Serverless technologies enable developers to focus on creating user value while leveraging cloud services for scaling and security. As a solo engineer, I've been able to accomplish tasks that previously required a team of engineers, achieving similar results in significantly less time and cost. However, with great power comes great responsibility, as we must understand and work with various services, configuring them correctly and using them efficiently. To overcome these challenges, I rely on seven essential tools: Serverless IDE for auto-completion and schema validation, IAM Legend for secure IAM policy writing, Dynobase for intuitive DynamoDB management, evb-cli for EventBridge workflow automation, the Mapping Tool for VTL template building and debugging, org-formation for infrastructure-as-code AWS organization management, and Lumigo for issue detection and troubleshooting. These tools have significantly improved my productivity and effectiveness as a serverless developer.
