Hey there, I'll be able to help you configure your Matrix Synapse server & your Element Web client on your VPS. I have over 7 years of experience with Linux systems administration, performing tasks like configuring websites such as static Hugo websites (including my own), Laravel websites, WordPress websites, but also configuring DNS, SSL certificates, and webservers, alongside cPanel & Softaculous installations. I have done this kind of work for clients in the past and I'll be sure not to let you down. Alongside that, I do have experience with full stack web development and software development, utilising technologies like PHP with Laravel, JavaScript, TypeScript with Angular, Python, Golang, Docker, MySQL and a whole host of others.
As always, if you do have any questions, please do let me know :)
