That's me

Sebastian Korfmann, 30 and from Germany. I wrote my first program during a school project over a dozen years ago. After a couple of years trying out different things, I came across Ruby on Rails back in 2006. I was immediately sold, built some private sites and attended the RailsRumble 2007. As it was just a hobby for me, it took another two years before I applied for my first professional Rails-Job in the mid of 2009. So, that were my early days. Here I am now - a self-taught Software-Developer who was fortunate enough to meet the right people which guided me in the right direction and taught me tons of useful stuff.

Companies I've worked for

Ubilabs


My first employer in Hamburg and one of the best companies in europe when it comes to geo-projects. Had a great time and learned so much while working with them.

Tmp8


A small company from Hamburg, specialized in building sophisticated web projects. They strongly believe in extreme-programming, therefore we've done pair-programming most of the time. I really enjoyed my time there.

9flats


My first real freelance gig and as far as i know, the first german competitor to airbnb. I worked in a large, distributed team and was especially hired for a geo-data project.

Mds


Another interesting freelance project. We've built a traffic information system for ports, by combining several data sources to get the overall picture of whats happening in a specific port.
