Hi, I'm Abu Sayed — a Frontend Developer with 4+ years of experience building modern, scalable, and user-friendly web applications. I specialize in React, Next.js, and JavaScript, with strong skills in building responsive interfaces and delivering seamless user experiences.
Over the past few years, I have worked as a Front-End Developer at Spekter GmbH, where I built and optimized complex UI components, integrated advanced features, and ensured cross-device responsiveness using React, Next.js, and Tailwind CSS. I've worked on scalable web applications with focus on performance and user experience, including implementing intricate UI components and interactive map functionalities.
While I'm primarily focused on frontend development, I'm actively expanding my backend knowledge and working with Node.js, Express, and MongoDB. I'm building full-stack projects to strengthen my backend skills and become a more well-rounded developer. I'm currently preparing for Frontend Software Engineer (Level 2) positions, with expertise in modern frontend stacks (React, Next.js, React Native, TypeScript, REST APIs, and testing frameworks).
