What I'm looking for

I'm looking to build high-quality mobile products where I can work closely with product, backend, and design teams, deliver polished iOS and Android experiences, and contribute from prototype through production.

I've built production mobile applications and SDKs for CreditChek, including a mobile SDK that helps third-party apps integrate CreditChek services with minimal setup.

Across CreditChek, EV1, Soft-web LTD, and Uneleap, I've developed and maintained Flutter applications with clean architecture, responsive interfaces, Firebase integrations, APIs, and polished user experiences. I've delivered apps for iOS and Android while collaborating closely with product, backend, and design teams.

I've also built a Student Management Dashboard in Next.js and a Hospital EMR system in React, working with RESTful APIs, global state management, Docker, and scalable frontend workflows.
