Front-End EngineerHouston, TX
I build React and TypeScript applications that make large spatiotemporal datasets fast and usable in the browser — 2D/3D map interfaces, WebGL rendering, and interactive analysis on satellite and sensor data.
About
I'm a front-end engineer with five years building production web applications and a decade working with geospatial data. The through-line is making complex spatial systems feel operable: constellation-scale views that stay smooth, workflows that match how domain experts actually think, and interfaces that hold up when the dataset is huge.
Recently that has meant owning frontend delivery and technical direction for satellite geospatial products — translating requirements from operators and engineers into intuitive tools, growing a shared component library across applications, and putting tests in CI so regressions don't ship. I like the work that sits between product, performance, and people.
