I run a SaaS page builder that generates amp websites for my customers. It's targeted towards small agencies that currently rely on wordpress.

--

Backend: Node.js hosted on AWS ECS (Docker) and Lambda Frontend: JavaScript, React Database: Postgres (AWS RDS; thinking about switching to serverless aurora)

As for delivering my clients sites I recently switched from cloudfront to stackpath (DNS, CDN) because the pricing model makes more sense for me and it doesn't have arbitrary limitations like the distribution limit.

Other tech I use:

- Terraform for my whole infrastructure

- AWS SES for sending mails

- AWS Cognito for authentication and managing user accounts

- AWS Cloudfront combined with lambda@edge for delivering images in the right size for the requester (src-set)

- Github

- AWS CodePipeline for CI and deployments (source input through github releases)
