Good day!
I can improve your website. I am personally certified php developer with 15+ years of experience. I have a good knowledge in technologies requested in your project.
In area of web development my main specialization is LAMP stack of technologies (Linux, Apache, MySQL, PHP) but I have experience with Python, Node.js and .NET stack of technologies either.
If you are interested, please, send me a message in a chat that we could discuss the details.
