• More than 15 years of experience in product development, startups, and outsourcing, including 5 years in lead and engineering management positions.
• 12 years as a QE, AQE, SDET, and QE Lead, and 8 years of development experience.
• I also have experience in DevOps and Site Reliability.
• Have experience using GPT API to solve business needs.
At the moment, the technology stacks I am utilizing include:
• Ruby + Rails back-end
• Java combined with Dropwizard framework
I am capable of resolving front-end issues, but my primary expertise lies in business and back-end development tasks as I do not have any experience with modern JS frameworks.
• Design and implementation of high performance and scalable solutions (took a major role in re-designed of the data intensive workflow that operates with large volume of events).
