Lead Mobile / Full-Stack Software Engineer
About Me
I am a Lead Software Engineer with over 9 years of strong hands-on experience in mobile web and full-stack environments. My main specialization is React Native and TypeScript, although I am not limited to this setup. I am able to lead cross-functional teams, deliver and maintain high-traffic applications, design and implement CI/CD pipelines, and improve code quality through continuous testing and code review. I also have experience in cloud platforms such as AWS, Azure, and GCP, as well as DevOps, backend systems, and solution architecture.
Among the most valuable applications in my portfolio are the Screwfix Mobile application, which I developed over 4 years as a greenfield project, and the EpicGames Modes Store, developed over 1.5 years. Overall, I have completed 8 finished applications. I am passionate about technical leadership and mentoring, and I enjoy driving architectural transformations and improving team workflows.
Currently, I serve as a Mobile Tech Lead at Patrianna, where I drive the technical evolution of legacy mobile architecture and consult on mobile department structure adjustments. I am hands-on in this role and collaborate closely with C-level executives and stakeholders to align technical goals with business needs.
Previously, I worked as a Lead Software Engineer at EPAM, where I was responsible for architecture, design, and implementation of multiple large-scale mobile applications for iOS and Android. I actively participated in development, technical decision-making, and acted as an interim solution architect. I led migrations, developed complex native integrations, and authored comprehensive technical documentation.
I have also volunteered as a Backend Developer, gaining production-grade experience with Node.js, NestJS, Prisma, and PostgreSQL. I implemented security-critical features, designed database schemas, and integrated OAuth 2.0 / OpenID Connect and third-party services.
My educational background includes a Master of Science in Control Systems for Aircraft and Aerospace Systems from the National Aerospace University "Kharkiv Aviation Institute." I am certified as an AWS Certified Associate Solutions Architect and have completed the Solution Architect School at EPAM.
I am fluent in English at an upper-intermediate level and continuously seek opportunities to grow both technically and as a leader in software engineering.
