Together with iHealth Finland we created machine learning algorithms forecasting the spread of pathogens. Doctors and pharma companies use our web-based interface to monitor when and where in the country epidemics are likely to occur.

They provided advice, UI design, frontend and backend code, cloud infrastructure and data analysis algorithms. All on time, very communicative and flexible with adjusting features as the project went along. It’s reassuring to know your product is in the hands of real professionals. Impeccable work - I can recommend them without hesitation.
