Orlando, Florida, United States
Summary
🤩
RockstarJoel Martinez is a Principal Software Engineering Manager based in Orlando with over 20 years in software and 14 years in senior engineering leadership, currently leading green-field efforts at Microsoft including the zero-downtime launch of Microsoft Q&A and active AI projects. He combines deep .NET and C# expertise with a track record of shipping cross-platform libraries and documentation tooling—contributions to high-profile open-source projects like Mono and Mono.Cecil highlight his low-level metadata and tooling chops. Joel has moved between hands-on engineering and technical leadership repeatedly, from building custom CMS and API doc pipelines to scaling high-throughput trading systems and mobile apps. He’s equally comfortable refactoring parser-edge cases in open source repos as architecting production documentation search and answers experiences, bringing a pragmatic blend of product focus and developer empathy.
