"I worked with Jaroslav on customer data analytics project
for our e-commerce customer. I really have to highlight Jaroslav's
quick orientation in customer's problems and data, plus his
understanding of goals we wanted to achieve. He prepared perfect
market basket analysis and was able to clearly and convincingly
define, communicate and document the outputs."
"I have worked with Jaroslav on time series forecasting.
I would like to highlight Jaroslav’s high level of professionalism
and his exquisite python programming skills. One can truly read
his code like a novel. His ability to quickly prototype solutions
to scalably process large datasets is impressive. His programming
was always with an end goal in sight, to produce an automated
solution for a given analytic task."
"I had an opportunity to work with Jaroslav for a couple of years
in ML team in an automotive industry and it has been a pleasure!
He always understands the problem and gets to the issue at hand.
He can document the whole project with ease and integrity.
He can deliver on time and present the result in a perfect way.
His personality is just as great as his work drive, I will
definitely miss seeing him around."
