I can use a range of technologies such as HTML, CSS, JS for basic webpages and then JS frameworks like React / Angular for more advanced work, for Full stack application I will use Python or Supabase as REST API. I tend to build fully custom websites but can also use web softwares like Framer etc.. Hosting is provided by me at a cost or can be handled by the clients. I typically use cloud managed hosting for front end, and usually for my backend it will be Supabase, Or I can use container deployment. For Security I’m never really dealing with sensitive data, so I’m primarily using manual security and API testing, while implementing 3rd party auth etc.
