Sergey Melnikov

I am a seasoned Full-Stack Software Engineer with 10+ years of experience building scalable and user-friendly applications. Proficient in JavaScript, TypeScript, Node.js, React, and React Native, with a deep understanding of UI/UX best practices. Experienced in startup environments, consistently delivering critical features and full projects from scratch with speed, reliability, and high code quality. Known for my proactive approach, I take ownership of complex features and lead initiatives independently. I’m also passionate about mentoring, having supported and guided junior developers to grow in their roles. I care deeply about crafting seamless user experiences and optimizing performance.

Currently, I work as a developer and team lead in Smart POS Inc. I am responsible for the development and maintenance of three key projects: a web e-commerce platform (using React, Node.js, GraphQL), a B2C e-commerce mobile app (React Native, for IOS), and a POS system (React Native, for Android). Each of these products plays a crucial role in the business, and I ensure they are scalable, high-performing, and deliver a seamless user experience.
