Klaus Rubrecht
Hi! I'm a freelance software engineer. I love using the best tools out there to build awesome solutions. This includes Ruby On Rails, NodeJs, Cordova and many others ...
About
Tools
I love to use Ruby on Rails or NodeJs on the back-end, on the client side I like building user friendly ui's with React, Angular or just plain old JavaScript (or CoffeeScript). I've most experience with PostgresQL as database but have used MySql as well, I've also worked with Redis, Memcached and MongoDB. I use Vim as editor. But in general I strongly believe one should use the tool best suited for the job.
Best practices
I'm a strong believer in testing as a foundation of strong software. Core business logic should always have 100% coverage. I always strive for clean and maintainable code using object-oriented practices and principles, applying desing patterns (only when they are needed). I love to expand my horizons, because best practices go hand in hand with continuous learning and keeping up to date with the latest advances in the relevant technologies.
Communication
It's very important to have a clear overview of progress and direction, that's why I think communication is key. Agility means small incremental steps, continous integration and deployment, daily status and clear requirements. These are all principles I adhere fondly to because good communication can improve the flow and speed of a project drastically and ensure there are no unpleasant surprises.
Education
The foundation for my development skills grew from a strong analytical background. I obtained a masters Engineering degree in Applied Phyics and a degree in Mathematics from the University of Ghent (Belgium) at the same time. During my final masters year I studied a brief stint abroad at NTNU Trondheim (Norway). As a result of this education I'm not afraid of tackling difficult problems by using abstract and efficient algorithms. This is an important advantage to have when optimizing and scaling applications.
Personal
In my spare time you'll find me behind the piano, running in nature, playing tennis, travelling or spending time with family and friends.

Welcome
I’ve been planning to do this for a while, but now it’s real. As a technical specialist you sometimes encounter problems where a solution isn’t a given thing. A problem where you are lucky that that one coder on the otherside of the globe ran into it before. You’re really...

FLIR ITS
FLIR ITS is a manufacterer of embedded video detection thermal camera's for traffic applications
While working on the detection algorithms there was a growing need for internal tooling, so I developed an automated build server running the detection algorithms on large batches of annotated images. The detection team can now happily make releases and make sure their detection performance is up to par. This included establishing a connection with their internal LDAP server for authentication, an providing detailed results analysis in a dashboard.
