What I'm looking for

I’m looking for a role where I can lead production support and technical implementation for mission-critical applications, mentor teams, and translate complex systems into effective training and reliable go-lives.

I’m an IT professional experienced in application development, production support, and implementation, backed by strong technical, management, analytical, and communication skills. I bring consulting services and training experience, focusing on building partnerships, influencing collaboration, and fostering accountability.

At Fiserv, I provide analysis, maintenance, training, and production support for a FinTech product suite, partnering with cross-functional teams through preparation, go-live, and ongoing support. I also lead a team of support engineers to ensure timely case resolution for white glove clients and deliver business intelligence support for top institutions—driving a 63% reduction in incidents.

I improve reliability through disciplined execution: procedures that reduced service and support defect backlog by 27%, and pre-release readiness management that resulted in fewer opened new incidents. I’ve trained associates in customer relations (37% increase in positive surveys) and developed web-based associate training for ServiceNow Knowledge Base, while resolving complex Mainframe issues that contributed to a 23% reduction in downtime.

Earlier in my career, I designed and supported applications across zOS, VB.NET, and TIBCO, translating business requirements into production-ready solutions. Before that, as a Staff Software Developer, I worked on electronic billing/payment and paper suppression capabilities generating an average of 10 million monthly electronic bill presentments and enrollments, and I’ve also supported mentorship and training through a sales and training consulting role.
