Optimize my website + Small changes as required in frontend

Job ID: 35575791

Budget: $30 – $250 USD

I have a website built with Next js (bootstrap for css) and Node js. It's a dynamic website. I want to optimize the code (make the website/loading time faster) preferrably using React Query or any other technology that you find optimal, and implement a couple of small changes in front end as needed.
