BIOMETRICS. I was developing a highly loaded biometric system that was available to 75 million users of the Sberbank Online mobile application. I have developed the following solutions: API (CRUDE), sawing monolith into microservices and creating them from scratch. I have also been involved in designing: databases, integrations, conceptual architecture, customer experience, product vision, user interfaces and much more.

SIEBEL CRM PROJECTS: Aeroflot, Rosbank (Société Générale), Sberbank.My role was not only to develop CRM functionality, but also to provide consulting services to the customer. I analyzed the requirements, advised the developers, and worked to improve the user experience. I also had a large number of user interface design tasks, since there was no full-time designer in the project.
