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.

I was working in SoftServe for 3 months on Junior Java Developer position at Cisco Network Planner project. I was a part of a team which consisted of 5 back end developers, 3 front end developers, team leader and project manager. The team was outsourcing for Cisco company. My main responsibilities were finding a source of bugs and if they were on back end to fix them. Also adding additional features to the API as well as writing tests. I was performing all tasks running API on Windows and in Oracle VM using Ubuntu. Also I was helping the team to find the ways to encrypt a database and some manual testing of the product.
