Rockstar🎓
Top SchoolArturs Sosins is a CTO with 13 years of hands-on software engineering experience, leading Countly’s technology and product analytics platform since 2014. He combines back-end data processing expertise with front-end and mobile SDK work, having implemented core features for Countly’s server, web SDK and Android SDK. His contributions show a practical focus on reliable data pipelines, event processing, session management and user data serialization—skills honed further by work on geoip-lite to modernize geo-data handling.

Based in Latvia, he brings a measurable track record of turning analytics complexity into dependable, production-grade features.
