Lightning — ER Diagram Editor

Higher School of Economics04/2022

Rough prototype — the zero-code ambition outran the execution.

No commercial outcome, but it crystallized a lasting interest in low-code tooling and, later, AI-assisted development as ways to close the gap between an idea and a working service.

Draw a table, get the SQL

Edit the entity the way you would on the Lightning canvas — the CREATE TABLE statement rewrites itself as you type.

Generated SQL

CREATE TABLE articles (
  id INTEGER PRIMARY KEY,
  title VARCHAR(255) NOT NULL,
  published_at TIMESTAMP
);

This live table-to-SQL step was the part of the zero-code idea that actually worked. Relation SQL and mock data stayed stubs; the request-tree panel exported a real Postman collection.
