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



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 is another we’re very familiar with, and a particularly good choice if you’re aiming to build a Software as a Service (SaaS) product.



A robust back-end foundation, designed around your business goals, is vital. Our go-to framework is either Flask or Django in Python, with the former offering more flexibility, while the latter speeds up development so you can ship quicker.


Another option is NodeJS. Increasingly popular, with a great active community for open-source frameworks, and it plays nicely with ReactNative, meaning an entire codebase in javascript.

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.


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.

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.

CEO at DECODE, Marko Strizic


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
  • Engineering seniority level you require
  • Technologies you need
  • Your vision

If we both feel we’re a great fit for each other, we can move on to the next step.

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.

I am continually impressed by the level of pride and ownership that DECODE takes in the work they perform for us. They treat our products as if they are their own, which translates into better user experiences for our customers.
