I specialize in Infrastructure, Backend, and Web automation, with expert-level experience in architecting custom testing frameworks from the ground up using:
- Playwright and Selenium for web automation;
- pytest for backend and API services;
- Foundry and Hardhat for smart contract and blockchain integration testing;
- REST/GraphQL tools for backend verification.
I am highly proficient in orchestrating these suites within CI/CD solutions, utilizing Docker for containerization and Linux for infrastructure management. Beyond technical execution, I have extensive experience in mentoring engineering teams and defining quality strategies that integrate seamlessly into the SDLC. I bring a deep understanding of the testing lifecycle, ensuring that reliability and security are core components of every project from conception to deployment.
