Nicola Mometto
Backend Engineer at Metabase
Stevenage, England, United Kingdom
Summary
🤩
RockstarNicola Mometto is a backend engineer with 14 years of experience building distributed, high-performance systems and compiler tooling, now working at Metabase from Stony Stratford. He has deep expertise in functional languages and compilers—contributing to high-profile open-source projects like ClojureScript, core.async and the Z3 OCaml bindings—and has repeatedly fixed core compiler and analyzer issues. At Imandra he led R&D and a team of six to design a fully parallelizable reasoning engine, custom SMT solvers, and tools for formal-spec correctness and log validation for financial systems. His background spans hands-on systems work (package manager portability and install scripts for opam) to designing fault-tolerant network protocols and distributed client-server architectures. Known for improving robustness and performance at the language and infrastructure level, he pairs rigorous formal methods experience with practical production deployments. An often-overlooked strength is his history of evolving developer tooling and analyzers, enabling others to scale complex language-based systems more safely.

Clojure lint tool
Role in this project:Back-end Developer
Back-end DeveloperContributions:48 commits, 2 PRs, 3 pushes in 4 years 7 months
Contributions summary:Nicola primarily worked on the Clojure lint tool, `eastwood`. Their contributions focused on improving the analysis process. They modified the analyzer to correctly handle macro expansions, fixed errors related to duplicate class definitions, and addressed namespace evaluation issues. Further, the user implemented a custom variable creation method and removed manual class loader binds to streamline the code analysis process.
