🟢 4+ years in building large and medium Nextjs apps 🟢 6+ years in React based apps I have over six years of experience building frontend applications based mostly on React stack. Last 4 years I've been working on big applications based on NextJs, so I have some experience on that. I can also help you with anything related to frontend ecosystem: testing, e2e, ci/cd, cloud, etc. If your NextJs app goes slow or you need help with memory leaks hunting, feel free to contact me also. Generally, I'm full-time employed person, but I'm always like to help other people with different projects to expand my knowledge. I have flexible working hours and usually have around 8hr per week to work on something else besides my main job. Thank you.
