ATLAS

Atlas is building the operating system for restaurants. Atlas is the easiest way to start, run and grow any restaurant online and offline. We are the team that previously built Grain, a venture-backed online restaurant, to millions in revenue. Team and investors are from Grain, Accenture, Microsoft, Udacity, McKinsey, Salesforce, Y Combinator and others. https://atlas.kitchen

Languages: Ruby, Javascript Frameworks (frontend): React, React Native, Tailwind CSS, GraphQL Frameworks (backend): Ruby on Rails, Node.js, GraphQL DevOps: Google Cloud Platform, CloudRun, Docker, Terraform, Cloudflare Workers, Firebase, Craco Storage: PostgreSQL (CloudSQL), Workers KV Payments: Adyen, Stripe

Technologies we are experimenting with:

• Cloudflare Durable Objects for real-time applications.
• Migrating our app to Vite for faster build times.
• Micro-mono repo to scale out different services using the same application.

Our application is a multi-tenant SaaS product with support for isolated databases and compute instances, meaning each tenant gets a dedicated database (isolated data) and dedicated compute (highly scalable) to process requests. We built a custom API router (like DNS) to redirect requests to the right destinations.

We primarily write code in Ruby and use Rails for our backend framework and we use React (with Ant design + Tailwind CSS) for the frontend applications. We run our Rails applications on Cloud Run and serve our frontend applications using a mix of Firebase and Cloudfare Workers, they communicate primarily through GraphQL. Our custom API router is built on Cloudflare Workers and KV store for high availability and performance. We use managed Postgres (Cloud SQL) and Workers KV to store application data.
