Technology

Python

Python is the most popular programming language in the world, optimized for developer productivity. Great for web development and the de facto standard for AI/ML applications.

Django

Django — no. 1 web framework for Python. It combines rapid development with the ability to scale and powers many well-known services, such as Instagram, Spotify, The Washington Post, Bitbucket, Sentry, etc.

Celery

Celery is our go-to framework for running tasks in the background. It’s mature, robust, and integrates well with Django.

Docker

Docker is the industry’s standard containerization tool. It powers all our projects, managed with Kubernetes or ECS in production and Docker Compose in development.

React

React is the most popular frontend framework. It’s fast, robust, and very practical. We can build almost anything with it, thanks to its huge ecosystem and vast developer community.

MUI

MUI is one of the most advanced and well-maintained frontend component frameworks. Plays well with React.

React Native

React Native is a multi-platform framework for native app development based on React's concepts. It works well for many business applications and allows engineering teams to stay lean and flexible, switching between web and mobile development when necessary.

GraphQL

GraphQL significantly boosts frontend and mobile development productivity. It could be more challenging on the backend, but in our experience, it’s a reasonable tradeoff.

REST

REST is a classic approach to building APIs, which still has its place in modern web development.

Amazon Web Services

AWS is our favorite cloud. Based on our experience, AWS provides the best combination of functionality, stability, and customer support.

CloudFormation

Terraform

CloudFormation and Terraform are tools for defining infrastructure as code (IaC). CloudFormation only works with AWS, while Terraform is multi-cloud. Both of them are great, and we use both.

pytest

Jest

We use pytest for writing automated tests in Python and Jest for JavaScript / TypeScript. Both frameworks are powerful, convenient, and provide a robust foundation for building a test suite for the backend and frontend.

Playwright

Playwright makes writing end-to-end tests a breeze. For years, developers struggled with flaky end-to-end tests written in Selenium and similar frameworks. Playwright significantly improves the developer experience and provides great debugging capabilities, boosting overall development performance.

Sentry

Sentry is our favorite crash-reporting tool, which seamlessly integrates with our Python and JavaScript apps, allowing us to catch bugs early.

AWS CloudWatch

AWS CloudWatch helps us keep an eye on our infrastructure in AWS.

New Relic

Datadog

New Relic and Datadog are the two leading providers in application performance monitoring (APM). Both are great, and we use both.

Uptime.com

Pingdom

We use Uptime.com and Pingdom for service uptime monitoring.
