What I'm looking for

I’m looking to grow further as a Java and backend-oriented Software Developer, building reliable, well-structured software systems.

At Arringo, I built a TypeScript and Python automation framework from scratch for a FinTech platform, covering transaction flows, CRM operations, and reports. I validated backend data with SQL and integrated automated checks into CI/CD pipelines.

At Grid Dynamics, I designed automation frameworks for mobile e-commerce and web AdTech projects, using Java with Appium and TypeScript with Playwright. Earlier, I worked as a Software Engineer with C# and MS SQL; I’m now focused on growing as a Java and backend-oriented Software Developer while pursuing a PhD in Computer Science at Kharkiv Aviation Institute.
