Summary: I need a backend system developed. The domain modeling is done and I've written some code to perform CRUD of some models (5 to 6 models) as well as the api for my frontend to consume. I need someone to complete the CRUD of the models and develop new features and api. New features and API: - Search suggestions/autocomplete (will share more info on this) with optimization, i.e. it should be fast - Store and display top k most searched queries - User signup/login(can be via Facebook or Google login or email+password) and registration verification for email signup(send email with a link for user to click to verify their email). - Authentication module. Access control to services. - API and services to optimise and upload images to AWS S3. Stores the S3 link in db. Images to be optimized for mobile and web usage. U need to know the optimal compression, image sizes and etc. - Services to call Google Places and Translate API. - A service to find the lat and lng coordinates of an address - Services to support batch upload of the model data (includes images, which need to be stored in S3) Others: - Code refactoring/clean-up if needed. - Tests for the services and apis Remarks: I have different frontend systems accessing the backend services. I want my backend services as microservices with an API gateway exposed for the frontend to access the backend services. I will discuss and share detailed info with the shortlisted developer/team. Tech: Nodejs, ExpressJs, Mongodb. AWS S3, Cloudfront, EC2. Open to using other tech if necessary. What I look for: Developer/team who are expert in the above, able to architect and able to advice the best solution for my needs. Should have experience in AWS as well. *I'm not looking for part-time freelancers. Bidding: Please provide relevant experience and projects in your proposal and give a good estimate of how much you will charge. After I have shared with you the project in detail, u can amend your bid according. Pls write the text "Full-time" at the top of your proposal to be considered. For the successful bidder, I will create mini milestones/project for him/her/them to work on.
