Yevhenii Zozulia

Software Engineer



Software engineering is my professional occupation since the beginning of 2011. Most of the time, I'm focusing on Apple's mobile platform and developing native applications for iPhones, iPads, Apple Watch, etc. However, I have experience with developing software for Android OS. As well, I'm designing and implementing server and serverless backend solutions for mobile apps.

I'm also paying attention to other stages of software development and product evolution in addition to technical capabilities. Starting from the business analysis of the idea, problem, or a new feature. Through the planning and project managing. Implementing all required changes to a system. Testing and verifying the final results. To the final product available for the users. I have experience with all these steps same as with leading and managing small teams.

Focusing on problem-solving and details related to it with described experience and skills allows me to find the optimal solution and make it real.
