Jaan Tollander De Balsch Email & Phone Number

Currently, I'm a junior application specialist in CSC's Computing Environments team, which manages user-facing installations on CSC's HPC clusters. My responsibilities include developing and maintaining the Julia language environment, containerizing user applications, and improving user workflows. Previously, I wrote my master's thesis regarding monitoring and analyzing parallel file system usage on CSC's Puhti cluster. As a trainee, I worked in CSC's Cloud team, which provided me with experience in CSC cloud services, OpenStack virtual machines (Pouta), and the OpenShift container platform (Rahti).

During my studies, I worked as a summer and part-time research assistant at the Systems Analysis Laboratory (SAL) at Aalto University. At SAL, I wrote multiple scientific software packages using the Julia programming language around mathematical models produced by the research group. Developing software packages included interpreting scientific research, designing APIs, writing documentation, and creating tests. We used GitHub for the centralized repository, GitHub actions for automating testing, and document deployment to GitHub pages. I also have experience in Python, but I prefer to use the Julia language for its superior performance and modern features for scientific computing.
