Résumé

Finnish math PhD machine learning expert and Python developer. Specialized in deep
learning in computer vision and NLP, RNNs and generative models. I use mostly PyTorch
and Tensorflow, in addition to the usual scientific computing stack.

See my Github for some of my open sourced code, LinkedIn and list of publications.

TOOLBOX
● Python and especially Pytorch, Tensorflow (both since release) + Python scientific computing
stack
● Expert in Convolutional Neural Networks (mostly for Computer Vision), Recurrent Neural
Networks (NLP, time series), unsupervised/self-supervised learning and generative models
(GANs)
● Distributed training/ high performance computing on GPUs and TPUs on GCP, Azure, AWS cloud
VMs/ Docker
● Highly proficient in several areas of mathematical programming
● Agile (Linux, git, GitHub, Slack, project management tools)
