PROFESSIONAL EXPERIENCE

Temabit Software Development
QA Automation Engineer | August 2021 - September 2026 | 5 years 2 months

DAMS - Warehouse Management & E-commerce | 2022 - 2026
• Developed and maintained UI-focused automation using JavaScript and Cypress, using APIs for test preconditions, test-
data setup, backend validation, and cross-service assertions across complex warehouse and e-commerce workflows.
• Designed and maintained isolated, integration, and end-to-end automated tests covering inventory, orders, collection
tasks, shipments, stock changes, and synchronization between multiple services.
• Contributed to a shared Cypress automation framework used across multiple product teams, developing reusable
components and common testing approaches and participating in peer reviews focused on architecture,
maintainability, reuse, and prevention of duplicated implementations.
• Designed a scalable test-data allocation approach for inventory-sensitive tests after investigating multiple solutions and
collaborating with backend developers. Introduced dynamic product selection using 20+ configurable attributes and
temporary Redis reservations, enabling parallel execution and reducing shared test-data conflicts.
• Designed and implemented selective automated retries that rerun only failed tests in clean browser sessions while
preserving reports, screenshots, and artifacts from every attempt; added threaded Slack notifications and correlated
ReportPortal runs to simplify unstable-run analysis.
• Co-developed a custom Cypress-ReportPortal agent supporting structured scopes and steps, Cypress hooks, batched
logging, execution-state handling, and extensible reporting across multiple products.

• Redesigned GitLab CI/CD configuration with reusable inherited templates and Pipeline Inputs, simplifying test execution
and reducing duplicated configuration. Supported parallel execution, scheduled runs, frontend feature-branch testing,
reporting, artifacts, and cluster-based secrets management via Vault.
• Developed and maintained multi-layer production health checks for critical DAMS functionality, combining frequently
executed isolated API/UI checks with cross-system integration scenarios to continuously validate product health and
localize failures. Published isolated health results to an internal monitoring platform for engineering and business
visibility.
• Independently investigated cross-team service integrations for E2E automation, collaborating with engineers from
dependent product teams to understand system flows, identify appropriate APIs and validation points, and reuse or
extend shared framework components.
• Participated in automation planning and coverage prioritization with QA engineers and the Product Owner, applying
risk- and business-value-based selection. Proactively identified additional scenarios and edge cases and contributed to
testability during feature refinement, including stable frontend test identifiers.
• Drove adoption of shared automation tooling across QA teams through technical sessions, enabling QA engineers to
independently understand, execute, and analyze automated tests and providing reusable tooling for rapid test-data
preparation.
• Supported onboarding and knowledge transfer for QA/AQA engineers, sharing domain and automation knowledge and
providing ongoing technical guidance across complex business and integration flows.
• Actively contributed to a cross-team AQA engineering forum of up to ~20 automation engineers, researching and
proposing technical initiatives, contributing to shared framework and architecture decisions, presenting solutions, and
supporting adoption of common automation approaches.
Additional experience: production performance testing with Python/Locust; Zephyr test-management integration mapping
automated runs to test cases by ID; production-safe test-data cleanup and soft-deletion workflows; Elasticsearch-based
investigation; Kubernetes/Rancher operational troubleshooting.

KLUSHA - E-commerce / Warehouse Automation | 2021 - 2022
• Built and evolved a C#/.NET automation project, independently investigating underlying APIs and system interactions
behind UI-oriented business scenarios and automating them primarily through API/integration tests using xUnit and
RestSharp.
• Extended automation coverage with Playwright .NET for UI testing and implemented database-level validation and test-
data operations using ADO.NET and MS SQL Server.
• Created and maintained a Docker-based test execution environment and integrated ReportPortal for detailed automated
test reporting; used Graylog for investigation and troubleshooting.
• Continuously refactored and evolved the automation framework, introducing stronger SOLID principles, reusable
architecture, and maintainability practices as the project matured.
• Participated in the internal Automation QA competence center, researching technologies and automation approaches
and presenting practical implementations to other QA/AQA engineers.
