Bespoke Web Applications

I build bespoke web applications – online software that runs in your web browser – for businesses and organisations in Colchester, across Essex and Suffolk and throughout the UK. With over 20 years’ experience of planning, specifying, building, testing and maintaining online applications, I can take your idea from a first conversation to a secure, reliable system that your team uses every day.

What is a web application?

A web application (or online application) takes the form of a website, with pages, links and forms, but does the job of a software application you might run on your PC. Well known examples are Gmail (managing email), eBay (auctions) and Amazon (retail). Simply speaking, a website’s main job is to give information to visitors, whereas a web application collects, processes and presents information (or data).

For example, a retailer might need a secure online system to store and process customer, supplier and order data, automatically produce formatted documents (e.g. quotes, purchase orders and invoices), send out order tracking emails and produce comprehensive reports.

What I build

Examples of my work

One of the largest projects I have worked on, for a well known national weight loss company, was to specify, build, test and maintain a comprehensive online application to run the entire multi-million pound business. Key features include storage of vital data for tens of thousands of clients, 24 hour, browser based access for hundreds of employees and optimised, real time reporting on large amounts of data. I have personally been solely responsible for the build and maintenance of this system since 2004.

Other examples include:

Why a web application?

Advantages over installed (offline) software include:

How I work

I also use AI to speed up development where it helps, which can make a project quicker and more affordable than you might expect: read how I built CV parsing into a client’s CRM in about a week.

Sectors

I have considerable experience in the following industries / sectors, for which I can provide examples and current references:

Questions

How much does a web application cost?

It depends on what the system needs to do. Many projects start with the essentials and add features over time, which spreads the cost and gets a working system to your team sooner. Call or email for a no-obligation chat and I’ll give you an idea of costs and timescales.

Can you replace our spreadsheets or Access database?

Yes, this is one of the most common web applications. See online databases for more.

Do you look after the system once it’s live?

Yes. I maintain and keep developing the applications I build, in some cases for many years, so your system can change as your business does.

Do you only work with businesses in Colchester?

No. I’m based in Colchester and work with many businesses across Essex and Suffolk, but my clients are all over the UK, from Oxford to Scotland.
