Rockstar🎓
Top SchoolTrevor Manz is a founding engineer and full-stack developer with 8 years of experience bridging research-grade bioinformatics and production software, now based in New York. Holding a PhD from Harvard in Bioinformatics and an MPhil from Cambridge, he brings deep domain expertise from academic research into practical systems engineering. He has contributed notable open-source work on geospatial and data-handling projects—improving async decoding in geotiff.js and flattening zarr support in loaders.gl—alongside backend contributions in Rust for the ultrafast uv package manager. Trevor blends low-level performance tuning with higher-level usability and documentation, having also improved fsspec reference handling and written interactive examples for Altair. As a researcher-turned-founder, he’s comfortable shipping production features, writing tests, and iterating on developer ergonomics across languages and stacks. A small but telling habit: his GitHub bio points to a personal script (curl -sL manzt.sh), suggesting a preference for pragmatic, scriptable tooling and fast workflows.
