Desired Candidate Profile

Our tech stack: TypeScript, MobX, Hasura, PostgreSQL, Python, Apollo, GraphQL, SQL, Flask, Redis, RQ, JavaScript, React, Vim, VSCode, HTML, CSS and AWS. Our flagship product uses image recognition to identify elements in construction PDFs, built with Python (numpy), Postgres and React. For newer real-time collaborative features, Hasura gives us a GraphQL subscription layer over Postgres, which is transformed into MobX objects on the frontend.
