Our services

Many of our clients want us to handle the whole project, while others only need certain aspects. Here’s the full run-down of our services:

We’ve been on the front line for many newborn startups, armed only with an idea and endless enthusiasm. We’ve seen some brilliant decisions – and some not-so-great choices – and all that experience has taught us that strategy and research is vital.

Through workshops and modern research methods we’ll test your idea, make sure it fits the market and show you how to turn it into reality. We’ll lay the foundation before writing a single line of code.

Through our 4-stage process we’ll make sure all bases are covered.

Summary and key findings presentation

We offer an entire suite of end-to-end design services. Our approach involves utilizing in-depth research, data, and valuable insights to develop and implement user-centered experiences that are simple and effortless to navigate.

  • UX/UI design
  • Design systems
  • Prototyping

If you already have a visual identity, we can make sure everything we produce follows your brand guidelines.

This is what we absolutely love to do. It’s what DECODE was founded on, and we still live and breathe it today. Messaging apps, social platforms, mobile banking – we have the experience to take on any challenge.

If you’re a startup, what you’ll need most is an agile team that can iterate quickly, producing new versions every week so you can see tangible progress.

If you’re an established company, you want products that are testable, scalable and reliable, with excellent documentation and comprehensive testing code coverage. No regression, no unproductive back and forth, everything delivered on time.

Quality assurance

Many brag about senior developers but forget to mention quality assurance. That’s where they try to save money. We don’t.

What truly sets us apart are our QA engineers and processes. Enterprise-grade software requires quality assurance at the highest level.

Here’s why our QA works so well:

  • Code reviews
  • Code guidelines
  • Test automation
  • UI tests
  • Code quality tools
  • Unit tests

Our passion for quality assurance also led us to build our own crash and bug reporting tool →
