As a highly qualified full-stack developer with extensive experience in web design and development, I have a deep understanding of what it takes to create a successful video-based website with chat functionality. My team and I have successfully completed similar projects for over 150 companies which have honed our skills to perfection. We are proficient in all the key tools and languages necessary such as - HTML, HTML5, CSS & JavaScript, Bootstrap, PHP, Java, Python and many more.
Moreover, our expertise stretches across creating native and cross-platform mobile applications in Flutter, which will be a valuable asset in ensuring your website's compatibility with multiple operating systems. We are well-versed in database management systems like MySQL and SQL that will serve your site's needs efficiently.
However, since you specified your budget is not more than $20 for this project, we would humbly request reconsideration as this is significantly lower than current market rates for such complex work. We guarantee top-quality delivery on time with extended support – values that decide the success of any project. Given an appropriate budget and milestones, let's bring your envisioned chat-integrated video website to life with efficiency and excellence.
