Keep Your Systems Running
Keep your critical .NET systems running, stable, and secure, with a team that understands legacy inside out.
Modernise with Confidence
Take existing .NET systems forward: Framework migrations, API transformations, and cloud transitions, done incrementally, safely, without disrupting your business.
Legacy .NET Modernisation
Phased migration from .NET Framework 1.1–4.8 to .NET 8/10, preserving business logic, module by module.
Learn more02VB6, Access & Classic ASP Migration
Pre-.NET estates nobody left can maintain, migrated incrementally to modern .NET with the existing system running throughout.
Learn more03API Development & Integration
REST APIs, gRPC services, and third-party integrations built with contracts-first design and proper documentation.
Learn more04Legacy Apps to Cloud Migrations
Move your on-premise .NET systems to Azure or AWS, with zero-downtime deployment and cost optimisation.
Learn more05Modernisation Assessment
A fixed-scope, fixed-price engagement that maps what your legacy .NET system actually contains and what moving it forward would really take.
Learn moreHow Working Together Is Actually Shaped
The services above are what can be done. This is how an engagement is structured and paid for — four steps, in order of commitment, each stating what it deliberately does not cover.
Technical Diagnostic
For you if: You suspect the estate is a problem but nobody has established whether it actually is, or whether now is the moment to spend money on it.
- A 45-minute call — with me, not a salesperson — about what the system does and what is prompting the question.
- A short written summary afterwards: which .NET version you are on, whether it is still in support, and where that leaves you.
- The two or three biggest risks as they stand, named specifically rather than as general warnings.
- A straight answer on whether modernisation is worth doing yet. Sometimes it is not, and that is a useful thing to know for free.
What this is not: This diagnoses. It does not plan. A migration plan requires reading your code, which is the paid assessment below — anyone offering you a costed plan off the back of one call is guessing, and the guess will be wrong in your favour until the invoice arrives.
Book the free diagnosticModernisation Assessment
For you if: You have accepted something needs doing and now need a number you can take to a budget holder — one that will survive contact with the code.
- A system and dependency map: what the application is actually composed of, and which versions you are pinned to.
- A named risk register rather than general warnings, including anything already out of support.
- A per-module position on incremental migration versus rebuild, because the answer is rarely the same across a whole estate.
- A phased plan with effort sized per phase and the assumptions shown, so your engineers can challenge them.
- A costed first phase — or a written explanation of why the system should be left alone, which is a legitimate and reasonably common outcome.
What this is not: The fee is credited in full against the modernisation project if you proceed within 90 days.
Request the assessmentFixed-Scope Modernisation Project
For you if: The assessment is done, the phases are agreed, and you want the first one delivered against a scope and a price that were both worked out by reading your code rather than estimated from a description.
- A fixed price for the agreed phase, produced by the assessment rather than quoted off a conversation.
- The phases delivered section by section, with your existing system running throughout.
- Architecture and code review by me on every phase — that part does not get delegated.
- Tests written alongside the work rather than promised for later, and a build that fails on warnings.
- A working, deployed system at the end of each phase, not just at the end of the project.
What this is not: There is no published price band here on purpose. Anyone quoting you a range before reading your code is guessing, and the guess runs in their favour until the invoice arrives. The assessment produces the number; once it is agreed it is fixed, and work beyond the written scope is quoted separately rather than absorbed silently.
See how we workSupport & Maintenance Retainer
For you if: The system is business-critical, the people who built it have gone, and you need someone who knows why it works the way it does to still be there in two years.
- Bug fixes, security patching, framework and dependency upgrades, and performance work on a system I already know.
- A named person — me — rather than a ticket queue and a rotating cast.
- Continuity of context. The reason clients stay is that we are the ones who remember why a particular calculation works the way it does.
What this is not: Not a lock-in: the minimum term is a single month, and it runs rolling after that. The figure depends on what the system is and what keeping it healthy actually takes, so it is set after reviewing it rather than published as a band. And a retainer is not an unlimited change budget — new capability is scoped and quoted as project work, while the retainer keeps what exists running and current.
