TypeScript

A strongly typed programming language that builds on JavaScript, giving you better tooling at any scale.

TypeScript is a superset of JavaScript that adds static type definitions, enhancing code quality, maintainability and developer productivity.

It provides compile-time error checking, improved IDE support with autocompletion, and better documentation through explicit type declarations.

Experience:

Implemented TypeScript across projects including LegalAgent, Opyn, and BitLauncher for type safety and maintainability.

Applied TypeScript for RAG architecture in LegalAgent and EVM contract interactions in Opyn and BitLauncher.
