Summary
🤩
Rockstar🎓
Top SchoolDan Rollo is a seasoned software engineer and long-time open source committer with 18+ years building enterprise systems, multimedia platforms, and developer tooling. He focuses on clean, simple designs, rigorous unit testing, and automated CI to keep large codebases reliable and maintainable, and he’s known for persuading teams to adopt these practices. Dan has contributed to notable OSS projects such as JNA and the Rust libgit2 bindings (git2-rs), fixing low-level bugs and improving native interoperability—work that reflects deep systems and cross-language expertise. His professional history spans product and services roles across Sonatype, ETS, and Composite Software where he delivered integrations, custom drivers, and performance-sensitive systems. Based in Central Jersey and preferring to be coding rather than commuting, he seeks remote or very-local positions and brings both hands-on engineering and mentoring experience to distributed teams. An understated strength is his ability to reduce build and feedback cycles—historically cutting multi-day builds to hours—to accelerate team productivity.
