ABOUT ME
Software Engineer
EXPERTISE
Java expert help Java - 15 years experience
Although Pascal was my first love, Java is in many ways the best programming language I know.
No icon Xslt - 5 years experience
Michael Kay, the author of the best Java XSLT processor (Saxon) and a large part of the XSLT specification, also wrote the best books on the subject. Very accessible, very precise, very thorough.
No icon XML - 10 years experience
XML didn't live up to its expectations, but I still like it.
Sql expert help SQL - 10 years experience
SQL is useful. What else can I say?
Scala expert help Scala - 4 years experience
After the initial excitement wore off, I feel that Scala is not as huge an improvement over Java as it's made out to be (especially since Java 8 introduced lambdas), and Scala has a few disadvantages: compilation often takes much longer and is less incremental, and some language features can actually lead to reduced code quality.
Python expert help Python - 4 years experience
I once had to work with Zope and didn't like it, but Python was love at first sight. I never had an opportunity to build large Python applications though.
Mysql expert help MySQL - 10 years experience
MySQL was the first SQL database I worked with, and it's still my favorite, although I also enjoyed working with PostgreSQL and Derby. Oracle is an old-fashioned monster.
Android expert help Android - 2 years experience
As far as building apps is concerned, I prefer Android to iOS, mostly because I prefer Java to Objective-C.
Php expert help PHP - 4 years experience
Built several small websites. Maintained DBpedia code (information extraction) before we switched to Scala.
Git expert help Git - 4 years experience
Git is fast, robust and simple. If you're coming from server-based versioning systems, you may need to somewhat change your thinking though.
No icon Spring - 5 years experience
Want to learn how to build super-clean and well-designed Java frameworks? Read Spring source code. Best code base of all open-source projects.
No icon Soap - 5 years experience
SOAP is never simple, rarely about objects, and doesn't provide access. It's not great as a protocol and even worse as an acronym. I debugged and maintained SOAP interfaces for dozens of large financial institutions and want to help the unfortunate souls who have not yet migrated to JSON. ;-)
