Our language learning app/webservice has +1M downloads and now we are looking to build the next version.
We are a Swedish company, but Misha our TechLead/ CTO is +50, PhD in applied maths from Russia, but lived in Canada for last 15 yrs. So communication can be in both English and Russian.
We would prefer daily or monthly rate, rather than a high hourly rate.
Could this be of interest?
