Participiating in develop the product of inner business process management that allow to migrate a lot of logest routine processes to the automated system and significantly reduce a risks of much expensive missings.- Creation of business logic (Spring) and solutions with documentation (Jira) and presentations (Demo session) for users.- Working in short-term sprints and following Agile principles (by Jira tracking). Team support and creation of onboarding instructions for non-standard situations.- Implement low-level practices (Java core) to improve performance (Jmeter) and improve protection against attacks (Security SDLC).- Validate and investigate application level security and simulate attacks (Threat modeling via MS Threat Model, Checkmarx).- Mentoring on Java training programs and monitoring the assimilation of programs. Conducting technical presentations to share knowledge and improve code quality.- Participiated in designing some solutions that allow to enforce innovation consepts for varied and complex business logic based on Camunda BPM.- Implemented components with reactive programming based on Spring WebFlux for the highload parts that allow from worldwide. - Participiating in an event-driven consept to some services to reduce the number of connections.- Designing and implementing components that allow to generate SQL query from Java code using Jooq tool. Working with annotation based processors which help to generate some code like as Lombok.- Working with CI/CD with enterprise infrastructure based on industrial standards like as Kubernetes or OpenShift and defenetly with Jenkins or something like that.

Developing the highload distributed infrastructure for international retailing with distributed local servers based on own datacenters. The system links and integrates ordering system, delivering and workhouse accounting, integrating with external systems such as SAP, CRM of delivering companies, notifications and so on.Participiated in designing an architecture and its solutions that allow to enforce innovation consepts for varied and complex business logic based on Camunda BPM.Led a small team and mentored java developers to ascertain successful complation and had meetups fo improving skills and getting expirience.Utilized technologies are Java (Spring infrastructure), Kotlin, Spock (groovy) + JUnit 5, GitLab pipelines, microservices orchestration, Kubernetes + HELM

Took part in development of B2B e-commerce ecosystem. This product has services such as catalog, ordering, surveys, stock accounting. Possibility to deploy own SAAS infrastructure over kubernetes infrastructure in own clusters.Designed and implemented microservices components with reactive programming based on Spring WebFlux for the highload microservice, which works with high resolution images. Enforced an event-driven consept to some services to reduce the number of connection, which waited response what don't need in most cases.Analyzed system flow, data usage and work processes for investigation problems area and suggest solutions.Supervise and mentoring junior java developers to ascertain successful completion of them projects.Utilized technologies are Java (Spring infrastructure) + WebFlux, Kotlin, Spock (groovy) + JUnit 5, GitLab pipelines, microservices orchestration, Kubernetes + HELM

Worked on business process automation which allowed to work with documents, reports, planning and delivering of commodity-material assets.Led a small team with kanban management and designed architecture and solutions with microservices based on existing infrastructure. Designed and implemented full workflow from develop processes to deployment.Utilized technologies are Java (spring boot infrastructure), Kotlin, Cuba Platform, Spock (Groovy), Custom task tracking like Jira, GitLab + Jenkins, Embedded C++

Development and implementation of application software for programmable logic controllers (PLCs). Creation of an automated workstation based on SCADA systems.

Participiating in developing the big information system which allow to collect and process data about condition of buildings and structures. Also that system has a lot of modules which works with IoT devices, BPM processes based on statuses of IoT devices, monitoring submodules.Designed architecture and imroved modules which worked with IoT devices. Managed a small team and used short-term agile practice.Used technologies are Java (spring boot infrastructure), kotlin, C, GitLab pipeline, Docker

Developing the monitoring and control system of energy resources for governement organization which have to save resources. The system works with GPS tracking and custom BPM.The system has based on Kotlin/Java monolith and worked on VPS. Organized and prepared full CI/CD flow from development to deployment. Used one week sprint for develop looks like agile. Managed a small team with BA, QA and Art designer.Technologies stack is Java, Kotlin, C#, VueJs, GitLab pipeline, Docker
