At Devsar we follow an agile approach. We split the development work into small sprints of work of about 2 or 3 weeks. The starting point is the product backlog, a set of top-level and prioritized tasks that we use to get an overall idea of the product. On the kickoff (and subsequent) sprint meetings, we analyze and define these top-level task with the client and then select a handful that can be developed in 2 weeks. Once a week we do a standup call with the client to make adjustments on the workload if needed. We believe this method reduces the chances of falling and commit errors and allows customers to change the requirements and adapt the app at any time without affecting the product roadmap. This well-proven methodology is quite flexible and give clients a truly ownership of the project while our team gets a real understanding of the scope of the product.

These guys develop the actual application. They’re solution-oriented people, who analyze users’ needs, design, develop & test the software that meet those needs. They're in charge of the entire development process, ensuring that the system continues to function normally through their life-cycle.


These are exceptionally creative people, for whom UX, wireframing or responsive issues are no nuisance. They spend most of their time creating and drawing beautiful assets, icons and designs, which will be later used to create visual concepts. They're visual-thinking problem solvers.


Team Lead/Tech Lead — This person is usually the most senior developer in the team, he’s responsible for answering and resolving any technical problems the team or the client may have, choosing the best stack based on the technical challenges and proposing the underlying architecture.


This is the person who takes care of the product backlog and is in constant contact with the client, ensuring we’re building the right thing. Product Managers can answer any questions the team may have about features to be built, bugs to be addressed, priorities etc.
