• Spearheading development of a Java microservice acting as a backend-for-frontend gateway designed to aggregate responses from backend services and streamline data for Grubhub restaurant menu pages, resulting in:- Unified backend responses, eliminating discrepancies due to varied requests and parameters, enhancing the reliability and accuracy of restaurant menu pages.- Achieved substantial reduction in payload sizes from backend services, with content payloads minimized to more efficient sizes, improving load times and system performance.- Developed strategies for resilient data handling during backend downtimes, ensuring functional data delivery to maintain uninterrupted user experience.- Introduced lazy loading capabilities, ensuring large payloads do not compromise the user's loading experience.• Implementing backend changes to enhance Grubhub’s menu item data modal, resulting in improved UI capabilities as well as providing more accurate menu-item cross-sell recommendations to users per item added to cart.• Tech Stack: Java, Scala, Apache Cassandra, Redis, AWS (EC2, S3, SNS, SQS, Elasticache), Guice, Docker, Mockito/Hamcrest, Gradle, Eureka, Postman, Jenkins, Datadog, Splunk, Gatling and Spinnaker.

• Developing Java backend microservices responsible for delivering Grubhub restaurant menu pages across various clients, with primary responsibilities including:- Returning available restaurant and menu data based on the location, time, and type of order for clients.- Utilizing AWS Elasticache clusters running Redis to cache restaurant data, ensuring reduced load onCassandra, enhanced API response times, and lower latencies/higher throughput for public-facing APIs.- Ingesting and processing messages from AWS SQS, initiated by upstream catalog services, to trigger updates for restaurant data in Cassandra utilizing up-to-date S3 data models.- Leveraging AWS SNS to publish updates to alternate datacenters and invalidate cached restaurant data, ensuring consistent and up-to-date merchant information across all regions.• Tech Stack: Java, Scala, Apache Cassandra, Redis, AWS (EC2, S3, SNS, SQS, Elasticache), Guice, Docker, Mockito/Hamcrest, Gradle, Eureka, Postman, Jenkins, Datadog, Splunk, Gatling and Spinnaker.

• Continued development of the Equinix technician portal using React, Node.js, and MySQL, adding features such as user authentication, error handling, and UI improvements resulting in a better user experience.• Created a full-stack web application using React, Node.js, and MongoDB allowing the Equinix Metal team to efficiently calculate latencies between various data centers at a 25% faster rate.• Maintained communication with the team on project progress made using workspace tools such as Confluence.

• Developed a full-stack web application using React, Node.js, and MongoDB allowing employees to report feedback of newly established interfaces, resulting in a 10% faster evaluation rate.• Built a GUI tool in Java to automate the creation of Excel sheets, reducing generation time by 15%.• Constructed a responsive web-based dashboard utilizing JavaScript and Bootstrap to visualize business KPIs.
