Viktor Sinkovskyi

Hi, I’m Viktor, and I work as a React Native Developer at the OSKI Solutions. We develop mobile applications and digital platforms that help communities worldwide access educational content, religious resources, community services, and organizational programs.

 At OSKI Solutions, I help build and maintain cross-platform mobile applications for iOS and Android, delivering reliable and scalable solutions that serve thousands of users. My work focuses on creating high-quality user experiences, improving application performance, and ensuring long-term maintainability through modern engineering practices.

 With over 6 years of experience in software development, I have developed expertise in mobile application development, software architecture, and technical leadership. My primary technologies include React Native, TypeScript, JavaScript, Expo, React, Node.js, GraphQL, TRPC, AWS, REST APIs, and modern CI/CD workflows. I also have extensive experience designing reusable libraries, optimizing application performance, and leading mobile development initiatives.

 Throughout my career, I have combined hands-on engineering with technical leadership responsibilities. This includes mentoring developers, leading small teams, making architectural decisions, and collaborating closely with product owners and stakeholders to deliver business value.

 My key strength is the ability to bridge technical excellence with business needs. When working on projects, I focus on: 

• deeply understanding product requirements and user needs

• designing scalable and maintainable architectures

• making clear and pragmatic technical decisions

• ensuring predictable and transparent delivery

• maintaining high standards for code quality and performance

Over the years, I have worked on a variety of products, including community platforms, educational applications, content-driven mobile experiences, and shared mobile frameworks. My primary goal is always to improve usability, performance, scalability, and long-term maintainability while creating measurable value for users and organizations.

 Outside of work, I enjoy exploring mobile technologies, software architecture, developer tooling, and emerging trends in the React Native ecosystem. I believe that great software is built through strong collaboration, continuous learning, and a commitment to delivering meaningful impact. Every project is an opportunity to innovate, grow, and create solutions that make a difference.
