IDAP Group is a Ukrainian web and mobile development company, whose tech team has grown from 10 to over a 100 professionals under my supervision. As a CTO I managed the technical decision making, architectural decisions, grew and expanded the engineering culture in the team leading by example and creating and drafting out the approaches to be used during development. As a trendsetter within the company I've successfully improved team communications and created a heart-warming atmosphere within the company using valuable feedbacks from the team members. As a mentor I taught and helped out in various ways both the newcomers and experienced developers, sharing insights, performing code reviews, doing 1to1s, etc. My personal pride is that at least 3 of my ex students and employees became CTOs themselves.As a developer I wrote mobile applications using DSP algorithms for video, image and audio processing, scalable backends with both restful and real-time communications, architectural solutions to handle exponential load, implemented neural networks used for tagging and image segmentation and processing.
