I build payment-switch applications at Fiserv using HP NonStop Tandem technologies, supporting the payments and cards domain.
I've worked with TAL, TACL, FUP, Enscribe, ISO8583, Tandem Himalaya, and Enform. My earlier Fiserv internship included Java, Spring Framework, Struts, and Tricentis Tosca, alongside a Data Science virtual internship with EduSkills Foundation.
