I’m a React Front-End Developer with 4 years of hands-on experience crafting production-ready, responsive applications. I specialize in performance optimization, building scalable high-performance UI, and keeping architecture clean so users get seamless experiences across devices.

In my work, I focus on measurable speed and usability wins—implementing code-splitting and lazy loading in React to reduce initial load time by 50%. I’ve also optimized web performance to improve page load speed by 60%, and I translate Figma designs into pixel-perfect, responsive UIs to raise user satisfaction scores by 22%.

At Starthub (03/2024 - 01/2026, Pakistan Remote), I developed 30 reusable, production-ready UI components, accelerating feature delivery and reducing development cycles by 30%. Collaborating with designers and back-end developers in Agile sprints, I cut development time by 44% and helped deliver 10 features on time while working across multiple concurrent projects.

Earlier, at Speakable (02/2023 - 06/2024, Pakistan Remote), I implemented robust frontend-focused features for industry tools, managed complex states using Redux Toolkit, and increased website SEO performance by 35%. At uConnect Technologies (2022 - 2023, Gilgit, Pakistan), I built and styled responsive UI components with React.js and Tailwind CSS, integrated RESTful APIs via Axios and Fetch (improving data load time by 40%), and used testing practices from Cypress/Testing Library alongside Git-based code reviews.
