Okko is one of Russia's leading online streaming platforms, providing access to movies, TV series, cartoons, sports broadcasts, and TV channels via its website, mobile apps, and Smart TV. As a Senior Software QA Engineer, I owned the end-to-end quality of the native iOS application, ensuring a seamless, high-performance user experience for millions of subscribers. To manage the high volume of feature releases, I integrated AI-assisted workflows into our standard manual QA processes, significantly reducing testing bottlenecks. Key Achievements & AI Integrations: - AI-Driven Test Design: Implemented a pipeline utilizing LLMs to automatically extract requirements from Jira user stories and generate structured, edge-case-inclusive test cases into TestOps, reducing manual test design time by 30%; - Intelligent Debugging: Accelerated defect isolation by leveraging AI tools to parse and analyze complex Charles Proxy network intercepts, Kafka logs, and Firebase Crashlytics reports, identifying root causes of mobile streaming issues faster; - Smart Data Generation: Utilized generative AI prompts to rapidly create diverse mock data sets and complex JSON payloads for REST API and microservices validation via Postman; - Shift-Left Quality: Applied AI-assisted prompt evaluation to review early-stage product requirements and Figma designs, catching logical inconsistencies before development began; - Release Management: Led the manual validation of critical iOS releases via TestFlight, ensuring seamless integration of features across the Apple ecosystem. Tech Stack: - Mobile: iOS, Swift, TestFlight, BrowserStack, Firebase, Crashlytics, AppsFlyer, Charles Proxy, AppStore Connect; - AI/ML QA: LLM prompt engineering, AI-assisted test generation, RAG validation workflows; - API & Backend: REST/SOAP APIs, Microservices, Postman, SQL, Kafka, DBeaver; - Tools & Infrastructure: Git, Jenkins, CI/CD, Figma, Jira, Confluence, TestOps, XMind, Scrum.
