Software Consultancy
Modernising Software.
Optimising Performance.
Delivering Practical Solutions.
Sheldon Software helps businesses identify and solve the technical problems holding their websites and applications back.
From independent technical audits and performance optimisation to legacy modernisation and software development, we focus on practical improvements that make your software faster, more reliable and easier to maintain.
About Us
Sheldon Software is an independent software consultancy specialising in modernising web applications, improving software performance and helping businesses get more from their existing technology.
Software that has been in use for years can become increasingly difficult to maintain, slower to develop and more expensive to support. Websites can suffer from poor performance, technical SEO issues or usability problems that affect both users and the business.
We help businesses understand these problems and identify practical ways to address them. Rather than recommending unnecessary rewrites or adopting technology for its own sake, we focus on the improvements that provide genuine value.
Whether you need an independent technical assessment, improvements to an existing website or application, or support developing new functionality, we can help you understand what needs to change and deliver the right solution.
What We Do
We help businesses identify problems with their websites and software, understand what needs to change and implement practical improvements.
Audit
Understand what's really happening. We assess your website or application across performance, technical SEO, accessibility, usability and maintainability to identify the issues that matter.
Optimise
Improve the things that are holding your website or application back, from Core Web Vitals and page performance to accessibility, usability and technical SEO.
Modernise
Reduce technical debt and bring ageing software up to date through refactoring, framework upgrades and improvements to architecture and maintainability.
Develop
Build new features and web applications where development is the right solution, using modern technologies and engineering practices designed for long-term maintainability.
Why Sheldon Software?
We believe good software consultancy starts with understanding the problem, not choosing the technology.
Independent Advice
Recommendations are based on your business needs and the condition of your existing software, rather than a preference for a particular platform, product or technology.
Practical Solutions
Not every problem requires a complete rebuild. We look for proportionate solutions that address the underlying issues while making sensible use of the systems and investment you already have.
Long-Term Thinking
Improvements should make software easier to maintain and evolve. We consider the long-term impact of technical decisions rather than focusing solely on solving the immediate problem.
