Created DDD model of workflow and tools providing use the same domain logic for AWS, Spring Stack, GCP without changes. Thus,migrated Cloud model of complex stream handling from Spring environment to AWS no server model. Initiated and created testing tools and principles within TDD/BDD paradigm providing incremental Unit and integration testing in real conditions,predict behaviour in concrete situation, estimate and predict performance from component to upper level. Create tools and API improving performance of structured data steaming by means of applying proper Java ,Object to Stream Mapping,NoGC (Native Java memory) leaded to zero GC expenses, 80% win in performance. Created unified messaging layer and API, leveraging DDD mode build,providing notification, data transfer and handling over customised mechanisms, (as ActiveMQ, RabbitMQ, SQS), data grid and notification mechanisms as Firebase and Hazlecast. Created API and framework for automated mount of distributed, hierarchic reactive workflow of neural model, type oriented routing, customised channels and messages. Create algorithmic core for NLP to handle large test volume collected from mobile devices and sites crawling, providing fast data retrieve,recognition of conversation context, theme , building predictive dictionaries; Add ins to Spring Boot providing transparent model cut for separated JVM, dynamic bean definition , loading from remote sources, type oriented reactive processing and routing, which enabled reuse the same monoliths in distributed reactive model Designed and engineered solution integrating ASP.NET facade with EJB services Created Light weight Service location and discovery in VPN with LB, adapted for RMI, Spring REST, messaging frameworks.

Участие в крупнейшем международном аэрокосмическом проекте. Опыт работы с иностранным заказчиком в качестве архитектора. Работа с большим объемом legacy. Вырастил всего двух, но очень толковых разработчиков, за работу которых не стыдно.
Хочу погрузится в проект на 100%, активно участвовать в его жизни и не быть банальным исполнителем команд сверху(снизу, сбоку). Остальное как обычно: Профессиональный рост. Можно стартап. High-load cloud based distributed application
