   Architecture & Design Responsibilities • Design scalable, fault-tolerant AWS solutions using a serverless architecture pattern involving AWS Lambda, API Gateway, and DynamoDB. • Architect end-to-end RESTful APIs using FastAPI, integrated with AWS services through API Gateway and Lambda. • Ensure database models in DynamoDB are optimized for performance, scalability, and cost-efficiency, including partition key design and access patterns. • Implement secure, scalable, and low-latency APIs for internal and external consumers using API Gateway features like throttling, usage plans, and custom authorizers. Application Development & Deployment • Build, test, and package FastAPI-based Python applications that are containerized or zipped for Lambda deployment. • Use GitHub Actions to automate CI/CD pipelines for both application and infrastructure code: • Linting, testing (Pytest/Unittest) • Building and packaging Python FastAPI applications • Deployment to Lambda and updating API Gateway stages • 🧪 Implement robust unit and integration test strategies for FastAPI and Lambda functions. Infrastructure Provisioning using Terraform • Write reusable, modular, and version-controlled Terraform modules to provision: • Lambda functions • API Gateway REST APIs • DynamoDB tables with autoscaling and TTL • IAM roles and policies for least-privilege access • CloudWatch logs and metrics for observability • Use Terraform Workspaces or Terraform Cloud to manage environments (dev/stage/prod). • Integrate state locking and versioning using remote backends (e.g, S3 + DynamoDB). • Implement secure secrets and environment variable handling using SSM Parameter Store or Secrets Manager via Terraform. Security, Monitoring & Optimization • Apply least privilege IAM policies for Lambda, API Gateway, and DynamoDB access. • Enable WAF (Web Application Firewall) and throttling policies on API Gateway.
