Summary
👤
Senior🎓
Top SchoolKwaku Twumasi-afriyie is a Senior Client Solutions Specialist with a decade of hands-on experience designing and delivering payment and banking software across Africa and now based in Ulm, Germany. He combines deep e-payments expertise—from architecting multichannel payment platforms and merchant integrations to leading small developer teams—with client-facing consulting across finance and health sectors. At Deloitte innoWake and prior engagements he has translated complex regulatory and operational requirements into reliable web-based systems and innovation strategy for banks and fintechs. Known as a stubborn problem-solver who prefers technical rigor over bureaucracy, he thrives in intellectually demanding teams and tolerates politics poorly. His career shows a pattern of building practical, production-grade systems (internet banking, ACH/direct debit, messaging engines) that bridge legacy banking infrastructure and modern web services. He brings a pragmatic mix of engineering discipline, client empathy, and a willingness to roll up his sleeves to get hard integrations over the line.
