Dr Alexander Bunkenburg

Scala Java web developer

Technically: Scala, Java, web. Role: mainly development. Prefer freelance. Modern informal company style. Prefer companies that make their own engine, over consulting companies. I value the ethical aspect: using technology to make lives better. Interesting: cryptocurrency, energy, or science.

skills and tools

soft skills

teamwork I enjoy the egoless team work that I experienced in infojobs and netcentric.
independent I am able to work independently and remotely. I'm accustomed to distributed teams communicating via tools like slack and skype.
research I know research from my time in Glasgow and some POC that I made as developer.
teaching I enjoy teaching. I did it in Glasgow and still do it sometimes, whether it's programming or my hobbies.
mentoring At netcentric, I was mentor for junior colleagues.
methodical rigour My colleagues often value my methodical rigour. That's why infojobs put me in charge of versioning and code review.

interface

HTML5
XML, XSL/T, XML schema
CSS
JSON, JSON schemaI used them for survey data and non-deterministic execution of javascript.
Java Swing

tools

IntelliJ IDEA, Eclipse Recently, I seem to have switched from the latter to the former.
maven, sbt After shell scripts and ANT, these are better.
JUnit, ScalaTest With experience, I have come to value the peace of mind of automated tests, especially for algorithmic stuff.
Atlassian tools JIRA tickets, Confluence wiki, ... Before I program: Is there a ticket for this? Is there spec? Is there a branch?
Docker I use docker and docker-compose for repeatable environments.

source control

git on bitbucket, github, usually with policy gitflow. I trained git beginners.
perforce I was in charge of source control at infojobs. First designing the branching policy, then enforcing it.
subversion, cvs Branching and integrating are poorly supported.
