How large is the website you are developing?The technology used will vary depending on the scale of website development. For example, for small- to medium-scale development, Wordpress and Ruby on Rails are the preferred backend technologies. This is because development speed is fast and development costs can be kept down. For large-scale development, Laravel, .Net, etc. are often used. This is because it is highly secure and highly scalable.
Are there many libraries?Libraries differ depending on the programming technology, but we will select the technology according to your company's development requirements.
