Boston, Massachusetts, United States

I engaged in all phases of SDLC, from requirements gathering to deployment and maintenance, using Scrum methodology in an agile environment. I developed Spring Cloud functions-based Lambda functions and native microservices with Spring Cloud libraries, integrating AWS with other application infrastructures. I implemented AWS solutions using EC2, S3, EBS, Elastic Load Balancer, Auto Scaling groups, and CloudFormation Templates. I developed APIs with AWS Lambda, created user interfaces with HTML, CSS, JavaScript, Angular 11, JSON, and AJAX, and enhanced web page performance. I refactored microservices architecture, developed high-performance back-end applications with Node.js, implemented API Gateway, and ensured secure authentication and authorization with OAuth 2.0 and Spring Security. I deployed CI/CD pipelines with Jenkins, Git, Docker, and AWS, using TestNG and Mockito for testing and JIRA for tracking.

Dallas, Texas, United States

I was involved in designing web pages using HTML5, CSS3, JavaScript, Bootstrap, Angular 10, and MongoDB. I collaborated with front-end developers and designed back-end services for business processes. Utilizing Java 8 stream APIs for bulk operations on collections, I oversaw the migration of existing applications into microservices architecture using REST APIs, Spring Boot, and AWS. I deployed and maintained AWS EC2 instances in Docker and developed Spring Boot-based microservices, implementing Spring Cloud/Netflix API architecture patterns. I designed a mock UI WebApp in Angular 10 to demonstrate microservices and integrated client-side code with RESTful services, ensuring seamless functionality and efficient web design.

Austin, Texas, United States

I worked extensively on server-side templating languages, front-end technologies, and Node.js frameworks. I implemented a Single Page Application (SPA) with Angular 8, designing the front-end insurance management interface using HTML5, JavaScript, and jQuery. I developed a web application based on microservices using Spring Boot and Spring Cloud for load-balancing and monitoring. I created reusable TypeScript components and secure authentication services using JSON Web Token and SAML. Utilizing Spring Security and Hibernate, I managed database access and developed a cloud-hosted application with embedded Tomcat. I integrated Jenkins and Docker for CI/CD pipelines in AWS, and employed TestNG for unit testing, ensuring robust application development.

Chicago, Illinois, United States

I worked on complete Agile development, including story grooming, estimations, retrospectives, and sprint planning. I utilized Modernizer extensively to build cross-browser compatible HTML5/CSS3 layouts and developed user interfaces with HTML5, CSS3, JSON, AJAX, Angular 4, and TypeScript. I used Angular 4's routing, services, views, directives, and HTTP Module for API calls. I developed Spring Boot applications to streamline configurations and implemented microservices for a service-oriented architecture. Working with AWS services, I utilized EC2, S3, VPC, EBS, Elastic Load Balancer, RDS, and Auto Scaling groups. I integrated Spring ORM frameworks with Hibernate for database operations and used Jenkins for continuous integration, employing TestNG for unit testing and Git for version control.

Bengaluru, Karnataka, India

I utilized Agile Methodology (SDLC) to manage projects, leveraging Java 8 features like Lambda Expressions, Functional Interfaces, Stream APIs, Time API, and enhancements in Collections, Concurrency, and IO. I developed and implemented Swing, Spring, and J2EE-based MVC frameworks and designed a session module for an existing ColdFusion application. Using Struts and Spring MVC, I built front-end applications and middle-tier services. I created web pages with HTML5, jQuery, AJAX, and JavaScript, and implemented Spring IoC and AOP for service layers. I developed DAO and persistence layers with Hibernate and JDBC, and wrote SQL queries and stored procedures. I used Apache Ant for deployment, GitHub for version control, and JIRA for bug tracking, ensuring thorough unit testing with JUnit.
