Senior Java Developer

{ Bank of America Jan 2022 – Present}

The Aim of the project is to design and develop APIs that processed streaming data to power customer recommendation engines which resulted in incremental annual revenue and also developed Java bean components to implement business logic that streamlined an internal application and also led the routing of control from web services to Java services using the Spring Boot / Spring IO and Hibernate ORM which reduces the development cost.

Worked on user interface guidelines and standards throughout the development and maintenance of the website using the HTML5, CSS3, JavaScript and JQuery.

Designed and implemented multiple APIs using Spring Boot Restful/Microservices framework and Java 8 features.

Implemented microservices using Spring Boot, Spring Cloud, Spring Microservices, and enabled discovery. Used Microservices with Spring Boot predicted service interacting through amalgamation of REST and MQ message broke.

Utilized Java 8 features like Lambda expressions and Stream API for Bulk data operations on Collections which would increase the performance of the Application.

Involved in Enhancement of existing application utilizing Angular, created HTML navigation menu that is role based wherein menu items changes dynamically based on the values derived from the database in the form of JSON.

Used Angular JS as framework to create a Single Page Application (SPA) which can bind data to specific views and synchronize data with server.

Worked on Restful web services which enforced a stateless client server and support JSON few changes from SOAP to RESTFUL Technology Involved in detailed analysis based on the requirement documents.

Implemented MYSQL database on simple queries and writing stored procedure for normalization & deployed the project into Jenkins using GIT version control systems.

Work with the database Developers, software developers and Development lead, to architect and implement new features and solution for customers.

Designed and implemented a Cassandra NoSQL based database and associated RESTful web service that persists high-volume user profile data.

Developed AWS Lambda to create new back-end services for your applications that are triggered on-demand using the Lambda API or custom API endpoints built using Amazon API Gateway.

Championed in Software Configuration Management (SCM) in Agile, scrum, and Waterfall methodologies.

Java Developer

{HSBC Jun 2019 – Dec 2021}

Worked in processes and figure out the optimal architecture for the application. After initial analysis solution architects found that there was an immediate need to re-architect the application and re-build it on containerized architecture. A DevOps team was orchestrated to automate the entire application delivery process. The continuous integration/continuous deployment was automated using Jenkins. The containerizations were delivered through Amazon Elastic Kubernetes Services and developed a centralized log forwarding system from the application.

Worked on REST API calls and integration with UI. Used AngularJS to develop the component to the application team, Spring MVC to consume REST API's and used JavaScript, CSS3 and jQuery to display the data in front end.

Used Microservices with Spring Boot predicted service interacting through amalgamation of REST and MQ message broke and Used Eclipse as IDE for development.

Implemented Docker containers to create images of the applications and dynamically provision slaves to Jenkins CI/CD pipelines

Worked on Spring Boot with microservices and MVC model to create an ecommerce application along with restful API.

Used AWS Lambda to create new back-end services for your applications that are triggered on-demand using the Lambda API or custom API endpoints built using Amazon API Gateway.

Working on AWS Elastic load balancing for deploying applications in high availability and developed API for using AWS Lambda to manage the servers and run the code in the AWS.

Designed and implemented a Cassandra NoSQL based database and associated RESTful web service that persists high-volume user profile data.

Agile methodology is being followed where there are daily SCRUM meetings to understand the status and resolve any issues under hard deadlines.
