Technologies: AWS Lambda, DynamoDB, S3, REST API, POSTMANContributing to the design and implementation of a backend system using AWS's serverless offerings. Learning and applying best practices in a real-world setting, resulting in a scalable and efficient solution.Key Learnings & Contributions:Serverless Backend with AWS Lambda:Assisted in deploying Lambda functions for various business logic components.Gained hands-on experience with error handling, logging, and monitoring in AWS.Data Storage with DynamoDB:Collaborated in designing a NoSQL database structure in DynamoDB.Learned the intricacies of optimizing data retrieval using primary and secondary indexes.File Storage and Management with AWS S3:Worked alongside the team to integrate AWS S3 for storage and retrieval of essential assets.Familiarized myself with S3 policies and access controls to ensure data security.RESTful API Development:Contributed to the development of a RESTful API for frontend communication.Grasped the importance of API versioning and backward compatibility.Flow of Backend Operations (Contributed to understanding and documentation):1. API Gateway receives the API request.2. Lambda function is triggered based on the specified endpoint.3. Lambda interacts with DynamoDB for data operations or S3 for file tasks.4. Computations and manipulations occur within the Lambda environment.5. The client receives a response via API Gateway.
