About

Hi, I’m Zeeshan, a passionate and results-driven Frontend Engineer with over 5 years of experience building performant, user-focused web applications. I specialize in crafting responsive, accessible, and intuitive interfaces that balance great design with clean, scalable code. I’ve contributed to diverse products across startups and enterprise environments, including impactful work at TeamViewer, where I developed AI-powered features and real-time data visualizations for smart glasses. My tech stack includes ReactJS, Angular, Next.js, TypeScript, Redux, Tailwind CSS, Material UI, Styled Components, and Storybook, along with tools like Docker, Git, Figma, and Jira. Beyond frameworks and libraries, I value thoughtful UX, robust architecture, and agile collaboration. Whether it’s building a design system from scratch or integrating RESTful APIs, I bring a hands-on, detail-oriented mindset to every project. I’m always exploring new technologies, refining my skills, and looking for opportunities to create meaningful digital experiences. Let’s connect if you’re working on something exciting or just want to talk frontend!
