Developing Software in Java using Spring Boot

Roseland, New Jersey, Us

Developed major parts of tax notice and amendment processing real-time system, using Java, Spring, JSON, Kafka, and REST.Implemented new system to provide real-time updates to clients, reducing turnaround time from 1 day to 5 minutes, and avoiding clients seeing incorrect data.Increased logging throughput and reduced overall size to avoid data issues in production servers, resulting in 40% less logging-related issues.Spearheaded and setup continuous integration system, reducing errors and deployment time by at least 30%.Raised code quality via automated tests and checks for coding guidelines, resulting in a faster feedback loop and 30% less deployment issues.Drove adoption of agile development processes, especially Scrum.Created application to fix over 200,000 database entries in a day, which would have taken weeks to do manually.Provided solid code via Test Driven Development, refactoring, and automation of menial tasks.

Led development of an in-house product for managing flood insurance determinations and customers for banks and insurances, utilizing Java, JSP, XML, Hibernate, ASP .Net, C#, SOAP, and Oracle.Improved the overall development process by introducing agile principles from Scrum and XP: Iterative development, daily progress reports, time boxed development, frequent update of end users, lean approach to requirements and implementation, continuous integration, daily builds, and automated testing.Just-good-enough requirements gathering and iterative deployment of key features saved at least 3-6 months extra development effort.Pushed for frequent releases, which allowed changes to the final product when missing features were discovered during the usage of the real application, instead of solely relying on requirements and prototypes. Because of this the end user satisfaction improved by over 50%.Simplified and streamlined the process for developer builds, integration builds, and deployments, resulting in a ten times more efficient process, and reduced the error rate during deployment by at least 25%.Coordinated distributed development between teams in the USA and India.

Led teams of three to five developers in the timely delivery of a JMX based monitoring application for Motorola and Pfizer, doing hands-on development in Java, as well as high level and detailed design.Promoted and established process steps for an easily maintainable code base.Initiated usage of a Wiki for internal communication, documentation, process management, and brainstorming.Enhanced daily builds by automatically enforcing coding and design guidelines, as well as capturing violation of component encapsulation, further reducing problems during deployment.Setup continuous integration of the software, which reduced manual labor of keeping code deployable by 90%.Unified the usage of regression tests and unit tests, providing tips and guidelines along the way.Improved the build process by streamlining the scripts, resulting in overall improvement of 25%.

Designed and developed cross-platform software (for PC and Mac) for the printing industry using TDD and cont. integration practices
