Stanley Mills
@stanleymills
Senior client technical support engineer combining mainframe expertise, production support, and training to ensure FinTech reliability.
What I'm looking for
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.
