Why it works so well

You’ll feel we’re instantly part of your team.

Complete control and full transparency so you know exactly who’s doing what, when, why and at what cost. If inspiration hits and you want to add a new feature, we can react quickly without additional contracts and authorised change requests. It should feel effortless.

Your DECODE team works only for you

We completely immerse ourselves in your world, laser-focused on your goals. From the moment we start working together, we’re never distracted by other clients. It’s all about you.

We always have time to talk. And listen.

Working with top-tier clients over the years, we learned exactly what’s needed to establish and maintain clear communication. Keeping all stakeholders in the loop through frequent calls allows us to spot and fix small problems before they turn big. 

Focused on security

Avoiding security issues upfront can save development time and ensures a better product. Don’t just rely on external security scans – choose a team that takes it seriously.

Pixel-perfect design implementation

Our front-end engineers are obsessive about matching final approved designs to the pixel. We always work mobile-first for both web and apps, making sure performance is a top priority.

Focus on testing

The most successful teams are those who truly understand the importance of quality assurance (QA), so ours are tightly integrated with the QA team, collaborating daily.

Automate (almost) everything.

The best way to remove human error is to remove the human, so with a continuous integration and continuous deployment (CI/CD) approach, we don’t do anything manually if automation can do it better. We definitely keep communication human though.

Quality that enterprise-level software demands

We understand the complex requirements of the world’s largest brands, and we’re trusted by leading enterprises to deliver to the highest standards.

DECODE has built a reputation within Metaswitch as supplying quality code at the exacting standards we expect of our own developers.

Still unsure about something?

Don’t worry, whatever it is, we’ve got you covered in our FAQ.

This video demonstrates exactly that:

Other examples include:

  • When Apple removed Fling’s app from the App Store, we jumped on a plane to London the very next day to work 72 hours, non-stop. As our CEO said at the time: “I couldn’t be prouder of the team for making Fling even better than before, especially under such pressure.”
  • We flew to Dusseldorf to present an app to the Vodafone tech team in person.
  • We’ve prioritized CVs for a new addition to a client’s in-house iOS team. DECODE’s engineers sorted through them, analyzed the code and suggested the best candidates for the interview.

As for our team, we have weekly dev Scrums, daily stand-ups, all the people are together in one office, and we actively use Slack, Skype, Google Hangouts, GitHub, Bitbucket and more…

We like to automate everything to reduce human error whenever possible. Being able to implement sustainable continuous integration workflow is very important so we can deliver new versions regularly and often, ensuring there’s no regression and everything works as intended. 

We have written multiple articles about this topic available to read here:

We are used to working with big brands such as Metaswitch (a Microsoft company), Royal Caribbean, AT&T and Asseco SEE, so we understand what high-quality and carrier grade deliverables mean.

We even developed our own software product ( that helps big companies in their mobile development process.

This varies based on many elements including app platforms (iOS, Android or both), app complexity, feature list, business logic, developer team location, native app vs. cross-platform app development, cloud infrastructure, etc.

The cost of an app depends upon the number of features or customizations needed, timelines for app development and experience of the team or company you are hiring. It is always a good idea to ask companies for a ballpark quote so that you can compare the different options you have regarding cost and quality.

A basic mobile app for 1 platform could cost between $30,000 – $50,000

A medium-complexity mobile app for 1 platform, $50,000 – $150,000

A complex mobile app for 1 platform could cost more than $150,000

Based on our experience in the last 10 years, we’ve found out that working in dedicated teams gives the best result. That means one team working solely on your project. Creating a profitable and production-ready software product requires more than just coding. It needs a team to be fully involved, and able to change direction along the way based on market feedback.

Yes. In today’s environment, being agile is one of the most important things. Being agile doesn’t mean a lack of processes, but rather the opposite. Having good efficient processes and a strong working methodology helps us to be agile and at the same time organized and predictable.
