Implemented comprehensive automation smoke test suites Optimized the automation test suite structure, resulting in a fourfold reduction in test script development time and enhanced framework maintainability. Restructured the regression model to isolate microservice-specific tests, streamlining the validation process and cutting manual testing time by 30% per release cycle. Developed comprehensive testing guidelines for manual, mobile, and automated workflows, which increased functional testing speed by 30%.

This a retail project. Execute functional, integration, regression, and smoke testing on applications with different architectures: monolithic and microservice. Tested Point-of-Sale (POS) systems, including specialized hardware, embedded firmware, and checkout software on Debian Linux. Conducted integration tests with payment gateways and billing systems, ensuring secure and accurate transaction processing. Worked in an Agile environment with 2-week sprints, actively participating in all Scrum ceremonies

A high-load Fintech project Performed integration testing for business workflows using Camunda BPM and verified Apache Kafka messages. Designed and organized a regression testing model for critical system functionality to ensure stability during release cycles. Validated complex financial data in PostgreSQL, ensuring accurate information processing from various integrations. Provided L2/L3 technical support by analyzing user reports and identifying root causes of system errors using Kibana logs.

A project focused on testing complex integrations between cloud-based IP telephony (VoIP) and external business ecosystems. Developed a comprehensive Postman collection for automated API regression testing, ensuring the stability of integration services. Performed end-to-end integration testing between IP telephony services, CRM systems, and marketing analytics platforms (Google Ads). Analyzed user stories and requirements to design comprehensive test scenarios for API-based exchange services.

Advising key and VIP clients on solving emerging problems online and offline. Conducting more detailed diagnostics of API requests using Kibana and Postman. Transfer of applications to testers and developers via Redmine Diagnostics of direct integrations via the UNIX terminal with the help of GREP queries Reading application logs (mobile softphones and PC versions) Working with documentation in Confluence
