Summary
馃ぉ
RockstarAlexander Gryzlov is a research software engineer with 15 years' experience applying programming language theory, type-based formal verification, and mechanized reasoning to systems and computational domains. Based at IMDEA Software Institute, he blends proof engineering and compiler development on projects spanning concurrent separation logic, refinement/liquid types, homotopy type theory, and automated static analysis. He is an active open-source contributor to the Idris dependently typed language, contributing core features, bug fixes, and helper libraries that reflect deep familiarity with language internals. Comfortable across concurrency, distributed systems, cryptography, compilers and probabilistic modelling, he favors compositional, mechanized mathematical approaches such as constructive/synthetic mathematics and applied category theory. Colleagues rely on him to translate advanced type-theoretic ideas into practical tooling and provably-correct implementations.

Back-end Developer
Back-end DeveloperContributions:28 commits, 31 PRs, 138 comments in 2 years 7 months
Contributions summary:Alexander primarily contributes to the Idris programming language project. Their work includes implementing core language features, such as adding functions like `pow`, `foldlM` and data structures like `SortedMap.singleton`. They also fix bugs, like typos and improve the language's internal functions, such as making some `divides` views public and fixing `Core.Execute` in the Idris language execution. Additionally, the user updates documentation and adds new helper functions to existing modules, such as `runWriter`, demonstrating a strong understanding of the language's internals.
