About the service
I develop reliable backends and tools on Haskell for teams that value correctness over shipping quickly and hoping it doesn't break in production. I always start with the type system: I model the domain so that invalid states simply can't be expressed, and the compiler cuts off entire classes of errors before the first test runs. Pure functional design pushes side effects to system boundaries, so the core logic stays simple to reason about, convenient to test, and safe to refactor months later — without fear of hidden regressions.
Over the years, I've written calculation engines for finance, compilers and interpreters, parsers for tricky formats, and long-lived critical services where a wrong answer costs real money. Haskell fits these tasks perfectly: exhaustive case analysis, referential transparency, property-based testing via QuickCheck, and strict static guarantees mean the program behaves the same on the first run and the thousandth. I carefully profile, control laziness where it matters, and keep code readable, not clever.
Reach out when you need a system that's genuinely hard to break. I deliver clean documented modules, a test suite that captures exactly the behavior you rely on, and honest advice on where Haskell helps and where another tool might be simpler.
— API design and domain modeling through types
— Compilers, parsers, DSLs, and interpreters
— Finance and correctness-critical backend services
— Property-based testing, profiling, and refactoring existing code
