About Erika

At my last client, I built an automation that increased advisor commissions from £2.5M to over £5M for a 12-person team, without adding headcount. I also reduced a critical CRM form load time from two minutes to one second.

I'm a freelance .NET developer and founder of Lokivia Software Solutions. I help companies modernise legacy applications, automate manual processes, and improve the performance of business-critical systems.

Many organisations rely on software that has evolved over years: WinForms applications, VB.NET codebases, spreadsheets, manual data entry, and processes held together by workarounds. Replacing everything isn't always realistic—or necessary.

That's where I come in.

I specialise in modernising legacy .NET applications, extending the life of existing systems, reducing technical debt, streamlining workflows, and helping businesses get more value from the software they already have.

I primarily work remotely while maintaining close communication with stakeholders, and I'm happy to work onsite when it adds value to the project.

If you're looking to modernise an existing .NET application, automate repetitive processes, improve performance, or migrate legacy systems, I'd be happy to discuss your project.
