Web APP development
We build complex projects from the ground up, with a proven track record of delivering successful web-based software products, alongside entire web infrastructures for mobile applications.
What we do
Front-end
React
We favor React for front-end development. It’s very fast for developing, has great performance and offers a wide range of reusable components.
Angular
Angular is an excellent choice for complex, large-scale applications. Its robust, opinionated structure and powerful tools support scalable, maintainable growth as your application expands.
Vue
A progressive JavaScript framework ideal for building user interfaces and single-page applications. Its flexible architecture and gentle learning curve enable developers to create responsive, high-performance apps while easily integrating with other libraries.
Back-end
Python
A solid backend foundation is crucial for your application’s success. We use Flask or Django in Python. Flask is a lightweight, flexible framework, ideal for smaller applications and APIs. Django, on the other hand, is a comprehensive “batteries-included” framework with built-in ORM, admin panel, and authentication—perfect for rapid development and scalable applications.
NodeJS
Node.js is a modern, high-performance platform for scalable backend systems. Express.js is the minimalist standard framework, offering maximum flexibility. For larger applications, we use NestJS, which provides a modular architecture and TypeScript support. Node.js integrates seamlessly with React or React Native, enabling a unified JavaScript or TypeScript codebase.
Ruby on Rails
This proven framework enables developers to build database-driven applications quickly and efficiently. With its “convention over configuration” approach, Ruby on Rails accelerates development and is particularly well-suited for startups, MVPs, and full-stack web applications.
Java
Java is a reliable and versatile programming language used for high-performance backend systems, enterprise software, and cloud applications. In addition to Spring Boot and Quarkus, we also leverage native Java solutions to build efficient and scalable architectures.
Java Spring and Quarkus
Java remains a top choice for enterprise applications. Spring Boot provides a stable, scalable, and secure environment for long-term, complex solutions. Quarkus, on the other hand, is specifically optimized for cloud-native microservices, offering ultra-fast startup times and low memory consumption—perfect for Kubernetes environments.
Why it works so well
A reliable and scalable team
We deliver what we promise. The team can scale when needed so you can get to market
quickly, while ensuring your product meets customer demand.
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.
Front-end and back-end specialists
It’s important for these two teams to be distinct so they can choose the right tools for their specialism and develop tailored best practice. Always collaborating with continuous communication.
Continuous Integration & Deployment
We store our code on Bitbucket and use their pipelines to trigger our code quality checks and run tests.
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.
Cloud-connected
We aim to run all our infrastructure in the cloud, maximizing automation by taking advantage of Amazon Web Services and Heroku.
Infrastructure as code
We use Terraform so we can quickly and predictably create new environments and change existing ones, making projects more robust, reducing human error.
Our Work
We’ve loved working with many fantastic companies, and are really proud of what we’ve achieved together.
DECODE has built a reputation within Metaswitch as supplying quality code at the exacting standards we expect of our own developers.
Our collaboration models
Project-based
We complete software products regardless of scale.
End-to-end projects
Proof of concept
Pilot projects
Here’s how we differ from other agencies
- Project managers with extensive tech knowledge.
- Our team focuses exclusively on your project. No context switching.
- We are product-minded. We look at all angles of your product, not just the coding part.
Extreme transparency
Regardless of the collaboration model, you’ll have complete communication access to every team member working on your project. You’ll also know exactly who’s doing what, when, why, and at what cost.
The secret to success — open communication
It’s more than just talking—it’s about building processes, guiding meetings, and fostering a big-picture culture.
Surround yourself with individuals who understand the ‘why’ behind their actions, driving your projects to meaningful success.

NEXT STEPS
Before we start our partnership, we have to make sure
we’re a right fit for you.
Over a relaxed call or two, we’d like to hear as much as possible about your project
(fully NDA’d of course).
We’ll talk about:
- Your expectations
- Services you need
- Your vision
There are a few steps in this phase:
- We’ll hand-pick a team based on your desired seniority level and other requirements.
- We’ll send you their CVs so you’ll know every engineer working for you.
- If necessary, we can set up interviews between you and every engineer.
Only when you’re 100% on board with our choice, we’ll go to the next phase.
If everything sounds good to you, we’re ready to get started.
This could be the start of a great partnership
Want to get in touch? Just fill in the short form below, or skip to the bottom to arrange a chat direct with our Head of Partnerships. Either way, we’ll be back in touch as soon as we can to arrange an informal call.
Don’t worry, any information you give us will only be stored for business purposes. Find out more in our Privacy Policy.

Software team lead explains coding standards and guidelines
Working on enterprise-level projects is quite different from working on smaller projects. Codebase size, coding standards, documentation and many other factors all have to be taken more seriously, as enterprise-level projects have high standards.
