Work Experience
AWS Senior Developer
Leadstorm LLC
- Created an application using AWS Lambda and API Gateway to pull data from GoHighLevel API and store it to AWS S3 to satisfy compliance rules.
- Wrote CI/CD code for deployment to AWS using AWS CDK (Python 3). The CI/CD process is flexible enough to deploy to different accounts (prod) or the same account (dev).
- Found a crucial workaround to overcome poor GoHighLevel API capabilities. Used Mailgun API instead.
