  • I'm currently a Staff Software Engineer at Quansight

  • My current interests in Scientific Computing include (see here for technical blogs):

    • Theory of Sparse Arrays, in particular, PyTorch sparse tensors support
    • Optimization of Triton kernel parameters
    • Interoperability of Array-like objects from various software
    • Algorithms and Implementations
    • Support Fortran 90 TYPE construct in F2Py

  • I have initiated and co-authored a number of open source projects with the following highlights:

    • RBC - Remote Backend Compiler
    • F2Py - Fortran to Python interface generator DOI, ships with NumPy DOI
    • SciPy - open-source software for mathematics, science, and engineering DOI

    and contributed to a number of open source projects (Heavy.AI, PyTorch, Numba, Apache Arrow, conda-forge, XND, SymPy, etc).

  • My background is in Scientific Research: Mathematical Physics, Nonlinear Waves, Mechanics, Systems Biology, Microscopy, Solid Mechanics, Optics, Scientific Computations, etc. CV@ERIS, ORCID, Scholar

  • 📫 How to reach me: Linkedin, GMail

  • Fun facts:

    • I have completed AoC 2019, AoC 2020
    • Estonian Champion 2006 in Dog Obedience (German Shepherd), currently training for Agility (Boston Terrier)
