Can build high‑quality REST APIs (we use Python for APIs, but experience building APIs in TypeScript, Go, etc. is also OK). Are proficient with relational databases and application‑style SQL. Plenty of experience using an application database stack like ActiveRecord with Rails, Python SQLAlchemy, TypeScript Drizzle, etc. Ability to write SQL by hand if needed, including joins and aggregations.
