I build things that
measure, model & ship.
Engineering at the seam of quantitative finance
I'm David Mroz, a Computer Science, Data Science & Economics student at UW–Madison. I turn economic intuition into software: quant-finance tooling, AI systems, and products with real users.
At a glance
Where economics meets engineering
I like the place where economics meets engineering: a market idea becomes a model, and a model becomes software somebody opens every day.
At UW–Madison I'm carrying a triple major in Computer Science, Data Science, and Economics while building real products on the side. That combination is the point: I can reason about why a financial idea matters, design the math behind it, and ship the code that makes it usable.
Right now that means a quantitative-finance platform, a cross-platform nutrition app, a browser extension growing organically, and frontier edge-AI research with an industry-mentored lab. I care about things that are numerically correct, not just things that look right.
Quant & markets
Options payoffs, Greeks, implied-vol surfaces, event pricing. Institutional-grade tooling for retail investors.
AI & ML systems
LLM-driven automation and on-device computer vision: privacy-preserving analytics that run at the edge.
Full-stack shipping
Next.js, React Native, Supabase. I take products from idea to deployed, with real users and real data pipelines.
Economic reasoning
Optimization, modeling, and the why behind the build. Engineering decisions grounded in incentives and trade-offs.
Things I've built & shipped
A platform, an app, an extension, and a research build. Each live or in active development.
ThetaViz ↗
A full-stack quantitative-finance platform giving retail investors institutional-grade tooling: options-strategy payoff modeling, Greeks visualization, implied-volatility surfaces, event-pricing estimates, fundamentals graphs, and a live portfolio tracker. Live and feature-complete.
BadgerBites ↗
A cross-platform nutrition app for UW-Madison students that turns live Nutrislice dining-hall data into personalized, macro-aware meal recommendations. Friendly accountability, never guilt-trips. Supabase backend for auth, preferences, and meal logging. Launching Aug 2026.
MyUWPlus ↗
A Chrome extension that injects historical class GPAs (MadGrades) and Rate My Professor ratings straight into UW's course-registration portal. Custom DOM scrapers and live API integration. Growing organically to 50+ users with 1–3 installs every day, no marketing.
SAIL — Edge-AI Research ↗
Selected for UW-Madison's competitive CDIS / N+1 cohort at the College of Computing & AI. On a 4-person, industry-mentored team building on-device computer vision and spatial analytics for brick-and-mortar retail. Privacy-preserving: no customer data leaves the store.
Where I've worked
Technical Researcher
Selected for the competitive CDIS/N+1 cohort to build a production AI application with industry mentorship. Engineering LLM-driven workflow automation across local and cloud-hosted model architectures on a 4-person team.
Data Analytics Consultant
Built interactive visualizations from US Census, public, and transit datasets to analyze community access by ZIP code. Presented equity findings to executive leadership at the Boys & Girls Club to guide resource-allocation decisions.
President & Curriculum Director
Led a 4-year STEM nonprofit (~200 volunteer hours), directing 7 instructors across a Python / JavaScript / Arduino curriculum. Designed a progressive engineering curriculum for 5th–6th graders, scaling operations year over year.
Awards
1st Place, Kohl's Emerging Talent Summit
Designed a dual-pronged customer-engagement strategy and pitched it to Kohl's leadership in a 9-minute final. Case competition, 2026.
Goldman Sachs Possibilities Series
Selected participant in Goldman Sachs' early-talent program.
Dean's List, UW-Madison
Recognized for academic standing across a demanding triple-major course load.
