I trained as a biologist. At San Jose State I spent two years scanning ant specimens and building 3D models of their mandibles — slow work that taught me to trust a measurement only as far as its method. What changed my direction was five years at a medical equipment store. I fitted walkers, wheelchairs, and electric scooters, and what someone took home usually came down to cost and coverage, not what fit them best. The science was rarely the constraint. For five years I worked at a medical equipment store, fitting walkers, wheelchairs, and scooters for patients and their families. What stuc

Overview

During my externship with Schreiber Foods, I tackled the challenge of transforming food manufacturing waste into valuable resources. The goal was to contribute to the company's ambitious target of achieving 100% waste diversion by 2030. I engaged deeply with real data, analyzed operational hurdles, and explored practical circular economy solutions across multiple facilities.

What I've accomplished

I produced a set of quantitative deliverables: a tabulation of waste flows and diversion rates, a cross-facility comparison highlighting best and worst performers, a regional provider map and notes, and a final presentation with proposed investments, payback ranges, and estimated annual revenue.

SQL & Database Architecture Externship with Breaking Games

Turn six messy CSVs into an analytics database and a Q4 dashboard that drives real business decisions. SQL + Claude.

Analytics Database DesignData AnalysisSQL FundamentalsData Storytelling

Overview

The project converted six messy CSV files into a structured analytics dataset and produced a Q4 dashboard. The work mapped source tables, documented their fields and quality issues, and defined the schema and relationships used to load the analytics database.

SQL & Database Architecture Externship with Breaking Games

What I've accomplished

I produced a data inventory and a query log that catalogued six raw data sources, documented missing dates, NULLs, and grain mismatches, and recorded the initial SQL used to explore revenue data.

Project breakdown

I audited six raw data sources, described what each table contained and its limits, ran SQL queries against a provided SQLite export, and compiled those observations into a running Holiday Game Plan document that recorded totals and data issues.

Access

A fragmented product dataset was unified by building dim_product and linking tables with primary/foreign keys. I joined events, sessions, carts, and sales, aggregated product revenue and units, and produced a ranked reorder recommendation.

What I've accomplished

Project breakdown

Inside a Zero Waste FacilityI analyzed the Shippensburg facility's waste report and summarized its waste streams, diversion methods, and diversion rate.

Cross-Facility Data Analysis & Plant SelectionI built a diversion comparison chart showing each U.S. plant's waste diversion rate.

Investigate Regional BarriersI mapped local waste services and recyclers near the Smithfield facility, listing providers, distances, and material specializations.

Designing a Diversion StrategyI drafted a facility diversion strategy report recommending partnerships, knowledge transfer from a nearby plant, and targeted preprocessing investments to reduce comingled waste.
