Abrar Ul haq

I'm a software engineer with three years of experience building scalable web and mobile applications using React Native, Next.js, Firebase, and Node.js. I focus on clean code, data-driven decisions, and user-centric solutions.

At my current role I led the development of serverless applications that improved API response times by 40% and reduced overall page load times by 25% through query optimization and caching. I collaborated with product and design teams and used A/B testing and analytics to prioritize features that increased user engagement by 15%.

My project work spans mobile and web: I built HIPAA-aligned features and encrypted data flows for a women's health app, implemented native device APIs and geolocation for a social app, and helped migrate a legacy platform to Next.js and MongoDB to improve performance and maintainability. I also implemented retry logic in Firebase Cloud Functions that reduced data-loss events by 90%.

I thrive in agile, cross-functional teams where I can own end-to-end features, optimize performance, and deliver polished user experiences. I enjoy mentoring through code reviews, refining UI components for reuse, and continuously improving delivery with CI/CD and testing practices.
