 / Build — New projects
We design and build your application from a business need, specifications or a requirements document.
Defining the architecture, components, flows, dependencies and technology choices to build a coherent, maintainable foundation suited to the project’s goals.
Turning functional needs into concrete features, integrating them progressively and validating them iteration after iteration until go-live.
Translating business usage, constraints and priorities into relevant technical solutions, keeping a constant link between the project teams and the developers.

02 / Takeover & Migration
We audit and take charge of the existing code, architecture and technical environment to assess their quality, maintainability and risks before taking over their maintenance and evolution.
Analysing the project structure, code quality, dependencies, technical debt and sensitive areas to quickly understand what can be maintained, refactored or must be rebuilt.
Mapping components, their interactions, flows and dependencies to identify weak points, structural choices and possible obstacles to evolution.
Taking charge of the tools, configurations, development, deployment and production environments to secure the takeover and guarantee the project’s continuity.
Our AI tools speed up the analysis of a complete project and quickly produce indicators on structure, complexity, dependencies and technical debt. They complement our specialists’ analysis to help decide whether to maintain, refactor, modernise or rebuild.
A prepared takeover, to decide before committing to the rest of the project.
03 / Run — Maintenance & application maintenance
Third-party application maintenance supports the daily operation and continuous development of your application.
Anticipating anomalies, monitoring sensitive points and fixing identified defects to keep the application stable and reliable over time.
Supporting teams in analysing malfunctions, identifying their origin, implementing the necessary fixes and providing support until the service is fully restored.
Keeping application components, libraries and dependencies up to date to preserve the compatibility, security and stability of the environment.
Evolving the application over time by developing new uses, features and adaptations according to business needs and project priorities.


04 / Evolutions & Refactoring
Reducing technical debt and modernising components when your application needs it.
Restructuring and simplifying code to improve its readability, maintainability and robustness. As Code Gen becomes widespread, the topic becomes even more critical: poorly guided AI can quickly produce code that is hard to take over, making refactoring a growing challenge for the coming years.
Keeping components up to date, from minor versions to major upgrades. The latter can involve deep changes to frameworks, dependencies or architecture, and sometimes require a genuine application overhaul rather than a simple update.
Evolving components, frameworks or technologies when the existing ones become limiting, obsolete or too costly to maintain, by preparing a gradual, controlled transition.

05 / DevOps & go-live
The development and managed services teams work together to prepare environments, secure deployments and ensure continuity between Build and Run.
Structuring the development, testing, pre-production and production environments, with consistent, controlled configurations at every stage of the project.
Preparing, automating and executing go-lives in coordination with the managed services teams, to limit risks and service interruptions.
Organising the move of changes into production and gradually handing over operations to the managed services teams, to ensure continuity between development, go-live and daily maintenance.
A natural continuity with Pilot Systems’ Cloud and managed services skills.
