This should be quick and easy as I have worked on dozens of freelance web development projects on other freelancing platforms such as Upwork and PeoplePerHour. Recently, I worked with a Japanese client on Upwork regarding a very large web page layout. There was a lot of content that needed to be displayed and we both agreed that the deadline should be 2 days. I managed to write almost 300 lines of HTML code and more than 400 lines of CSS codes in less than one day, more specifically, around 11 hours of non-stop work time. I even recommended the client to add JavaScript animations to the web page, in which the client agreed and resulted in the website looking much more beautiful. The page is now fully responsive both mobile and desktop. The client was then very much satisfied with my work (see my recent review on Upwork). See my portfolio on a Japanese HTML/CSS Markup.
I have 3 LinkedIn Skill Badges in PHP, CSS, and HTML, which puts me at the top end of all full-stack web developers globally. In addition, I have my own JavaScript animation framework that enables me to develop animations pretty quickly.
With my vast web development experience, I am very confident that I can complete the project much faster than other freelancers, fully responsive to both mobile and desktop. Regarding the budget, I would be very satisfied with a $30 budget, considering the living costs in Indonesia aren't all too high.
