Create AWS lambda function

Description

Need an automated cloud workflow that runs on a schedule or when files are uploaded to Amazon S3?
I will create and deploy a fully functional AWS Lambda function that automatically executes tasks such as database updates, API calls, file processing, or data synchronization — triggered either by S3 bucket events or an AWS EventBridge (CloudWatch) scheduler.

This setup eliminates manual effort and ensures your workflow runs automatically, securely, and reliably — all within a single day.

What You’ll Get

✅ Custom AWS Lambda function (Python or Node.js)
✅ Integration with either:

S3 Bucket Trigger: Runs automatically when a new file (e.g. CSV, JSON, image) is uploaded.

AWS EventBridge Scheduler: Executes your function daily, weekly, or at any specified time.

✅ Secure environment variable configuration for credentials (DB, API keys, etc.)
✅ Logging and monitoring via CloudWatch Logs
✅ Optional: File parsing, database updates (MySQL, DynamoDB), or API integration
✅ Step-by-step documentation so you can manage or modify the setup yourself

How I’ll Complete It in 1 Day

Phase 1 — Setup (2 hours):

Configure AWS IAM roles, permissions, and Lambda execution policy

Create the Lambda function and configure triggers (S3 or scheduler)

Phase 2 — Development (3–4 hours):

Write and test the Lambda code (e.g., read file from S3, update database, call API, or process data)

Add logging, error handling, and environment variables

Phase 3 — Testing & Deployment (1–2 hours):

Run end-to-end testing using sample data

Validate CloudWatch logs and S3 or schedule trigger

Deliver documentation and final demo
