Professional History


Senior Software Engineer / Software Architect

UBS, Decentral Applications

Redesign the entire UBS credit system for new BPM, ECM and SOA based architecture using Enterprise Architect model with seamless integration into the existing core banking interfaces  take responsibility for  documenting all technical and application relevant topics of the  corresponding business case.

Design and implement central content management system for confidential documents, onboard and integrate first pilot applications using the new web-service. Present and educate about the new client confidentiality concepts for structured and non-structured data.

Analyse, design implement autonomous hi-throughput, 365x24 reliable, Oracle DB based data processing agents to feed the existing UBS trading systems capable of transforming heterogenous account and counter-party identification data into one unified partner model. Provide testing concept, perform tests and introduce all components in CH, AU, HK, SG, TW and JP.

Analyse,  design implement, test and introduce to production an innovative, secure caching system to shield core banking enterprise layer from transaction load generated by new algorithmic trading investment bank systems. Onboard investment bank applications on this new system.

Engineer automated transformation utility for J2EE Websphere applications to Tomcat and the automated Maven/Jenkins build, support junior and offshore developers in continuous integration topics, testing and productive integration.

Create and implement a convenient testing utility providing integration testing features for sampling, recording and simulating web-service service access to core banking services. This tool has been launched as own initiative and got very popular in use by offshore developers, contractors and employees working in home office.


Senior Software Engineer

UBS, Strategic Solution Program

Design, implement, test (performance, reliability) and introduce J2EE compliant connectivity for Websphere to access MQ based core banking systems out of web-applications. This comprised writing Websphere deployment and MQ administration scripts to assemble the component as package. Support in automated installations on several hundred of nodes and 3rd level support to all applications using the connectivity and the underlying XML core banking services.

Design, implement, test (performance, reliability) and introduce J2EE compliant connectivity for Websphere to access legacy CORBA based systems out of web-applications. This comprised implementing an own CORBA protocol mapper according to the OMG specification, scripting and packaging as mentioned above.

Design, implement, test (performance, reliability) and introduce J2EE compliant connectivity for Websphere to execute legacy UNISYS mainframe transactions with the required IPC communication. This included writing UNIX IPC agents in C to access single threaded legacy libraries out of multithreaded Java runtime.

Design, implement, test (performance, reliability) and introduce J2EE compliant connectivity for Websphere to HTTP/S based services auch as market data feeds for UBS Quotes. Help in integrating  further services such as e.g. ECM.

Design, implement, test (performance, reliability) and introduce central logging library for web-applications to reliably handle buffered audit events, operational errors and key performance figures relevant for capacity planning of all web-based applications.

Drive, co-ordinate and coach migration of around 100 application projects to the new SOA platform including analysis of the issues and fixing the Java code.

Resolve all connectivity, Websphere platform and security related issues in 3rd level support for all UBS applications accessing core banking services in CH. Provide comprehensive user manuals for developers and operators, transfer knowledge as presenter and instructor for best practice and patterns (J2EE / Unit Test). Run load tests using Load Runner and JMeter, analyze memory (GC) and UNIX resources. Detect and resolve concurrency issues using own written, specialized unit test driver.
