About ME

Mobile app developer for Android and iOS. I can develop new applications from scratch, maintain or add new features to existing ones. In parallel with the development of mobile applications, I often have to work on CI/CD flows. I like to use new technologies when and where it is possible.

Product Quality

Product development uses the best possible tools. I focus on clean code and the maintainability and scalability of the final product. I always happy to advise you on the best technical solutions.

Project lifecycle

During the planning stage, I gather and analyze your requirements so I can prepare a quality solution on time and within budget. I then carry out thorough research to define the technology stack and the product concept of a future app, and to prepare a product specification, wireframes, and other project documents.

Based on the wireframes I got after the planning stage, I start preparing a product prototype that you actually can click on. I then design the UI of your future app. The UI of your app can be also complemented with strong branding, if necessary.

Since design and development are closely dependent on each other, these are usually performed simultaneously to speed up development. Development is accomplished in sprints, each lasting for two weeks. Working in sprints allows me to gradually demonstrate the results of development to you.

I also perform iterative testing to generate working software early in the software lifecycle. I fix any bugs in the system before its actual release, which allows for delivering the most pleasant and smooth user experience for your customers.

I also provide post-release support services available for a period determined by you. Supporting and maintaining a product after launch makes it possible for you to constantly improve your product’s quality to meet the needs of end users. I can make any improvements to your product quickly without impacting its performance.
