.NET and C# development for business systems that have to be reliable

We build and maintain ASP.NET, .NET Core and Blazor applications: payment and remittance platforms, trading engines, portals and back offices, often hosted on Azure (see Azure development). Our in-house team builds and supports .NET applications, and you own the code we write for you.

What we build with .NET

Examples from our own projects, described in general terms.

Payments and remittance

Angular portals and .NET services on Azure for a global remittance platform. See the Xpress Money case study.

Trading and financial engines

A .NET trading engine and API that runs options strategies within per-underlyer risk limits. See the Rainbow Capital case study.

Ordering and back offices

Blazor quote calculators, checkout flows and back offices, and storefronts with distributor portals. See the Top Tier Editing case study.

Portals and CRMs

Long-running ASP.NET websites with agent CRMs, live chat and reporting for support organisations.

Legacy .NET modernisation

Upgrades from .NET Framework to current .NET, and ageing middleware replaced with Azure services.

Hosting and delivery

Azure App Service with deployment slots, and builds through GitHub Actions or Azure DevOps.

When .NET is the right choice

.NET suits systems that handle money, records or compliance and have to keep running for years:

  • Payment, trading and finance platforms with strict rules and audit needs.
  • Companies already on Microsoft 365 and Azure.
  • Long-lived products where a typed language and mature tooling pay off.

For a marketing site, WordPress is cheaper to run; for a quick product with a JavaScript team, Node.js. We will say which we would choose and why.

What clients say

Jatinder has been a valuable team player and leader for us as we worked to develop our revolutionary technology. Recently, we integrated our software into Oracle's technology and our code went through and passed the Oracle review process for certification which is in large part due to Jatinder's talent, attention to detail and professionalism.

The highest recommendation for our software developers is to rehire them for future projects and Jatinder has earned this recognition more than any software developer on our team. We look forward to continuing to work with Jatinder in the future and delighted to be able to leave this positive feedback for him today as it has been so well deserved.

Manpreet has been instrumental in revamping our business. We needed to update the whole flow of our customer checkout and their experience on the portal where they manage their orders. Manpreet really delivered. I couldn't be more pleased with his work. He is timely, efficient, very communicative, and always meets deadlines. He helped to us to understand the technical work we required in language we could understand. Most of all, he is very personable and willing to meet regularly to update you on his work and provide and guidance and input. He went well above what was expected. I would like to hire him for another project on a different website. Thank you, Manpreet!

Manjinder has been great to work with on our project. He has been with us for over 3,000 hours of work and is one of the best programmers we have worked with on a project (we have worked with over 50 developers.) I highly recommend Manjinder from both a professional and personal level. He possesses superb ASP.net and SQL skills plus great communications skills making him the ideal candidate for any small, medium or large-scale development project.

Ashu is a very experienced programmer, with first class communication skills and knowledge of a wide range of coding technologies. He worked with a new team environment well, performing individual tasks as prescribed. We look forward to working with him again in the future.

Manpreet was the best partner for this complex and demanding job! He fulfilled it on time even though he has to learn new technologies that he has no previous experience. I have already the next project for him ready. Excellent work! Highly recommended!

Sarbjit did a great job moving our public blog from BlogEngine.NET to Wordpress. This migration contained a lot of complexities, users, comments and database structure that had to be moved and Sarbjit handled it masterfully. Thanks Sarbjit!

Technologies we use

What our .NET projects are built with. Linked technologies open our page for them.

Frequently asked questions

Do you develop in C#?

Yes. C# is the main language for .NET development, and we use it for ASP.NET web applications, WPF desktop applications, back-end services and Xamarin mobile apps.

Which .NET technologies do you work with?

ASP.NET web applications, WPF desktop applications, universal applications, integrations and Xamarin mobile development.

Can you work on a legacy .NET application?

Yes. We maintain and modernise older .NET applications, starting with a review of the code.

Who owns the code?

You do. You can check the code repository at any time to see the quality of the work.

Do you sign an NDA, and who owns the code?

We sign an NDA before work starts, and you own the code we write for you.

How do I get a quote?

Use the form on this page or book a project call. Tell us what you need and we come back with questions and next steps.

How can we work together?

There are three ways, on the same terms:

  • Dedicated team, best for ongoing work: interview the developers, then they work on your project full or part time.
  • Fixed scope, best when requirements are clear: we agree the scope and the price up front, and deliver against it.
  • Time and material, best when the scope will change: you pay for the time used and can change priorities as the work goes on.

Whichever you choose, we sign an NDA before work starts, you own the code we write, and every change is reviewed in your repository.

Can I interview the developers before we start?

Yes. For a dedicated team you meet the developers in an online call and interview them before they join your project.

Have a .NET project in mind?

Tell us what you need built, fixed or modernised. We come back with questions, a suggested approach and an estimate.
