Front End Developer React to fix bugs on Booking Platform
It was a pleasure working with Serhii. He quickly understood the existing React and Next.js codebase, fixed the bugs, and improved the overall quality of the application. The issues were fixed with good attention to detail, the new components matched the Figma designs and responsive layouts worked well.
Communication was very good. He replied quickly, made changes fast and delivered everything on time. All requested tasks were completed as expected. I would be happy to work with Serhii again on future React and Next.js projects.
