Dafny is a programming language and verification tool designed to support formal reasoning about program correctness. It includes features for writing specifications, implementing programs, and formally proving that implementations meet their specifications through automated theorem proving.

A Dafny expert must have strong skills in formal logic, automated theorem proving, and program specification. Proficiency in writing and understanding preconditions, postconditions, invariants, and lemmas is essential. Familiarity with the Dafny language syntax and its integrated development environment (IDE) is also crucial.

How to hire a Dafny expert

Dafny was created in 2009 by Microsoft Research to facilitate the development of correct software through formal verification. It was designed to integrate program specifications and automated proofs, aiming to make the process of proving program correctness more accessible and efficient.

About Dafny

Strengths of Dafny include its integrated approach to specification and verification, user-friendly syntax, and strong support for automated theorem proving. Weaknesses involve a steep learning curve for beginners and limited support for certain advanced language features. Competitors include Coq, Isabelle, and Z3, which also focus on formal verification and theorem proving.
