Sound Familiar?

It still works. But changing it feels like a risk.

Most of our work starts with one of these.

A .NET Framework application that can't move to modern .NET
WebForms or WCF with no clear upgrade path
The developer who built it retired, and the knowledge went with them
It runs the business, and everyone is afraid to change it
Security scans keep flagging it, and vendor support has ended
It works, but it's slow, brittle, and expensive to maintain

The first step is understanding what you have and what needs to change.

Where we can help

A way forward for the software you depend on.

Start with the problem in front of you. We can work out the right size of solution together.

Modernize

Move beyond a legacy platform.

Incremental migration to modern .NET. Work through WebForms and WCF dependencies, separate the parts that need to change, and plan releases around the business.

A starting point: map the dependencies and identify the first migration boundary.

Maintain

Make an existing system easier to live with.

Get to grips with unfamiliar code, investigate recurring faults, and make the day-to-day work more reliable. Ongoing support keeps the knowledge with the system.

A starting point: trace a recurring failure and make the fix repeatable and testable.

Connect & build

Give your team fewer manual steps.

Connect applications that do not talk to each other, automate repetitive work, or build a custom web application around the way your business actually operates.

A starting point: follow one workflow from the first entry to the final report.

How we work together

A clear next step. Then the next.

You should understand what is changing, why it matters, and what you will have when the work is done.

Understand
Talk through the system, the people using it, and the problem you need to solve.
Agree on the work
Define a useful first scope, the deliverables, and the price before development begins.
Build & verify
Make the change, test the behavior, and review the result with you.
Leave it understood
Document what changed, hand over the code, and agree on any ongoing support.

A few practical details

Flexible Pricing: Hourly or project-based with milestone payments. Scope and pricing are set after a no-cost initial assessment of your system.
You Own Everything: You own the code, always. Complete intellectual property rights transfer upon project completion.
Remote-First: Remote-first approach with in-person meetings available when needed.

Start a conversation

What does your system need to keep doing?

Tell us what you have, what is getting difficult, and what a useful next step would look like. You do not need a finished specification.

What happens next

We will review your message and follow up to understand the problem. Together, we will discuss how we can help and what an initial assessment should cover.
