As part of the Enterprise Integration Platform (EIP) team, supported the successful HR/P modernization effort to replace a 35-year-old mainframe system with a cloud-based Workday implementation. Contributed to development of three Spring Boot applications running on Azure servers that retrieve and parse XML-structured data files from Workday and supply text files and data streams to campus partners. • Designed and led two mission-critical integrations with the Department of Retirement Services (DRS) utilizing the EIP framework. Extended existing components to meet security and auditability requirements. Added client connectors to customized UW ServiceNow REST framework, UW Enterprise Document Management REST API and UW Identity Management REST API.• Aided in initial POC and later implementation of transition from MongoDB as a data backend to SQL Server. Re-wrote JavaScript data transformations into T-SQL views and stored procedures. Developed further data transformation scripts and data quality analysis scripts, with associated tSQLt unit tests.• Championed efficient automated testing. Researched and developed tools for mocking third-party services. Coached team members in automated testing best practices.

Contributed to Reflection ZFE product, an innovative, zero-footprint, HTML-5 based terminal emulator. Collaborated with geographically distributed team to develop this new Java-based server with JavaScript (RequireJS and JQuery) front-end.• Improved performance of touch-based and tabbed navigation on iPads.Enhanced the Reflection X Advantage product, a distributed multi-tier X server allowing collaborative, secure access to X hosts. The architecture of this Java application is event-based, with communication between components in RMI using TSL. • Migrated persistence layer from eXist database to XML flat-file to meet requirements for reliability and backup. Wrote extensive XSL transformations to upgrade existing databases. • Implemented SOCKS proxy support for SSH connections.• Added support for a new version of XInput protocol, including development of X clients written in Java for testing.Led initial code design for new Java product, FileXpress Gateway, allowing tunneled SFTP connections configured through a web interface. Worked with two external teams to leverage existing components, a first for the Attachmate development group. Web interface was written with GWT on top of an MVP middle tier with an LDAP back end. Configuration of SFTP connections was made via REST calls to the native Reflection for Secure IT product. • Introduced the team to Spring and Maven, developed the initial build framework. • Participated in security threat analysis of product as part of the Attachmate secure development lifecycle.• Analyzed and improved custom IO code to improve SFTP transfer times for large files by 25%.Supported legacy Reflection PKI Services Manager, fixing bugs, upgrading RSA Crypto-J library and Java versions and aiding FIPS recertification.

Lead Product Development scrum team through three major releases of the Digital Commerce Solutions product. Primary focus was on initial development, subsequent feature work and maintenance of a core user and organization management subsystem. System requirements include high reliability, security and scalability, using Spring, Hibernate, ehCache, Apache Tomcat and REST Webservices. • Developed initial architectural and quality standards for the subsystem including automated test suites. Enforced quality standards and maintained architectural integrity of the subsystem through subsequent releases as team composition changed.• Clarified requirements and project done criteria with the Product Owner, triaged defects and helped team members prioritize work.• Enhanced security, adding authorization to sensitive remote Java API calls and implementing credential policies around complexity, history and expiration.As part of the Solutions Delivery development team, participated in two releases enhancing the functionality of a distributed back-end system for a major mobile network operator. Efforts included leading a small team effort across two time zones to ingest major upgrade in e-commerce platform and transitioning application container from Tomcat to WeblogicExpress.

Worked to establish agile software development processes within IT group of the newly formed Institute of Translational Health Sciences (ITHS). Assisted scientists in evaluating software needs and initiated development of searchable database of resources available to ITHS researchers.

Developed software tools enabling retrieval and visualization of terabytes of seismic data to the international research community. Documented technologies and agile development techniques for software group and wrote white papers explaining relevant technologies to board members.• Lead small team effort to expose seismic data using SOA techniques, unifying data access mechanisms with streamlined servers. Technologies included Spring, Hibernate, JiBX and Axis2. Designed web service access to data via both SOAP and RESTful methods, including integration with mapping tools.• Created AJAX web application and Axis SOAP server to access back-end Oracle database, with data display of resulting XML through XSLT. • Worked with a small, distributed team to create a Java-based portlet application enabling community access to seismic models running on a computational grid. Mentored junior developer in software engineering best practices.
