Vishwanath Patil Email and Phone Number

- Focussed on creating platform-based backend systems leveraging the AWS platform to support a variety of existing and new product models representing a wide variety of Pearson's consumer base. (Java, REST - Microservices, AWS - (ECS, DynamoDB, CloudFormation, CloudWatch, S3, IAM, Route53, VPC - [Subnets, SGs, ALBs]) )

1) Focussed on backend feature design and development on Nike's communication platform tool that helps extend exclusive member offers, rewards, and promotions. (Java microservices, SpringBoot, DynamoDB, JUnit, Mockito)

1) Led inter and intra team system design contract negotiations. 2) Led solution design efforts on the team for new and existing features.3) Led effort to migrate existing Java APIs from legacy RestExpress to SpringBoot framework.

1) Architected and implemented a composite service layer to existing service suite responsible for triggering real-time notifications to be broadcasted to recipients upwards of 50-100K. (RestExpress, Java, Aurora MySQL, MongoDB, Apache STORM, RabbitMQ)2) Designed and implemented features (user-blocking / unblocking, delivery via text & mobile-push, read-receipts on email deliveries) to extend Java based Notifications system. (AWS - (CloudWatch, SES, SNS), Apache STORM, MongoDB, RabbitMQ)3) Evaluated, devised and implemented a plan towards right-sizing API infrastructure thereby achieving an annual cost reduction of 55%. (AWS)4) Upgraded and fine-tuned backend system (Apache STORM) to derive increased efficiency resulting in higher throughput (from 16 emails/second to 100 emails/second) for delivering real-time notifications. (Java)

1) Built REST APIs in Java and Node.js and helped maintain database clusters and debug issues on both MongoDB and Cassandra across development, staging and production environments with 0 downtime on the APIs.2) Worked with Apache STORM (a distributed realtime computation system) which is used to manage a system built off of a suite of Java APIs that are responsible for triggering real-time notifications. 3) Built a custom full-stack product dashboard depicting product consumption statistics; currently being utilized by all of our consumer teams. (Dashing.io, Node.js and Mongo)4) Built and maintained multiple features on core Notifications service suite (responsible for triggering real-time notifications) along with backend engine maintenance with 0 downtime in Production for over a year. (RestExpress, Java, MongoDB, Apache STORM, RabbitMQ)5) Helped onboard new consumer teams and automated API request failure notice feature thereby cutting down support effort spent by approximately 75-80%.6) Worked on REST API developed with Titan Graph database as the backend.

1) Designed testing framework and developed tests for REST services on internal Java based automation framework.2) Created automation build jobs for integration tests for feature-based backend services using Jenkins.3) Written functional tests to aid developers with achieving maximum code coverage.4) Developed test cases in Selenium framework for UI automation in Java.5) Worked on various tools such as Fiddler, JMeter, Maven, Git, TestNG, Jenkins.

1) Worked in support and development for various modules: MM , SD , FI , PP.2) Development done using Agile software development methodology.3) Made use of ABAP/4 and OpenSQL for development. 4) Developed traditional reports, ALV reports, Smartforms, SAP Scripts and transaction codes.5) Worked briefly on ABAP Workflows and developed a test mail system for the organization.
