PureScript Developer — Strongly-Typed Functional Frontends
Service description
I am a PureScript developer, and I build strongly-typed functional frontends that compile down to clean, dependable JavaScript. If you want a web application where whole classes of runtime errors simply cannot happen, PureScript is my tool of choice. Its Haskell-inspired type system, algebraic data types, and total-function discipline let me model your domain precisely, so the compiler catches mistakes long before a user ever does. This is not Elm and it is not TypeScript with a few generics bolted on — it is a genuinely pure functional language with row polymorphism, type classes, and effects tracked in the types, and I use every bit of that expressiveness to keep your codebase honest.
In practice I architect applications around a clear, pure core with side effects pushed to the edges. I work comfortably with Halogen for component-driven UIs, with React-style bindings when a project needs interop, and with the wider PureScript ecosystem for routing, forms, HTTP, and state. Because the type system enforces the contracts, refactoring stays safe even as the application grows: I can rename, restructure, and extend features knowing the compiler will flag anything I broke. The result is a frontend that behaves the same way every time, is a pleasure to reason about, and hands the next developer a codebase that documents itself.
Whether you are starting a greenfield app, adding a typed island inside an existing JavaScript project, or rescuing a fragile UI that keeps surprising you in production, I can help. I write readable code, keep the FFI boundary small and well-documented, and pair the work with tests and a clean build pipeline so the whole thing stays maintainable long after I hand it over.
— Strongly-typed PureScript frontends compiled to JavaScript
— Halogen component apps and React-style interop
— Pure functional architecture with effects at the edges
— Domain modelling with ADTs, type classes, row types
— FFI bindings to existing JS libraries and APIs
— Routing, forms, HTTP clients, and app state
— Build setup, tests, and safe refactoring
