Koredl

An ML interview-prep platform with hands-on practice inside your own code editor.

TypeScript · VS Code Extension API · Django · PostgreSQL · Temporal · React

Koredl is an ML interview-prep platform I built with a small team. People trying to break into machine learning roles are stuck between university courses that teach theory disconnected from what interviews actually test, and coding-interview platforms like LeetCode that have no real equivalent for ML practice. Koredl combines the structure of a learning platform with hands-on, industry-aligned ML problems, delivered through VS Code and Zed extensions so learners train and test models in their own local environment. The platform runs on a Django and PostgreSQL backend with Temporal for background workflows, plus a React and TypeScript web app. My focus has been on development, particularly the code-editor extension. Koredl is now live and in beta.
