Work Experience
Windstream
Software Engineer
Jan 2022 - Feb 2024, Little Rock, Arkansas
Reduced Windstream’s quoting application tool (PAO) workload by 12% by creating RESTful APIs using Swagger, Hibernate, and Java, communicating with Windstream’s customized Salesforce (WinForce) API to update customer information and view the JSON quotes submitted to WinForce.
Led PAO migration into a microservice architecture, which helped streamline workflow and improve collaboration across teams. Created RESTful APIs that enable teams to save quotes to the PAO database, load JSON quotes, provide real-time product availability, and submit quotes to WinForce.
Improved PAO’s address accuracy by 30% by building a Java Address Validation tool that interacts with the USPS API for address validation and cross-references with multiple responses from Google API. Leveraged the response to display geo-coordinates and network elements from an internal Geocoordinate API.
Enabled user access to the Address Validation tool through a RESTful API and implemented spreadsheet upload and download functionality, including a template spreadsheet. This feature allows users to submit bulk requests using the template and receive corresponding bulk responses efficiently.
Achieved a 15% decrease in quote revision resubmissions to the sales manager by creating a newly designed PAO summary page, which displays all product changes across all locations since the last submitted quote, and modified the PAO final report to reflect revisions from the summary page using Java, HTML, and CSS.
Formulated new features for product availability and pricing based on quote locations and business requirements including PAO’s pricing database integration for accuracy.
