First encountered bank processes as a quality engineer, then switched to system analysis and gradually became a software developer.Within a team, tried acting as a tech lead: wrote manuals, established teamwork processes and trained new employees.• Implemented an event-handling pipeline on Kafka (Java SE 11, Spring Boot, Kafka Streams, Vavr, JdbcTemplate, Oracle 19c, JUnit, Maven, Docker, TeamCity, Ansible, AWX)– Developed a container-based application that filters Kafka topic and calls a REST API (SAS RTDM) to communicate with customers according to actions taken by them in a mobile app. Filter settings were read from Oracle DB and transformed into a graph representation to control customers' state transitions– Set up Docker image building from a source code in TeamCity, rolling out on test and production environments with Ansible in AWX– Communicated within the team: discussed requirements with a business analyst, suggested test cases to a test engineer, conducted code reviews with other developers– Estimated delivery of project milestones, tracked progress in Jira, wrote documentation in Confluence– Improved the testing process: set up Confluent REST Proxy on a test environment to speed up functional testing• Developed over 15 REST and SOAP microservices for an enterprise service bus based on IBM WebSphere Application Server (Java EE 8, JAX-RS / JAX-WS, Oracle JDBC, Gradle)– Set up code generation based on API specifications to reduce a level of bugs during development (OpenAPI 3.0 / Swagger 2.0 / WSDL+XSD)– Used SoapUI to create mock services, Postman / Insomnia / SoapUI / curl to test invocations and Fiddler to monitor traffic– As a tech lead, conducted code reviews of my teammates' work in BitBucket– Improved the development process: migrated teamwork from a proprietary IBM RDi (Eclipse) IDE to IntelliJ IDEA

• Wrote requirements for 20+ projects aimed at improving cross-selling in Operational CRM (Java, Pega, Oracle DB) and Analytical CRM (SAS, Informatica Power Center, Oracle DB) banking systems, integrated with the core ABS Equation (IBM iSeries, AS/400, DB2).– Estimated and gathered requirements, communicated with related departments– Prepared documentation and led a process of a compliance approval (business requirements, architectural visions, functional specifications)– Supported an integration and acceptance testing process, created test scenarios and manuals– Investigated issues during production as the 4th line of tech support• Implemented over 30 decision diagrams for Pega CDM (SIMPLE, XML)– Organized teamwork: moved a source code to Git, automated branching and merging with Bash scripts, created a manual on Confluence and trained development and testing teams to work in the new process• Implemented 5 decision diagrams for SAS RTDM and SAS MA (SAS BASE, SAS DS2)– Solved a performance issue: after analyzing a synchronous integration between two systems that was causing timeouts, concluded that it could be safely replaced with an asynchronous one

• Developed a framework for an automated testing, managed by HP UFT (VBScript, Oracle PL/SQL)• Conducted functional and integration testing of OCRM and FLECS banking systems (Atlassian Jira, HP ALM, SoapUI, Oracle DB)

• Performed functional testing of FORIS OSS billing system and trained over 10 new testers (Microsoft TFS, SoapUI, Telerik Fiddler, Oracle DB)

• Developed a web UI for Nagios monitoring system (JavaScript, Kendo UI, Perl, Apache HTTP Server)• Monitored the availability of video surveillance and fire alarm systems

• Performed a functional testing of FORIS OSS billing system (Microsoft TFS, SoapUI, Telerik Fiddler, Oracle DB)
