IoT & Serverless Backend

AWS Mobile & IoT Store Information Platform

An AWS serverless backend serving an Android mobile app and connected IoT machines. Amazon API Gateway routes requests to User and Store Information Lambda functions, secured by Amazon Cognito and Active Directory, with Amazon DynamoDB storage, IAM roles, CloudWatch logging, and S3-hosted configuration.

01 Overview

An AWS serverless backend serving an Android mobile app and connected IoT machines. Amazon API Gateway routes requests to User and Store Information Lambda functions, secured by Amazon Cognito and Active Directory, with Amazon DynamoDB storage, IAM roles, CloudWatch logging, and S3-hosted configuration.

Scope of delivery

Built an AWS serverless architecture where API Gateway exposes User Service and Store Information Lambda functions for the Android and IoT clients, with Cognito + Active Directory authentication, DynamoDB persistence, IAM roles, CloudWatch logging and S3 configuration storage.

02 Business Challenge

Deliver a scalable cloud backend for an Android app and connected IoT machines, with secure user and store-information APIs, identity access control, and operational observability on AWS.

03 Our Solution

Built an AWS serverless architecture where API Gateway exposes User Service and Store Information Lambda functions for the Android and IoT clients, with Cognito + Active Directory authentication, DynamoDB persistence, IAM roles, CloudWatch logging and S3 configuration storage.

Engineering approach

Designed and deployed a serverless backend on AWS - API Gateway to Lambda services for users and store information, fronted by Cognito/Active Directory identity and protected by IAM roles, with DynamoDB storage, CloudWatch observability and S3-hosted configs.
