Expert TypeScript Consulting Services
Type-Safe JavaScript at Any Scale
TypeScript is the superset of JavaScript that adds static types and tooling, used by 80%+ of professional teams. Our TypeScript consulting helps codebases become safer, faster, and easier to maintain.
What Is TypeScript and Why Do You Need a Consultant?
TypeScript catches bugs at compile time, powers world-class IDE tooling, and makes large codebases tractable for big teams. Total Shift Left helps organizations migrate JavaScript projects to TypeScript incrementally, design strong type architectures (generics, conditional types, branded types), enforce strict mode, set up shared type packages in monorepos, and integrate TypeScript with React, Node.js, and serverless stacks.
At Total Shift Left, our TypeScript consultants bring deep, hands-on experience from dozens of enterprise implementations. Whether you are evaluating TypeScript for the first time, migrating from another platform, or looking to optimize your existing TypeScript setup, our team provides the expertise you need to succeed. We serve as your trusted TypeScript consulting partner — from initial assessment through implementation, training, and ongoing support.
