Senior🎓
Top SchoolSergio S is a seasoned full-stack web developer with 8 years of experience building complex web platforms, admin panels and analytics tools across Yii2, Laravel and modern JavaScript stacks like React and Vue.js. He has delivered production systems for classifieds, iGaming and eCommerce—designing REST APIs, background processing with queues/Redis, real-time chat via WebSocket, and mobile apps with React Native. Comfortable owning backend architecture and frontend integrations, he also crafts Composer packages and optimizes database queries for high-throughput services. Based in Kharkiv, Ukraine, he follows SOLID and TDD practices and brings practical ops skills from server and SSL/DNS setup to third-party API and payment integrations. An understated strength is his mix of product-focused engineering and hands-on tooling (including Python parsers), which helps turn ambiguous requirements into maintainable, testable systems.
