.NET expertise for complex,
business-critical software.
Build, modernise and secure the software your business depends on.
LughSoftware combines engineering in India with senior coordination in France to solve demanding software problems: complex business rules, legacy migrations, distributed systems and application security.
Discuss your technical challengeEngineering for the hard parts.
Some applications demand a deep understanding of the business behind the code. We design and develop .NET software for complex workflows, interdependent systems and demanding operational requirements.
- Translate business rules into a clear application architecture.
- Connect applications through APIs and well-defined data flows.
- Bring development, testing and delivery together within an agreed scope.
Our focus is software that can be understood, maintained and evolved as your business changes.


Move beyond the monolith.
Keep the business knowledge.
Migrating monolithic applications to .NET is a core area of our expertise. We understand the challenge of changing the technology while preserving the rules, data and workflows that users rely on.
- Assess the existing application and its dependencies.
- Define the target architecture and a practical migration sequence.
- Validate business behaviour and prepare the transition.
We also maintain and evolve existing applications, including during the move to .NET. The migration plan defines coexistence, testing and release responsibilities around your operational needs.
Designed to operate
across regions.
Our experience includes systems deployed across three regions, with clustered databases and distributed caches. We connect architecture decisions to availability, data consistency and the realities of operating a business application.
Regional deployment, data replication and service continuity are considered together, with operational and support responsibilities defined as part of the engagement.

Experience building applications that operate across multiple regions.
Database clusters and distributed caching within a coordinated architecture.
Availability commitments available within a defined contractual scope.
The SLA specifies the services covered, measurement period, maintenance windows, exclusions and associated operating and support arrangements.

Security within
the application.
We have built multi-factor authentication systems and application access controls. This experience informs how we approach identity, permissions and sensitive operations within business software.
- Design authentication flows around the application and its users.
- Define permissions for features, actions and data.
- Integrate security requirements into development and testing.
The security scope is agreed around your application, existing identity environment and operating responsibilities.
A clear path through complexity.
Understand the system
Examine the product, business rules, dependencies and constraints before defining the work.
Design & deliver
Agree the architecture, deliverables and responsibilities. For turnkey engagements, we manage design, development, testing and delivery.
Validate & evolve
You validate the agreed milestones. We prepare the release and handover, with maintenance or operational support defined for the next stage.
