Development and integration of customized software solutions.

A traditional software publisher designs a standard product for a broad market, covering generic needs but often requiring you to modify your processes in order to adopt it. Conversely, an editor/integrator like IT Systèmes develops software specifically designed for your business uses, and ensures seamless integration into your existing information system. This means you benefit from a single solution, tailored to your organization, connected to your existing tools (ERP, CRM, EDM, databases, SaaS) and designed to evolve in line with your needs.

The success of a development project depends not only on the technology chosen, but above all on its ability to respond precisely to business needs. All too often, standard solutions require internal processes to be modified to fit the tool, generating inefficiencies, frustration and hidden costs.

At IT Systèmes, we adopt a business-first approach:

• We organize scoping workshops with your teams to understand your processes, regulatory constraints and strategic objectives.
• We translate these needs into clear technical specifications, prioritizing the functionalities that bring the most value.
• Our developments are designed according to SOLID principles, guaranteeing modular, tested and scalable software, but always aligned with your business challenges.

By starting with the business, we can create software that perfectly matches your needs, encourages user adoption, improves productivity and reduces adaptation costs. It's also the best way to ensure that technology remains a performance gas pedal and not a business inhibitor.

We master all modern and legacy languages, frameworks and environments, enabling us to work on all types of projects, from backend and frontend development to integration and automation:

• Backend & system languages: Java, Kotlin, Python, C#, C++, PHP, PowerShell, Shell Script
• Frontend & mobile languages: JavaScript, TypeScript, Swift, HTML5/CSS3
• Frameworks & libraries: ReactJS, NextJS, VueJS
• Databases: SQL Server, Oracle, MySQL, PostgreSQL, MongoDB, NoSQL
• Integration & APIs: REST, GraphQL, SOAP, API Management, RPA via FlexFlow
• Cloud & SaaS ecosystems: Microsoft Azure / 365, AWS, Google Cloud, Oracle, Salesforce, SAP

This technological versatility enables us to select the best combination according to your business needs and constraints, rather than locking you into a single solution. It also guarantees the durability and scalability of your applications, ensuring their compatibility with current and future environments.

The duration depends on the complexity of the project. A simple application can be delivered in 6 to 8 weeks, whereas a complex tool requiring several integrations (ERP, CRM, EDM, SaaS databases) can take several months. Thanks to our Agile methodology, we deliver usable intermediate versions at each sprint (2 to 3 weeks). This enables you to benefit rapidly from the first functionalities, to involve your users in the tests and to generate a progressive ROI from the very first phases.

Security is integrated right from the first sprint, in a DevSecOps approach. In concrete terms, we integrate automated controls into our development pipelines:

• systematic flow encryption (TLS, HTTPS),
• strong authentication (MFA, SSO, Azure AD, OAuth2),
• centralized management of user access and rights,
• ongoing vulnerability scans and security tests,
• audit logs and full traceability;

Our software complies with current regulations: RGPD for personal data management and ISO 27001 for information systems security.

UI (user interface) and UX (user experience) are often underestimated, even though they represent a key success factor for any project. An application that is technically powerful but poorly designed in terms of ergonomics will not be adopted by users, and will generate rejection or high support costs.

At IT Systèmes, we integrate UI/UX right from the start of a project, as part of our Agile approach. In concrete terms, this means :

• Design thinking workshops with your business teams to identify priority career paths.
• Mock-up and prototyping before each sprint to validate screens and interactions.
• Regular user testing to adjust interfaces according to feedback.
• Accessibility and responsive design to guarantee an optimal experience on all terminals (PC, tablet, mobile).

Good ergonomics are about more than aesthetics: they improve user productivity, reduce training time and errors, and speed up the adoption of new solutions. In other words, investing in UI/UX ensures the operational success of your project.

Many legacy or business applications lack modern APIs. We use our FlexFlow platform, which enables us to automate exchanges via specific connectors or Robotic Process Automation (RPA). In concrete terms, this means we can simulate human actions (clicks, inputs, extractions) or develop ad hoc connectors to link these software applications to your IS. In this way, even your oldest tools become interoperable without having to be replaced.

Technical debt is a major risk for any IT project. To avoid it, we rigorously apply the SOLID principles, which make code modular, testable and scalable. Each component is isolated, so it can be upgraded without impacting the whole. We also practice automated testing (unit, integration, end-to-end) and document each sprint. This approach guarantees high-quality, maintainable code capable of supporting future evolutions.

Yes, we offer a complete TMA (Third Party Application Maintenance) service, covering :

• correction of anomalies,
• regular updating of dependencies and security patches,
• functional evolution with the addition of new features,
• proactive supervision and user support.
  This guarantees the durability, performance and security of your applications over the long term, while supporting your company's growth.

When you choose IT Systèmes as your editor/integrator, you benefit from :

• Applications that reflect your business processes.
• Reduced costs by integrating existing tools rather than replacing them altogether.
• Total IS interoperability, even with legacy software.
• Secure software that complies with RGPD and ISO 27001 standards.
• Rapid adoption thanks to UX/UI interfaces designed with your users and validated at each sprint.
• A future-proof, scalable system, capable of adapting to your future needs without technical debt.
