How we work
We follow Agile software development methodology and build trust-based partnerships with all of our clients.
Discuss
What is your app's main value? What are your business objectives? Any third-party solution you'd like to integrate with? We need to have a clear picture of what you have in mind. As a result of this stage, we will provideyou with a bare scope and cost estimations.
Strategize
Strategizing includes drawing a mind map, writing use cases, designing user flows, defining technology stacks, preparing test documentation, and more. You'll get a precise scope and cost estimations and a product development roadmap at the end of this stage.
Iterate
We organize our process in two ways: Scrum or Kanban. Kanban is greatfor projects that require flexibility. Scrum works best for projects with a precise scope. We follow a continuous delivery approach with dailymeetings and demos at the end of each iteration.
Improve
After we launch your product, we can help you maintain and support it.Our support activities include 24/7 critical bug fixing, stability monitoring, internal engineering team coaching, protection from security vulnerabilities, and planning new releases.
