I developed an automation framework for over 40 microservices and 1,000 endpoints.

This framework allowed us to write integration tests without any business knowledge. It held all of the required information about business entities. It supported eight development teams that developed the API solution.

Framework Work Benefits:
• Focus on testing specific areas instead of worrying about all dependencies.
• Easy creation of the whole required configuration for any business scenario.
• Handle all possible situations that API could return such as all errors, versioning, and automatic retries.
• Provide logged data for metrics which made it easier to solve problems.

We needed a way to schedule executing of tasks and events at specific second on remote devices. This led me to create a serverless architecture with three microservices.

One is responsible for configuration and device information, the second for creating specific tasks/events for devices, and the third for scheduling (specific dates, times, events) and task executing.

Currently, it is working fine in production with real clients.

Technologies: Ruby 2.7, AWS DynamoDB (for constant read times of events to execute), AWS Lambda (for all workers), AWS API Gateway (for the API to connect to Lambda), AWS SQS (for passing data between workers where needed)
