Problem-solving with computational methods and software engineering.
As a trainee on the Cloud team, I tested CSC’s cloud services from the customer’s standpoint. I deployed a Julia application to OpenStack virtual machine on CSC Pouta and OpenShift container platform to CSC Rahti as a demonstration and documented the process thoroughly.

As a summer and part-time worker and research assistant at SAL, I have been responsible for developing multiple scientific software packages using the Julia programming language around mathematical models developed by the research group. Developing packages included interpreting scientific research, designing APIs, writing documentation, and creating tests. Packages used GitHub for the centralized repository, GitHub actions for automating testing, and document deployment to GitHub pages. I also have experience in Python, but these days I prefer to use the Julia language for its superior performance and modern features for scientific computing
