01. About me

I'm a full-stack developer focused on end-to-end product delivery — from designing FastAPI backends and React frontends to deploying production-ready cloud applications from the ground up.

I specialize in processing multi-source datasets, working with relational and spatial databases (PostGIS, Supabase), and integrating cloud and AI APIs to build tools that are both powerful and easy to use.

02. Projects

well-viewer

A high-throughput risk-scoring pipeline evaluating 110,000+ historical and orphaned wells across Ohio. Implements the USGS Woda et al. framework to weight multi-variable risk profiles including population density, water source proximity, well age, and satellite-detected emissions.

    2026 — Present
    • Led end-to-end development of a geospatial platform tracking orphaned and abandoned oil wells across Ohio's 88 counties as lead developer, using PostGIS, FastAPI, Supabase, and React
    • Engineered a high-throughput risk-scoring pipeline that evaluated 110,000+ historical and orphaned wells across Ohio, implementing the USGS Woda et al. framework to weight multi-variable risk profiles including population density, water source proximity, well age, and satellite-detected emissions.
    • Built Python ETL pipelines ingesting and normalizing multi-source datasets (ODNR well records, USGS NHD hydrography, HIFLD critical infrastructure, ODOT roads, OSM) into a unified PostGIS schema with sub-second spatial query performance
    • Integrated MethaneSAT L3/L4 satellite emissions data via the Google Earth Engine API to overlay methane plume detections on candidate well sites
