ASP.NET developer

Need an ASP.NET developer for an app someone else built?

Your developer has moved on, and now something needs changing or fixing. A senior .NET developer looks at how your site or app is built, quotes a fixed price, and makes the change without breaking what already works.

How it works

  1. 1

    Tell us what you need

    The address of the site or app, and the change or problem in your own words.

  2. 2

    Get a fixed price

    We look at how it's built and quote the change before any work starts.

  3. 3

    Safe change, then release

    Made and tested on a copy first, released when you're happy, with a note of what changed.

Typical jobs

  • Fix an error that appeared after a server or Windows update
  • Add a field, a page or a report to an existing system
  • Change how a form, a price or an email works
  • Connect it to a new payment provider, CRM or Microsoft 365
  • Move it off an old Windows server onto supported hosting
  • Find out what's there, where the code is, and what it would take to update

Why it's not a risk to call us

Someone else built it

That's normal. The first job is reading how it was built, and we write down what we find so you're never stuck again.

Old versions are fine

WebForms, MVC, Web API and WCF on .NET Framework, SQL Server and IIS, as well as modern .NET up to .NET 10.

No surprises

A fixed price for the change before work starts, and nothing released to your live site until you've seen it.

Site down or broken right now? Tell us what's happening. For ongoing cover, see legacy app support.

Questions

Do you take on small jobs?
Yes. A single fix or change is a normal way to start. We quote it as a fixed price once we've seen the code.
What do you need from us to quote?
The site or app's address, a description of the change, and if you have them, access to the code or the server. If you don't know where the code is, tell us and we'll help work it out.
Our site is very old. Can you still work on it?
Usually, yes. We work on ASP.NET WebForms and MVC on .NET Framework as well as modern .NET. If something is too risky to change as it is, we'll say so and explain the options.
Can you look after it after the change?
Yes. A Care plan from £450 a month + VAT covers monitoring, security updates and small changes, with one engineer who knows your app.
Are you a freelancer or an agency?
Tech Pixels Ltd is a UK limited company led by a senior software architect with 14 years on .NET. You deal with the engineer doing the work.
