Led a comprehensive overhaul of core APIs serving over one million customers, transitioning from legacy XML-based APIs to modern OpenAPI specifications. This initiative was pivotal in enhancing mission-critical banking functionalities, including account opening, deposits, and account closure. The transformation utilized advanced microservices architecture and RESTful design principles, incorporating Kubernetes for container orchestration and service discovery to optimize performance and scalability. Implemented API gateways and load balancing to ensure high availability and reliability.

Adopted OAuth 2.0 for secure authentication and authorization, integrated with distributed tracing tools like Jaeger for monitoring and debugging, and utilized rate limiting and caching strategies to enhance throughput and reduce latency. Achieved a 50% improvement in API response times through rigorous performance tuning and asynchronous processing and reduced system downtime by 30% with fault-tolerant design and automated failover mechanisms. The project also involved extensive unit and integration testing, leveraging CI/CD pipelines to streamline deployment processes and ensure continuous delivery of high-quality code.

A digital enhancement project for CVS CarePass, integrating COVID-19 test booking and result viewing into the CVS Pharmacy app.

I utilized React Native for cross-platform mobile development and Expo for rapid development and deployment. Implemented Node.js with Express.js for scalable back-end services and used AWS Lambda for serverless computing and AWS S3 for secure file storage. Employed GraphQL for flexible and efficient data querying, Redis for in-memory caching to reduce latency, and MongoDB for schema-less data management. Integrated RESTful APIs for seamless data exchange and WebSocket for real-time notifications. Leveraged Docker for containerization, Kubernetes for orchestration, and Jenkins for continuous integration and deployment (CI/CD). Incorporated Firebase for user authentication and Elasticsearch for powerful search capabilities. This initiative streamlined the testing process, enhanced user experience with seamless appointment scheduling and real-time result tracking, and improved overall accessibility and operational efficiency.

Worked on continuously enhancing the FedEx mobile app, used by millions globally, offering a range of capabilities to enhance user experience and streamline package management. Users can track shipments in real-time, with updates on package location and estimated delivery times. The app allows users to create, schedule, and manage shipments, including generating shipping labels, requesting pickups, and managing delivery options.

Push notifications provide timely updates on delivery status, estimated delivery windows, and proof of delivery. The FedEx Delivery Manager feature lets users customize delivery preferences, such as holding packages at a FedEx location, redirecting to another address, or requesting vacation holds. The app’s document scanning feature lets users scan and upload essential shipping documents from their mobile devices.

The app offers quick shipping rate quotes, locator services to find nearby FedEx locations, and in-app customer support via FAQs, live chat, or direct calls to FedEx. Secure mobile payment options allow users to pay for shipping services using their preferred method.
