I have been building software for more than a decade. Three projects out of many I worked on:
Worked as team lead on design, implementation and certification of a VISA 3-D Secure Merchant PlugIn (MPI). This MPI was the first one on the german market, which was certified by VISA International.
Worked as team member on design and implementation of an e-payment system. It's hosted as SaaS (Software as a Service). A number of large german banks are licensees and use this system for providing PSP services to their business customers.
Project for TQ-Systems GmbH. Development of web apps and hybrid mobile apps with a single source. Consulting and concept, toolchain development and prototyping.
Sonoday creates an online marketplace for host-read podcast ads. Right now, Sonoday is in limited preview release with select Brands and Podcasts.
Consultant and developer for building a data warehouse system that clears bank card transactions. It's an in-house project of a financial services provider focused on services for electronic payments, like bank card issuing, operation of ATMs and operation of payment networks.
I am a full-stack developer.
No matter if it's databases, business logic, middleware, web frontends, graphic design or mobile apps – I can help you to move your project forward. Specifically if you are facing challenges that require a vertical drill through the whole stack.
Currently, I can only accept new contract work for small part-time projects. In case you want to get in touch, please find my contact data below.
