PROFESSIONAL EXPERIENCE

Client: CSX, Jacksonville Dec 2019 to Current

Role: Senior Software Developer

Project: The Joint Wayside Diagnostic System (JWDS) is designed to track and monitor rail equipment health. JWDS does this through a network of over 1,000 defect detectors connected to CSX’s back-office systems. Once information is received, the data is processed against pattern matching algorithms compared to previous detections from multiple detectors. This allows CSX to look at information over time and perform predictive diagnostics before rail incidents occur.

Responsibilities:

strategic rewriting of these backend systems into modern Spring Boot APIs

Create new services source data from MongoDB collections and are layered with well-designed experience

Create APIs that aggregate data from both Oracle and MongoDB. This hybrid approach played a critical role in managing phased cutover scenarios,

Implemented Azure processor to upload and download files to Azure.

Created API’S using spring REST to fetch data from oracle procedures.

operates in a technical lead capacity, particularly when coordinating complex production change implementations.

Develop deep understanding of enterprise systems, particularly in the space of legacy web

application support and backend transformation.

Maintaining and evolving applications built on Prime Faces, while simultaneously leading efforts to decouple the backend from monolithic Oracle stored procedures.

Implemented processor to upload detector raw files to AWS S3 bucket.

Deployed processor spring boot apps on AWS EC2 instances.

Used AWS SQS and SNS client in camel app to read and process files.

Created reusable Angular UI components and integrate them with backend APIs.

Used maven for application build and configuration.

Used Oracle 18C database to process the data and mapped it to Spring JPA

Used Eclipse/IntelliJ IDE’S for developing applications and deployed to OpenShift and WAS9

Used Jenkins for the build and deployed the application.

Modified Oracle procedures for modernized applications

Environment: Java 17, Spring boot 3, Spring REST, Spring boot Mongo dB, spring JPA, Spring IOC, Oracle 18c, slf4j, Maven, Jenkins, OpenShift cloud, Apache Kafka, AWS, Angular 5.

Client: WellsFargo, Charlotte May 2016 to October 2019

Used Spring Batch to process large volumes of data for transactions.

Hosted web applications and REST APIs using Spring Boot with embedded Tomcat.

Developed Rest Client module to consume REST URLs using Spring REST Template.

Involved in developing integration modules for the application. Some of the modules include core components, ingestion-services, client-services, common-services.

Developed and consumed Rest Services using HTTP methods such as GET, POST, PUT and DELETE.

Used Gradle for application build and configuration.

Used Oracle 12C database to process the data and mapped it to Hibernate Configuration File and established data integrity among all tables.

Used Eclipse IDE for developing applications and deployed to Tomcat Application Server.

Used Jenkins for the build and deployed the application to IBM Udeploy.

Developed SQL queries for updating and accessing data from database.

Environment: Core Java/J2EE, JDK 1.8, JSP, Hibernate 5.4, Spring MVC 5.2, Spring IOC, Oracle 12c, Multi-threading, Junit, Gradle, Log4j, JDBC, Jenkins, Udeploy, Jfrog, Linux.
