Hi there! Vadim here, a highly motivated Mobile App Developer with a strong passion for developing robust, scalable applications. I enjoy working with Dart and Flutter to design clean, maintainable solutions. My path wasn't traditional; I'm a self-taught developer. I have been relied upon to address complex challenges, optimize workflows, and manage smooth integration of automated testing. My approach is always very detailed, ensuring that each project meets high standards and exceeds expectations.
I am also passionate about sharing my knowledge in Dart and Flutter. I aim to help developers at different stages of their learning journey. I prioritize improving performance and delivering truly amazing user experiences, which are essential in the competitive field of app development.

Since October 2023, I have led a team of four mobile developers (including myself). My responsibilities included planning, establishing workflows and automations, mentoring, architectural design, and decomposing new features.
I optimized the design review and iteration process by integrating own implementation of Widgetbook (eliminating the need to wait for builds to appear on TestFlight; instead, we can simply share a link) and by splitting the app into universal modules, such as UI Kit.
