Callsign.
Built the company's flagship product, the Intelligence Platform that detected fraudulent logins in banking applications (web and mobile apps) based on user’s biometric data collected.
The platform consisted of message handler components as well as Data Science models and my task was to make sure these components can work together to detect possible fraudulent transactions, in real-time. The platform handled larger than usual messages at the rate of 1,000 messages/sec. Used Akka HTTP and Akka Stream for data processing applications and Kafka as the message broker.
