FAQ
Q1: Will converting my code to TypeScript break my app?
A: Not at all! TypeScript compiles down to standard JavaScript. I test and verify that your application's logic, endpoints, and components work exactly as expected before delivering.
Q2: Do you just use 'any' types to bypass errors quickly?
A: Absolutely not. I write explicit interfaces, type aliases, and generics so you get the full benefits of TypeScript's compile-time safety and IDE auto-completion.
Q3: What do I need to provide before starting?
A: Just a brief overview of what your app does, access to the repository (or a ZIP file of the source code), and details on your build setup (like Vite, Next.js, Node, etc.).
