Privacy, quality and clear documentation
European teams tell us they want a partner who treats data protection and quality as the starting point, not an add-on. That is how we work.
GDPR by design
Data minimisation, consent, EU hosting and a signed data processing agreement before any personal data is touched.
Documentation you can audit
Written specifications, architecture notes, test reports and handover documents, so your team or auditors can follow every decision.
Accessible by default
Interfaces built to WCAG guidelines, helping you meet the European Accessibility Act for digital products and services.
Predictable contracts
Fixed scope and price, clear milestones and acceptance criteria, and full ownership of the code and IP.
What our .NET modernization covers
.NET Framework to modern .NET
Projects and libraries moved to current .NET, with incompatible APIs replaced.
Web Forms and MVC to ASP.NET Core
Old web apps rebuilt on ASP.NET Core, or with a React front end where that serves users better.
WCF to modern APIs
WCF and SOAP services replaced with REST or gRPC APIs, keeping existing clients working during the move.
Cloud and containers
IIS and Windows Server hosting moved to Azure, AWS or containers on Linux.
Database modernization
SQL Server upgrades, Entity Framework updates and migration to managed cloud databases.
CI/CD and testing
Automated builds, tests and deployments so every release is safe and repeatable.
Remote, but close to Paris
Time-zone overlap
Central European and Indian working days overlap by three and a half to four and a half hours, so your team is online for stand-ups and calls every morning your time.
The GDPR and the French Data Protection Act (Loi Informatique et Libertés)
We design to the GDPR and CNIL guidance: data minimisation, consent, access controls, encryption, data hosted in France or the EU, and a data processing agreement signed before work starts.

AWS Europe (Paris), Google Cloud europe-west9 (Paris) and Azure France Central, in your own cloud account, so data stays where your rules require.
How it works
1. Free assessment
We review your code, dependencies, infrastructure and data, then give you a written migration plan, risks and a fixed quote.
2. Plan and safety net
We add automated tests and monitoring around what exists today, so every change can be checked against the old behaviour.
3. Migrate in small steps
Module by module, with both versions running side by side where needed. You see progress in a demo every week.
4. Cut over and support
A planned switch-over with a rollback path, then the same engineers stay on to fix, tune and keep it current.
