Working across a three-product fintech ecosystem (Hangipara, Hangikredi, Hangikredi KOBI), I own web/mobile automation quality for real-time data, funnel-critical flows, and rule-heavy business journeys while actively contributing to R&D initiatives.

• Strengthen E2E regression coverage for listing, filtering, application, and SME-focused business logic across Hangipara, Hangikredi, and Hangikredi KOBI.
• Contribute to R&D projects by exploring AI-assisted testing, prompt-based workflows, and small POCs that help mature team practices.
• Mentor QA teams and support quality culture through standards, DoR/DoD clarity, and practical training.
• Continuously monitor automation systems, runners, and CI/CD pipelines with alerting and automated mail notification flows.
• Build low-flakiness Web UI E2E with Playwright (TypeScript, POM/fixtures); support Android/iOS automation with Appium + Java + Cucumber and Maestro adoption.
• Validate socket/streaming payloads for real-time market data screens, cross-checking with Investing, TradingView, and Yahoo Finance plus deep API + DB verification.
• Run end-to-end performance and load testing, surfacing results in Grafana dashboards so bottlenecks stay visible and shareable across the team.
• Automate SEO quality checks and build GEO (Generative Engine Optimization) flows that measure content visibility not only in classic search engines but also in generative AI engines like ChatGPT.
• Develop an agent-based testing approach: generating test scenarios and test code through agents over an MCP (Model Context Protocol) server, then spinning up and running suites automatically.
• Build an end-to-end feedback loop where agents automatically open and route tickets on failures, shortening triage and resolution time.
