TypeScript Expertise

TypeScript is central to Max Fritzhand's engineering practice. He uses TypeScript across frontend, backend, and tooling codebases to enforce type safety, improve developer experience, and reduce runtime errors. From building complex SaaS frontends at Bolta to designing automated test suites at EXPANSIA with Playwright, TypeScript provides the foundation for reliable, maintainable code across all his projects.

The Practitioner Angle

In production, TypeScript isn't just about syntax — it's about predictable outcomes. Most teams struggle with TypeScript when systems scale beyond a single engineer. I focus on building sustainable patterns that lead organizations.

Typical Engagement: Solving scalability & flakiness

Experience Highlights

Implemented TypeScript across Bolta's entire codebase spanning frontend, API routes, and automation logic

Designed CI/CD workflows and 120+ automated test suites using TypeScript and Playwright at EXPANSIA

Built type-safe data models and API interfaces for complex B2B applications at HandyApp

Used TypeScript for design system tokens and component APIs at NGA, adopted across 12 internal apps

Frequently Asked Questions

How does Max Fritzhand use TypeScript in production?
Max uses TypeScript as the default language across all his projects. At EXPANSIA, he converted 120+ manual tests into TypeScript-based automated suites. At Bolta, the entire stack — React components, Next.js API routes, and business logic — is written in TypeScript with strict mode enabled.
What is Max Fritzhand's approach to TypeScript type safety?
Max favors strict typing with no 'any' escapes, leveraging discriminated unions, generics, and Zod for runtime validation. He designs type-safe APIs that catch errors at compile time and uses TypeScript's inference system to minimize boilerplate while maximizing safety.
Does Max Fritzhand write backend TypeScript?
Yes. Max writes full-stack TypeScript including Next.js API routes, Node.js services, and serverless functions. His TypeScript backend work includes REST API design, database query typing, middleware chains, and integration with third-party APIs.
