Hi, I'm Dmitry Yarygin 👋

QA Engineer with 15+ years of experience breaking, testing, and improving real-world systems — from startups to large-scale products.

I focus on test automation, reverse engineering, and application security. I care less about raw theory and more about what actually works in practice.

🎯 What I Do

  • 🧪 Build and maintain automation frameworks (Java + Selenium / Selenide, Playwright)
  • 🔍 Perform deep testing — from UI flows to network-level and backend validation
  • 🛠️ Analyze and modify apps using Frida, Objection, and reverse engineering tools
  • 🔒 Explore application security and bypass techniques (root / detection / instrumentation)
  • ⚙️ Integrate testing into CI/CD pipelines (Maven, GitHub Actions)

🔧 Tech Stack

Testing

  • Selenium / Selenide (Java)
  • Appium
  • Test design, regression strategy, CI integration
  • UI + API + network-level validation

Security & Reverse Engineering

  • Frida, Objection

  • Traffic interception (Charles Proxy, Wireshark)

Development

  • Java (primary)

🚀 Current Focus
