About me

Welcome to my page. I am a data professional for Qimia. I like to tinker with programs and try to make life easier for others and myself by creating software. Software is often on my mind, and I love to discuss ideas.

Experience

The type of work I have been doing:

• Maintaining a legacy high-performance expert-system
• Natural language processing in a healthcare context
• Maintain and develop a fast single-purpose graph database
• Datalake design and data pipeline development
• Help create an (internal) Airflow-alternative which is highly integrated in Apache Spark
• Machine Learning model development and optimizing inference performance for a Fintech startup
• Topic modelling and cluster analysis
• Predictive maintenance using signal-analysis
• Helping a delivery platform with optimizer- and backend-development

Skills

Programming languages

Professionally: Java, Python, Scala (and plenty of SQL)

In the past: Matlab, C, Prolog (at university)

In my spare time : Rust, Go, Elm, Julia, Vala (and with interest in many many more, I like to geek out about them from time to time)

Tech

I have been using different flavors of the Linux operating system (Redhat/Fedora, Ubuntu, Debian, Suse, Arch) since 2008. In a long distant past I also helped manage some Microsoft Windows machines using Windows Server 2003.

Through project work for customers, I work extensively with the GCP, AWS, Azure cloud-platforms and especially their data oriented services. My own projects run on Hetzner and Transip and I enjoy hosting things locally.

There are a couple of larger pieces of software I helped operate at one point: PostgreSQL, Kafka, Clickhouse, MySQL, Hadoop (Hortonworks, Cloudera).
