$25-50 USD / hour

We are building a gaming platform and are looking for someone who can help develop our match API according to an existing API spec. The API should leverage AWS Amplify or the technologies it depends on. You should be experienced with AWS technologies such a: • Amplify • App Sync • GraphQL • Cognito • Lambda • DynamoDB Required technologies & example usage: AppSync GraphQL API To be called from website and mobile clients. We want to use dynamodb as our backend datastore and Lambda functions may be necessary. Some endpoints will need to be authenticated and some will need to be public. We want to use Cognito for user management and endpoint authentication. We have two primary models. Users and Matches. Users can have many matches. Every match has two users. We may need a relationship model to hold edge data. Cognito User Pools We want to leverage Cognito to manage our users accounts, however, we will also need to store additional platform data for our users. We do not want to store platform user data in cognito itself. We will need to synchronize our users between cognito and dynamodb. Lambda Functions We want to have a serverless infrastructure which uses AWS Lambda functions to implement the core business logic. Examples: • Each user will have data for a match ( edge data ) • Users will need to be able to create matches • Users will need to be able to join matches • Clients will need to be able to check the status of a match • Clients will need to be able to submit data for a match Please reply if you have experience with the above and your rate and we will reach out to you on next steps if we feel you would be a good fit for the project. We look forward to meeting you!

Dear client Pierce. I hope you are doing great. I have read your post carefully and I can see that you need to build the API according to an existing API spec for the gaming platform. I think you want to use AWS as the backend on your website. I have to build using AWS amplify GraphQL backend and React styled component frontend. I have so deep knowledge of AWS amplify + React development. I have experience developing the event website using amplify and React(Angular & Vue). Front-End development using a special framework needs its all concepts, so I know almost all modern concepts and hooks in React.js from the experience of many years. I have mastered Cognito User Pool, DynamoDB and Datastore, S3 Storage, GraphQL schema design, CodeCommit, and Lambda function offered in AWS and React/Redux/Redux-firebase/Saga/Styled component/Gatsby/Material UI, etc. Also, I have deep experienced in Git including pull requesting and repository management, so that you can check work progress anytime when you want. I will finish this project asap for you and me. I want to discuss your project in more detail. I wish to succeed in your website. Regards, Maksim
