Hannu Parviainen

I'm an astrophysicist (working as an exoplanet researcher) with a background in Solar System and exoplanet research. My main areas of coding expertise are in Python (NumPy, SciPy, Numba, Pandas, Arviz, Matplotlib) and Fortran (parallelisation using OpenMP and MPI). I also have experience in OpenCL for GPU computations, and C and C++.

I had my first taste to programming by toying around with small BASIC programs for VIC-20 and C-64 as a kid in late 80's and early 90's. Later, in mid-90's, I learnt Pascal, from where I moved to C and C++. I also learnt some Java in the early 00's, but for the last 20 years I've mostly used Python and Fortran.
