PROFESSIONAL EXPERIENCE

Lead Performance Engineer | Julius Bär & Co. Ag (BAER), Bank, Zürich, Switzerland

Sept. 2010 – Present

Brought on to apply specialized experience in performance engineering to improve operations in the department, and serve as a gatekeeper at the private bank to ensure applications fulfill the requirements of highly-affluent clients with millions in assets. Recruited and developed a team of top-performing engineers to manage non-functional requirements and ensure reliability of applications to maintain optimal performance for clients’ customized accounts.

KEY ACCOMPLISHMENTS:

  • Led infrastructure lifecycle performance testing project, and demonstrated the potential of reducing hardware costs by 50% through simulation of the realistic load pattern.
  • Successfully built up performance engineering services, and improved application response time of business critical applications by transforming the monitoring from working as reactive to proactive, and introducing new ways of end-user based monitoring.
  • Directed a group of performance-testing experts to ensure fluid onboarding of several thousands of Merrill Lynch customers. Introduced risk-based engineering to streamline the process of prioritizing the performance testing of over 70 applications, ultimately ensuring effective management of high volumes of data.
  • As part of Master’s thesis, analyzed the development processes to create a platform and close gaps in security and software development chain; recommended the implementation of the secure code analysis platform Checkmarks to fulfill the requirement.

 

Lead Competence Group Test Engineer | Swiss Life Ag (SLHN), Insurance, Zürich, Switzerland

Aug. 2008 – Aug. 2010

Quickly on-boarded to support the company in improving performance testing, and testing of automation tools in projects to enhance the reliability of applications and fulfill performance requirements. Progressed to lead engineering activities and recruited, developed and managed a team of test engineers to implement new testing methods and process improvements.

KEY ACCOMPLISHMENTS:

  • Boosted the efficiency of building test cases by improving the UI in replacing a former HP system with Tosca Suite, which allowed those without programming backgrounds to facilitate testing, and proactively address issues either before they reach the client, or immediately once it affects the client.
  • Incorporated continuous improvement for the testing suite, and its maintenance and user support by working out performance test concepts, simulating tests, identifying bottlenecks and improving reliability of applications.

 

Performance Test Manager | Atos Origin (ATO), Telecommunication, Düsseldorf, Germany

Sept. 2003 – Jul. 2008

Recruited to support the IT outsourcing company and manage the evaluation and rollout of performance tests and monitoring suites. Reviewed functional and non-functional requirements to lead the team in implementing all actions required to deploy application performance tests and ensure reliability.

KEY ACCOMPLISHMENTS:

  • Contributed to increasing revenue by implementing an end-user monitoring system, and supported the manager in creating SLAs to effectively calculate availability in performance metrics on a monthly basis, which provided a more transparent view of actual costs to charge E-plus for the Atos service.
  • Norman Load Testing: Directed the performance testing team to develop a strategy to effectively identify performance bottlenecking and improve functionality of the Order Management application; ultimately enhancing the process of transitioning customers into new contracts or accounts.

Lead Software Development & Consulting | Isardata / Spirit SE, Consulting, Wolfratshausen, Germany

Aug. 1999 – Aug. 2003

Recruited to transform the Visual Basic based test automation prototype to a product which could be sold to customers. Conducted the design, implementation, testing and roll-out of the new test automation framework called TestOffice.

KEY ACCOMPLISHMENTS:

  • Led software development stream, implemented new test automation framework user interface in Java, implemented C++ based floating license server.
  • As part of the Bachelor’s Thesis designed and implemented the test case definition language TCDL which allowed creation and execution of automated test cases without any programming language knowlege.
  • Successfully released several versions of TestOffice, trained customers and supported customers during product integration
