PROFESSIONAL EXPERIENCE

Confidential, Colorado Springs, CO

Sr. Software Engineer

Responsibilities:

• Involved in various phases of Software Development Life Cycle (SDLC) of the application.
• Developed applications Java8 and new features of java (lambda expressions).
• Design and developed the application using HTML5, CSS3, SASS, jQuery.
• Developed the responsive UI web pages using XHTML, jQuery, HTML, CSS, Java Script, JSF, Prime Faces, and BootStrap.
• Developed Application to asses JSON and XML from Restful web service from consumer side using Angular 8.
• Developed new libraries with MicroServices architecture using Rest APIs, Spring Boot and AWS.
• Transformed legacy application into a suite of cloud hosted MicroServices using Spring Boot and laid the groundwork for x10 traffic scale.
• Implemented JWT token for Authentication and Authorization of the application.
• Implemented Spring Eureka for service discovery, Spring boot Zuul proxy server for dynamic request routing, Netflix Ribbon for load balancing.
• Developed MicroServices with Spring Eureka to retrieve API routes for the entire cluster. Using this strategy each spring service in a cluster can be load balanced and exposed through one API gateway.
• Implemented Service Oriented Architecture (SOA) by developing and consuming RESTful web services.
• Used Object/Relational mapping tool Hibernate and JPA to achieve object to database table persistency.
• Involved in writing Thread safe blocks for Multithreading access to make valid transactions.
• Apache Mesos and Kubernetes were used as the best ecosystem to deploy and manage Micro-services.
• Worked on creation of custom Docker container images, tagging, pushing images, integration of Spring boot.
• Created the Docker containers and Docker consoles for managing the application life cycle.
• Used Maven as build and dependency management tool for creating WAR and JAR file to be deployed in application servers and integrated with Jenkins and Jenkins Jobs.
• Resolved bugs/defects in application by coordinated with team members of the project using JIRA.
• Used GitLab for version control management.
• Smoke Test and Acceptance Testing is performed with Selenium in multiple Java platforms.
• Developed test cases and performed unit testing using Junit.
• Experience in Updating, Modifying queries in Oracle 11g.
• Developed Stored Procedures, Functions, Packages and SQL Scripts using PL/SQL.

Environment: Java 8, Spring Boot, Angular 8, HTML5, CSS3, JSON, JavaScript, Oracle 11g, JPA, Junit 4.4, Mockito, GitLab, Docker, RESTful web services, Selenium, Apache Tomcat, Maven, Swagger.

Software Developer

Responsibilities:

• Involved in various phases of Software Development Life Cycle (SDLC) of the application.
• Involved in design of Class Diagrams, Sequence Diagrams and Event Diagrams as part of Documentation.
• Designed and developed the application to be responsive for desktop, mobile and tablets using Twitter Bootstrap (HTML5, CSS3, and JavaScript).
• Implemented J2EE design patterns like Singleton, Factory, Data Access Object (DAO)andService Locator.
• Implemented fail safe and circuit breaker patterns in Spring Boot Micro Service applications using Hystrix and monitored the services using Hystrix Dashboard.
• Used Spring Security for Authentication and Authorization of the application.

• Implemented MicroServices governance layer (Eureka and Zuul). Zuul proxy Server is to handle all the requests and does the dynamic routing of MicroServices.
• Used Spring Core Annotations for Dependency Injection and Spring Boot for MicroServices.
• Designed and developed the REST based Micro services using the Spring Boot.
• Developed several REST web services that produces JSON to perform tasks, leveraged by both web and mobile applications.
• Created computing and data resources on AWS using EC2and deployed Docker images. Managed and supported AWS Security related issues, such as IAM and S3 policies for user access.
• Utilized AWS Cloud Watch to monitor resources such as CPU memory, RDS DB services, ELB, EBS volumes; to set alarms for automated actions; and to monitor logs for a better understanding and operation of the system.
• Implemented REST based web services using JAX-RS annotations and consumed using HTTP services.
• Automatic documentation of APIs and web testing portal implemented with Annotations and Swagger UI.
