OCaml Web Backend (OCaml, Docker) overview

A web backend written in OCaml, leveraging the language's powerful type inference and pattern matching to build correct-by-construction HTTP handlers. OCaml's algebraic data types and exhaustive pattern matching catch entire classes of bugs at compile time that would be runtime errors in most other languages. PostgreSQL handles persistence through OCaml's strong FFI ecosystem. Docker packages the native binary into a minimal Alpine container, yielding tiny images with fast startup. The tradeoff is a smaller ecosystem compared to mainstream languages, requiring more hand-rolled infrastructure code, but the result is exceptionally fast, memory-efficient services with strong correctness guarantees.
