Senior🎓
Top SchoolHeiner Kallweit is a program manager and seasoned technology leader with 12+ years of experience combining hands-on engineering, technical account management and agile delivery leadership of teams up to 45 people. He specializes in cloud-native, process-driven software and business process automation (BPMN/Camunda), delivering multi-cloud (AWS/Azure) transformations and project turn-arounds while engaging stakeholders up to C-level. His background spans payments, risk & fraud prevention and integrations (MuleSoft, SAP BRIM), grounded in early systems and kernel-level development—he has contributed fixes and feature enhancements to prominent Linux trees including torvalds/linux. Heiner blends technical depth from an electrical engineering and industrial engineering education with commercial pragmatism, routinely translating complex hardware- and cloud-level constraints into dependable production systems. Pragmatic and process-oriented, he is as comfortable refactoring kernel drivers as he is steering large-scale digitalization programs.
