What I'm looking for

I'm looking to build reliable, scalable products through QA automation, CI/CD, performance validation, and hands-on ownership of testing processes.

At Foretellix, I author automated testing for an AI assistant and self-driving-car management platform, validating LLM responses and benchmarking Elasticsearch and ClickHouse performance.

I've contributed 41% of my team's automated suite, built Jenkins regression pipelines, and led database scalability validation across millions of test executions and 20M simulated vehicle scenarios.

As TA-39's first dedicated QA hire, I built the QA function from the ground up with Jira workflows, Pytest and Playwright coverage, and GitHub Actions pipelines that cut delivery time by 30%.

I also bring backend engineering experience building C++ CRUD APIs and Spring Boot REST APIs, with a focus on reliable releases, actionable bug reporting, and practical process design.
