<p><a href="https://fulcrum.lever.co/the-lever-tech-stack-1b30e27d2bb0">Blog Post on our Tech Stack</a></p> <p>Lever uses our own open source MVC framework called Derby that syncs all data via Operational Transformation (the algorithm behind Google Docs). OT is the way we handle concurrency conflicts for any piece of data that is edited at the same time. In addition to real-time sync, OT allows us to provide a smoother UI since we can render updates on the client instantly without waiting for our backend to respond, while still guaranteeing consistency.</p> <p>Lever makes extensive use of AWS, Docker, Node, Mongo, ElasticSearch, and Redis within our infrastructure. We use tools like Hubot to streamline deployments and Grafana to see what’s going on under the hood. In addition to automating all the things, we love to version them too! Our systems are all created using Terraform and Chef, working together to ensure consistency at all costs.</p>

<p>We have a service oriented stack deployed on AWS using containers. Most of our backend services are written in Go, with the exception of an NLP/ML service written in Python. Services talk to each other using gRPC.<p> <br> <p>Our web application is served statically from Cloudfront/S3 and is written using React. Is is a Progressive Web App, with a service worker to speed up delivery.</p> <br> <p>We integrate with third party software such as Google Drive, Calendar, Jira, GitHub, Asana, Slack. These areas are some of the most complex parts of our systems. They’re also some of the most important: integrations enable the “magic” of a user coming to Range in the morning and seeing all of their work from the previous day already gathered in one place.</p>

<p>We use Apache Spark, AWS EMR, AWS Data Pipeline, AWS Lambda, AWS CloudFormation, Google Firebase, GCP cloud functions on the infrastructure side. On the language side, we use Scala for machine learning, Golang, Python and Node for data pipelines, and React and Javascript for frontend.</p> <br> <p>We have a modern stack built on per-customer, structured data lakes augmented with declarative schemas that describe what the data represents and how to transform it into features useful for machine learning.</p>

GitHub is a Rails 4 application that is composed of a large monolith and a constellation of services written in Ruby, Go, and a handful of other languages. The app and its services are exposed both internally and externally via a GraphQL API. We primarily rely on MySQL for persistent storage, Redis for temporary storage, and, as you might expect, a lot of git repositories. We rely on Kubernetes for container orchestration.
