We modernise complex
business-critical systems
IT-Soft Ltd is a UK-based SME software team specialising in rescuing legacy platforms, modernising .NET and SQL Server estates, and building robust APIs and automation that actually match how your business works.
We act as a compact, senior engineering team—architecting, implementing, and documenting changes so your systems are easier to run, extend, and hand over.
What our team delivers
A small, senior-heavy team combining architecture, implementation, and documentation. We specialise in taking messy, business-critical systems and turning them into something you can trust and evolve.
Legacy system rescue & refactoring
We stabilise and modernise existing platforms without stopping the business. Incremental, low-risk change with clear rollback and documentation.
- Refactoring large .NET and C# codebases
- Untangling business logic from UI and data layers
- Improving performance and reliability of SQL Server
- Introducing modular, testable architecture
API design, integration & data workflows
We design and implement APIs that reflect real business workflows—clean contracts, clear documentation, and predictable behaviour.
- REST API design and implementation in .NET
- Integration between CRM, billing, and line-of-business systems
- Data migration and synchronisation strategies
- Postman-ready contracts and examples as standard
DevOps, automation & delivery pipelines
We bring structure to how your software is built, tested, and deployed—reducing risk and manual effort.
- Azure DevOps pipelines for build, test, and release
- Environment strategy and configuration management
- Automated deployment of services and databases
- Operational runbooks and handover documentation
Modernisation without disruption
Many of our clients can’t afford a “big bang” rewrite. We work alongside your existing teams and systems, improving what you have while designing where you’re going.
- Audit of current architecture, pain points, and operational constraints
- Prioritised roadmap: stabilise first, then extend and improve
- Incremental refactors that reduce risk and increase clarity
- Clear communication with both technical and non-technical stakeholders
How our SME team works
We operate as a compact, multi-disciplinary squad—architecture, backend, database, and delivery—so you don’t have to coordinate a dozen suppliers.
- Senior engineers who can both design and implement
- Atomic, well-documented changes that are easy to review
- Regular demos and progress checkpoints
- Focus on maintainability, not just “getting it working”
Technology stack & domains
We’re comfortable stepping into complex, regulated, and long-lived environments—especially where the system has grown organically over years.
Core technologies
We also work comfortably with legacy patterns and older frameworks, designing a path to more modern, modular architectures without forcing unnecessary rewrites.
Typical sectors & systems
Our experience spans multiple industries, but the common thread is always the same: complex workflows, high stakes, and systems that can’t just be turned off.
- Energy and utilities platforms
- Property and asset management systems
- Telecoms and network management tools
- Enterprise CRM and internal line-of-business apps
