About DXD

DXD exists to solve challenging software problems.

We work with local governments, infrastructure, highways channel-partners and commercial companies to implement strategies that connect remote hardware to the internet to increase operational efficiencies.

DXD was formed to provide software for a series of infrastructure projects in the UK. Initially, DXD partnered with a number of companies that supplied variable message signs, vehicle counting and road safety technology.

Subsequently, DXD's business grew to monitor and support multiple intelligent transport systems, Smart City and road safety initiatives for a range of clients. Our software consultants gained experience working on projects for airports, NHS hospital trusts and prominent leisure developments.

Today, DXD focuses on API design, cloud solutions and web interfaces centred on the Internet of Things (IoT) revolution.

We help clients to create strategies, technology and platforms to monitor assets, improve efficiencies and enhance revenues. No matter what remote equipment you want to connect, from custom API integration to data connectivity to hardware automation and web interfaces, DXD has you covered.

DHF Products provides integrated ecommerce and fulfilment services, focused on B2B markets.

Ecommerce fulfilment requires speed and efficiency. B2B customers expect fast and reliable delivery of the products they purchase online, and business managers need access to comprehensive, real-time data. 

DHF has the technology and expertise to improve every aspect of your ecommerce order fulfilment process.  We manage E-Fulfilment so you can focus on growing.
