‘Hire dedicated developer’ means a developer or designer working as your own employee, but sitting at our office. It’s a huge cost saving. It reduces many costs to you such as recruitment cost, employee benefits, infrastructure costs, etc., and still, the resource works exclusively on your projects alone.
If you are a design agency or development agency that has loads of work and do not want to hire an in-house developer or to just outsource, engaging a dedicated developer is your best option. You would not have overheads and would still retain control over the development activities.
