Summary
🤩
Rockstar🎓
Top SchoolAndreas Lynge is a pragmatic software/back-end developer and committed community volunteer based in Copenhagen with 13 years of experience combining technical contributions to formal proof projects with hands-on operational roles. He has contributed bug fixes and feature work to notable Coq projects such as Rocq Prover and the HoTT library, focusing on tactics, universe polymorphism, and formalizing algebraic structures—work that reflects comfort with rigorous, mathematical codebases. Outside open source, Andreas has extensive practical experience in logistics, administration and library/archive support from roles at FødevareBanken and DR, where he handled newsletters, inventory, and archival tasks. He prefers structured, part-time work (flexjob 11 hours/week) due to reduced work capacity and brings careful attention to detail and sustainability in both professional and personal life. Social and curious, he enjoys cultural and scientific topics and values community engagement, making him well-suited for supportive operational or library-style roles that bridge technical and human-facing work.

A Coq library for Homotopy Type Theory
Role in this project:
Back-end Developer
Back-end DeveloperContributions:36 reviews, 55 commits, 49 PRs in 2 years 3 months
Contributions summary:Andreas contributed to the development of a Coq library for Homotopy Type Theory, adding definitions related to universal algebra, including algebras, homomorphisms, and isomorphisms. Their work involved creating and modifying files with definitions for operations, and homomorphisms, as well as the definition and implementation of the product algebra and quotient algebra and their properties. The contributions include proofs of theorems, indicating a focus on formalizing mathematical concepts and structures within the Coq environment.

rocq-prover/rocq
May 2019 - Aug 2019
The Rocq Prover is an interactive theorem prover, or proof assistant. It provides a formal language to write mathematical definitions, executable algorithms and theorems together with an environment for semi-interactive development of machine-checked proofs.
Role in this project:Back-end Developer
Back-end DeveloperContributions:13 commits, 6 PRs, 33 comments in 3 months
Contributions summary:Andreas primarily contributed to the Rocq Prover project by fixing bugs and improving the interaction with the underlying Coq system. The commits reveal adjustments to the SSR (SSReflect) plugin, addressing issues with universe polymorphism and term unfolding/folding. Furthermore, they worked on making the `discriminate` tactic compatible with the HoTT library and refined the rewrite tactic to utilize registered elimination schemes.
