Tools & technologies we work with
Core Pillars
360-degree expertise for your digital challenges
Four strategic areas of action to guarantee the security and performance of your digital assets.
Technical Sovereignty
Implementation of isolated work infrastructures (GitLab, Passbolt) to safeguard your intellectual property and access. No uncontrolled dependencies — you stay sovereign over your stack.
Protection & Anonymization
Implementation of Data Masking to transform real data into compliant and secure test sets. Every processing step is documented and GDPR-aligned, so innovation carries no legal risk.
Vendor Management
Technical supervision and auditing of external agencies to ensure delivered code quality and roadmap compliance. Your shield between your business goals and your technical deliverables.
Audit & Performance
Analysis of technical debt and architecture optimisation for fast, scalable, and sustainable web platforms. We identify what is slowing your growth and deliver a prioritised remediation plan.
Usecase #1
Large-Scale Data Migration & Inventory Restructuring
Ensuring a seamless transition to a new ERP ecosystem for industrial equipment.
The Challenge
A major industrial equipment manufacturer needed to migrate and restructure a complex database of over 100,000 product references and spare parts from a legacy system into a new management platform without data loss or operational downtime.
The Solution
Engineered custom PHP scripts for high-volume SQL data extraction and transformation, delivering a 100% successful migration within three months by coordinating technical requirements between internal IT departments and external software vendors.
Usecase #2
Digital Security & Infrastructure Audit
Ensuring compliance and performance for a multi-sector contract management system.
The Challenge
Our client needed to validate the security and efficiency of a proprietary contract management tool used to handle sensitive healthcare and social data, while ensuring strict compliance with data privacy regulations.
The Solution
Conducted a comprehensive four-week audit across 100 technical criteria, successfully identifying critical cybersecurity vulnerabilities and delivering a prioritized strategic roadmap to reinforce system performance and GDPR integrity.
Usecase #3
Custom Workspace Optimization Simulator
Empowering real estate advisors with data-driven office space modeling.
The Challenge
A global real estate consultancy needed an automated solution to help clients accurately estimate office space requirements by factoring in complex variables such as workforce size, hybrid work models, and specific activity ratios.
The Solution
Developed a full-stack digital simulator in five months — integrating a responsive frontend with a PHP-based lead management system — that captures client data, stores requests securely, and automatically generates personalized PDF assessments to facilitate strategic advisory meetings.
