: Experienced and knowledgeable software developer/architect within the banking/finance and telecom domains.
: My core background and interest is scaleable, networked and (highly) concurrent applications and systems. I have worked with the IP stack in general and protocols on top of that in particular, designing and writing backend services as well as multi-tier web applications.
I am fluent in Java and the J2EE stack, as well as a multitude of the major and minor frameworks and application servers. I have worked extensively with the C/C++ languages, both academically and professionally.
I have worked on linux, Sun Solaris, HP-UX and AIX and am capable in using and administering these (server-)platforms. And obviously I know my way around desktop Windows 🙂
: I believe in adherence to design patterns and best practices, in decoupling tiers by strong interface contracts and language and platform agnostic implementations and versioning.
I believe in code that is easily testable, reusable, changeable and extendable. I encourage using tools to quantify these metrics in a codebase and actively and systematically using same tools to raise quality awareness in the team.
I have worked in waterfall projects, agile projects and scrum teams, with test driven design and domain driven design. I have read and written monolithic requirements, epics and user stories, UML.
I strongly believe in and always strive to understand the business domain and language, to enable me to communicate and work efficiently and – if necessary – act as bridge between the business and the development team.
: I prefer quality over quantity. I take pride in responsibility and keeping promises. I enjoy working with smart, creative and humorous people. I continually strive to be one.
