BLUE CHIP GROUP LLC, DALLAS TX June 2014 - June 2016

FULL STACK DEVELOPER

Project Description: Built Unified System Portal (USP) a security application using Angular, Node.js, Amazon Web Services (AWS), Single Sign-On Authentication, Docker and Kubernetes, GitLab and Helm for deployment, NPM, ES6.

●As a front-end developer, I developed a web portal using Angular, TypeScript, RxJS, NgRx Stores, and Effects. I followed ES6+ standards and utilized NPM to manage dependencies. I also created several services using dependency injection to communicate with backend services via the HTTP Client module.

●Utilizing RxJS Observables, Subject and Behaviour Subjects, Redux, NgRx Store and Effects, I developed multiple components that update data near real-time on the user interface (UI). I also created shared resources like services, pipes, custom directives, and components that are reusable in various components throughout the application, adhering to standards and best practices.

●Following test-driven development methodologies, I developed each component, module, service, and directive of the Angular application using Jasmine, Karma, Istanbul, and Headless Chrome. I ensured that each newly built function was properly tested and that the unit test coverage met and frequently exceeded expectations.

●I developed REST APIs that were consumable internally and externally with Node.js, Express, and Serverless frameworks using Amazon Lambda Functions, DynamoDB, Athena, S3 Bucket, and other AWS services. I also created models and interfaces that defined the data for both requests and responses and tested requests, responses, classes, and models in APIs using Mocha and Chai with Sinon and Supertest.

●To test the entire application end-to-end, I utilized the Robot Framework and ExtendedSelenium2Library specifically for testing Angular. I also documented REST APIs using Swagger specifications.

●For easy deployment across multiple environments, including Local, CI, INT, and PROD, I created several Docker files for building images for services. I created YAML files and bash and shell scripting to create multiple services inside responsive (scale up and down) Kubernetes pods. Additionally, I debugged and managed microservices in Kubernetes clusters, and provisioned Kubernetes clusters using Python Azure SDK.

●As a team player, I participated in pair programming with new developers and actively participated in all Agile Scrum meetings (Daily Standups, Sprint Retrospection, Sprint Planning, and Code Review) where I provided updates and coordinated meetings.

FIS GLOBAL LLC, DALLAS TX Jun 2012 - Jun 2014

JAVA DEVELOPER

●As a full-stack developer, I implemented REST API endpoints using a variety of technologies, including Java, Multithreading, Collections, Generics, Exception Handling, Servlets, Custom Tag Libraries, Struts, Spring, Microservices, Hibernate, Enterprise Java Beans, and JDBC. I designed and implemented Spring Security for the application, enabling authentication against LDAP, J2EE pre-authentication, and the database.

●Working on the entire Model View Controller (MVC) architecture of Struts, I handled the Request Processor, Action class, Action Form, and Validation Framework. I ensured that the application was thoroughly tested by writing extensive JUnit test cases using test-driven development before implementing any new functionality or fixing any old functionality.

●On the front-end side, I implemented the Angular boilerplate, modularizing and structuring the files such that every major feature has a module and corresponding sub-modules. Additionally, I added shared modules for common custom pipes, directives, and components. I configured the Angular routing module, ensuring that lazy-loading was achieved for optimized performance of the application. I also managed the states of the Angular application using RxJS, Observables, NgRx stores, and effects.

●To ensure the quality of the Angular application, I performed test-driven development and wrote hundreds of unit tests for Angular components, directives, pipes, reducers, actions, services, and effects using Jasmine, Karma, Istanbul, and Headless Chrome. I documented the Angular application using the Compodoc module and optimized Angular components for maximum performance across a vast array of web-capable devices.

●To track defects, issues, and risks, I used Jira, ClearQuest, and Quality Center. Additionally, I applied strong analytical, interpersonal, and communication skills, demonstrating a track record of analyzing situations and implementing solutions in a fast-paced environment.
