Jimpo contributed to the IrreducibleOSS/binius and binius64 repositories, building cryptographic infrastructure and protocol tooling for zero-knowledge proof systems. He engineered features such as parallelized witness table construction, modular field arithmetic, and a Fiat-Shamir transcript system, using Rust and Assembly to optimize performance and reliability. His work included refactoring core algorithms, enhancing memory management, and improving benchmarking accuracy for polynomial commitments. Jimpo also led the migration from binius to binius64, providing clear documentation and a structured transition path. Throughout, he emphasized code quality, test determinism, and maintainability, demonstrating depth in systems programming, cryptography, and backend development.

In September 2025, delivered a clear deprecation notice and migration path for the Binius project in IrreducibleOSS/binius, transitioning stakeholders to Binius64. Focused on user-facing documentation and announcing the successor to minimize confusion and support overhead. Milestone committed with the message 'Binius is dead, long live Binius (#833)'.

August 2025 (2025-08) – Focused on strengthening benchmarking reliability for polynomial commitments in IrreducibleOSS/binius. Delivered a targeted fix to the NTT initialization path used in polynomial commitment benchmarks, eliminating an incorrect initialization that could skew results and ensuring the NTT is configured with the correct subspace for accurate measurements. The change is small, low-risk, and well-contained in the bench path, with commit [bench] Fix poly_commit bench (#829). This work lays a firmer foundation for data-driven optimization and performance comparisons.
