Backend Development Jobs

Backend code is the part of a website or application that isn’t visible to the user. The code is a behind-the-scenes part of development, requiring a high level of competency regarding coding and the server that is being used. A backend developer works on the implementation and configuration of systems, and thus provides the building blogs for a website or program.

    I need an adult escort services website done. I want something that would be 70% like website done on WordPress or so. So that the admin can easily managr the page and content.

Subscriptions: Models and clients can move from free users to subscribed accounts which gives extra features but will have to pay like $10 per month. This will only be for 1 country but will have filter locations for the different parts of the country. Clients and escorts should be able to create profiles.

    I'm using cargo collective to build my new site. They have a "backdrop" option on their individual post design options that allows you to choose a background video by pasting a youtube/vimeo etc link. I want to use this option but it doesn't allow you to show the controls (play,vol etc). I need someone who can look at the backend and change the script so everything is the same but the videos show the controls and you can click them when visiting the page. You can see a very basic version of the layout here - I've attached images of the actuall layout and the backend so you get an idea of what it is. Thanks

    Cloud Infrastructure Currently, we are pursuing a microservices architecture based on Google's Cloud Platform (GCP) consisting of roughly 6 - 7 services all exposed via a GraphQL mesh and IAM authentication. Having said that, we want you to bring your ideas and experience to the table too to help us make these decisions. Live Data Feeds The app relies on the consumption of multiple live data feeds from multiple different sources. (Some of these feeds will be within the minute refresh cycle while others might be daily). These feeds need to be collated, organized and then provided in an accessible structure via external interfaces. All of this needs to be done in a cost-effective way so as not to incur large costs for compute. Robust feed collection will be via REST API and XML...
