I developed a scalable video platform with React and TypeScript, improving load times by 40% for 10,000+ users. I implemented backend services with Nest.js and Node.js, handling 1 million requests daily with 99.99% uptime. Key achievements include reducing load times by 30%, securing the platform with OAuth 2.0 and JWT, and enhancing code quality and productivity through automated testing, CI/CD, and mentoring.

Revitalized an outdated legacy reservation system by architecting and deploying a modern version using ASP.NET, C#, Java, Spring Boot, Node.js, and Express.js, ensuring a seamless technology transition. Modernized the frontend with React, Svelte, Angular, and TypeScript, integrated with FluentUI for a cohesive design. Engineered reservation logic in Java, JavaScript, and Node.js to prevent double bookings and optimize asset management. Implemented advanced authentication with Azure and MSAL, leveraged Hadoop and Azure Data Lake for big data processing, and crafted CSS templates for consistent styling. Built a robust backend with AI support, adopted Docker and Kubernetes to streamline deployments, resolved race conditions with optimistic concurrency, and improved UX using FluentUI and Adobe XD. Automated workflows with PowerShell and Bash scripts, enhancing operational efficiency.

Implemented a responsive UI for PayPal’s transaction platform with React.js and Angular, improving load times by 30% and user satisfaction by 25%. Added a payment-splitting feature with React and Redux, increasing engagement by 10%. Led a website redesign for consistent cross-browser styling and enhanced user experience. Developed a reusable React component library, cutting development time by 30%. Conducted testing with Jest and Enzyme, reducing bugs by 40%. Collaborated on RESTful APIs for seamless data integration and ensured mobile-friendly, cross-browser compatibility.

I estimated engineering efforts, prioritized tasks, and resolved production issues to enhance team efficiency and project timelines. I developed scalable software for growing user bases, built web applications with HTML, CSS, and jQuery to improve user satisfaction, and engineered user experiences that boosted engagement and retention. Collaborating with cross-functional teams, I ensured seamless project delivery while also gaining skills in React, Object-Oriented Design, Data Structures, Algorithms, Databases, and Software Engineering, contributing to both personal growth and team versatility.
