Monte Carlo Cloud Simulation

I built a Python photon-transport simulation for a UMBC physics course, then graded other students' implementations as a teaching assistant. Includes an interactive reconstruction.

Service Operations Map

I built a touchscreen customer map with pricing zones, service-due heatmaps, and upsell flags. A septic-services business adopted it to replace its sticker wall map.

ncarnate: Scientific Data Conversion

One recorded Arctic sea-ice sample: HDF4 source 99% and netCDF4 output 99%. These two stored values match.Arctic sea-ice sampleHDF499%netCDF499%Stored values match

I rebuilt a Python converter for supported HDF4 and netCDF files, checking converted values against their source. Published on PyPI and conda-forge.

• Enterprise applications. Reduced document-generation time from more than 30 seconds to under one second, and built imports for pricing tables embedded in spreadsheets and images.
• Independent engineering. Delivered data-analysis and automation work, and co-built a FastAPI and PostgreSQL backend for device telemetry.
• Research software. Wrote two Python tools during my NASA internship, both filed as NASA-owned New Technology Reports.
