PROFILE

Sean Martin

Worked on the chanzuckerberg/cryoet-data-portal and backend, delivering features that improved data visualization, mesh processing, and user navigation for tomogram datasets. Leveraged Python, JavaScript, and React to implement cross-platform packaging, mesh precomputation, and a tomogram selection dropdown, enhancing both backend reliability and frontend usability. Addressed data unit consistency by scaling mesh files and standardizing resolution units, while dependency management and environment stabilization reduced deployment issues. Refactored UI components for maintainability and updated test coverage to ensure robust user workflows. The work emphasized backend data processing, scientific visualization, and frontend development, supporting scalable, user-friendly scientific data exploration.

Dec 1, 2025

December 2025 (2025-12) — CryoET Data Portal (chanzuckerberg/cryoet-data-portal). Focused on delivering a robust, user-friendly tomogram navigation experience and solidifying frontend quality through refactors and test alignment. The primary deliverable was a new Tomogram Selection Dropdown in the Neuroglancer viewer, with behind-the-scenes refactoring and UI refinements to improve usability and maintainability.

Jul 1, 2025

July 2025 performance- and reliability-focused month. Key deliveries include a Mesh Visualization and Precomputation feature enabling precompute and visualization of triangular meshes and mesh groups, with multiresolution mesh support from GLB files, and an updated visualization config importer to render mesh layers. Environment stabilization was achieved through critical dependency upgrades (Neuroglancer, igneous-pipeline) and addition of fastmorph and opencv-python, improving stability and compatibility across the backend. No critical bugs were reported; focus remained on reliability, data visualization readiness, and groundwork for scalable feature rollouts.
