Dierk König, 1968

Senior Software Architect and Coach

Objective

Assisting our customers in successfully creating software solutions that meet their

requirements and exceed user expectations.

As an architect, I'm happy to take responsibility for non-functional requirements like stability,

extensibility, performance, scalability, maintainability, testability, and correctness. As a

coach, I enjoy helping teams and individuals to achieve extraordinary results and to

continuously improve through collaborative learning.

Profile

A Senior Software Architect with extensive technological background who has come to the

considered opinion that architecture is never finished until it has become live in the minds of

the development team and is working in production. To this end, I strive for simple, solid

concepts, clear purpose, and the highest standard in software craftsmanship.

Being an early member of the agile developer community, I have contributed to making this

idea a reality through both running projects in an agile manner and sharing experiences in

talks and publications. I have helped in advancing the practices of customer collaboration,

agile planning, test automation, test-driven design, code katas, pair programming, continuous

integration, refactoring, incremental software construction, and retrospectives.

It is my particular strength to alleviate major project risks that habitually arise from any of the

above practices not being obeyed.

Professional Achievements

Shaping the open www.pillarone.org Risk, Rating, and Reserving platform for the insurance

industry as its technical architect. My contributions included laying out the general

architecture and guiding a mixed team of Canoo and customer engineers through the

implementation. Moreover, I coached the team in agile development practices and various

technological issues.

I facilitated a customer collaboration scheme that addressed major communication issues

and is meanwhile deemed indispensable for the project's ongoing success.

Development of the award-winning Canoo TIPP! game, where I laid out the general

architecture and the initial implementation with a team of six Canoo engineers. I prepared the

timely submission and presented the winning solution.

Development of a Struts/JSP based intranet application for managing the corporate reporting

and account structure at SwissRe. I worked as senior developer while coaching a mixed

team of customer and Canoo engineers through all project stages after an initial

requirements gathering until final successful delivery. The introduced approach to project

planning and controlling, release management, test automation, continuous integration and

team collaboration have become a role model for subsequent projects.

Founding, setting up, co-developing and managing the open-source Canoo WebTest project

webtest.canoo.com. The project was invented in 2001 as the first powerful open-source

solution for automated testing of web applications. It has become very popular and is used all

over the world in companies ranging from small shops through academia up to a number of

fortune 500 and government organizations.

Author of the best-selling "Groovy in Action" book, Manning 2007, with translations into

German, Japanese, Chinese, and Korean. Foreword by James Gosling.

From the Amazon reviews: Johannes Link "It is a Gordian challenge to write an interesting

and readable book about nothing but a programming language. Dierk König and his co-

authors actually did succeed in cutting the knot. They even accomplished much more: they

added lots of insight about object orientation, programming language design and good

software development. As long as I only had the PDF available, it served me as THE

reference for all my questions about Groovy. Now the printed copy makes my commuting

time worthwhile. Cover to cover. 700 pages of computer LITERATURE."

John Sanabria " [...] I consider it as much as a Groovy bible."
