- Description: Company develops a multi modules stock exchange solution. Optimizing current architecture of the solution, publishing documentation and implementing modern technologies.- My achievements: I’ve designed component diagrams about the current infrastructure and published recommendations on what technologies and architecture patterns can improve the system.- Using: C4; UML; Analytical skills; Technical Leadership; Communication skills

- Description: Analize current solutions to find discrepancies to company’s needs, laws and world trends. Work with enterprise architect, information security department, product owners and engineers. Publish recommendations and build roadmaps and advocate it to all stakeholders. Monitor the development process, consult engineers, communicate to different departments to allow my solutions to be developed and implemented in time. Calculate the effectiveness of the solution. Time to time I still write the core parts of the solutions to be in the real world.- My achievements: I've completely refactored the solution and migrated it to Kubernetes cluster to be scalable, secure, fault tolerant and highly available. I've implemented a mechanism to generate new services by template so it allows teams to create production ready service around 400% faster.- Using: TOGAF/Archi/Analytical skills/Technical Leadership/Communication skills/Presentation skills

- Description: Company has many systems to provide sales. A lot of systems are set of program components. For the last time I have been participating in meetings with product owners where we design business processes, gathering and analyzing business requirements with business analysts and designing a component interaction and component requirements. Time to time I review code, help developers with software architecture, help DevOps engineers with infrastructure and talk to designers about UX. - My achievements: I've completely designed few solutions which are parts of a one ecosystem. Solutions are sets of microservices which interacts each other through REST API and Kafka. I've implemented mechanism to generate new service by template so it allows to create production ready service for 5 minutes. I've refactored architecture and implemented new technologies to one system. Earlier I've gathered a team, introduced a development process in Java stack, designed deployment and delivery processes. - Using: Java/Spring/REST/Kafka/Vaadin/ReactJS/Oracle DB/PostgreSQL/Jenkins/Kubernetes/Microservices Architecture/Leader Skills/Analytical Skills
