Expert Software Development and Web Design

About

App Software Ltd is my software development company. I'm Gareth Brown, and I build software solutions, usually in the form of web applications, APIs, and cloud integrations. I live on the Somerset / Wiltshire border in the UK, working with clients nationally and internationally.

What I Do

I've been building software professionally for over 18 years, for companies of all sizes. Clients I have worked for include public sector organisations and FTSE 100 companies including UKSBS, Maersk, Dyson, and O2 (I will also very happily work with smaller companies too).

I've delivered many projects including end to end application build and deployment, re-development / modernisation of existing applications and extension of existing systems. I can work as a sole developer with skills covering the entire technical stack and software development life cycle, or join existing teams in either a lead or support capacity. I focus on creating robust, maintainable solutions that solve real business problems.

Your Project

How I Can Help

Whether you need someone to build a new application from scratch, modernise an existing system, or provide technical architecture guidance, I can help. I work as an independent contractor or can integrate into existing teams, in a lead or support capacity.

I focus on writing clean, maintainable code with security and performance in mind. I prefer proven patterns and well-established technologies wherever possible. My goal is always to deliver something that performs well and can be maintained long into the future.

My Approach

I work with modern frameworks and tooling while being pragmatic about technology choices. Not every project needs the latest framework or architectural pattern - sometimes simple is best. I'll recommend what makes sense for your specific needs and constraints.

My services include hands-on development, technical consultation, architecture reviews, and code audits. I'm happy to discuss what would work best for your situation.

What My Clients Say

"Gareth rapidly understood the ecosystem and helped us get back on track to smoothly extend and modernise the existing .NET based systems to enable a move into new global markets. At the same time he brought his expertise creating the foundation for the system to grow beyond the initially designed program."
