Experienced QA Engineer delivering scalable solutions across various sectors.
What I'm looking for
With over 9 years of experience in quality assurance and more than 12 years in IT, I have a proven track record of delivering scalable QA solutions across Web3, e-commerce, and finance sectors. My expertise lies in manual, automated, performance, and security testing. I have successfully built QA departments from scratch, establishing robust quality processes and frameworks that align with business goals.
In my recent role as a QA Engineer at Moralis, I designed and maintained both manual and automated test frameworks for web-based platforms. I drove performance testing using K6 to ensure protocol stability and reliability, while also mentoring QA engineers and providing technical leadership. My collaborative approach has allowed me to work closely with DevOps, developers, and product teams, fostering a culture of quality and continuous improvement.
Throughout my career, I have been committed to quality, agility, and enhancing processes. I thrive in fast-paced startup environments and am always eager to take on new challenges. My technical skills include a diverse tech stack, and I am dedicated to promoting cross-team collaboration to achieve exceptional results.
