UCSD Dining App Redesign — Group Project

The existing UCSD dining app gave students with dietary restrictions no efficient way to find suitable meals across campus. Every visit meant manually checking each location one by one.

We redesigned the app to put dietary filtering front and center — a persistent quick-filter bar shows matching item counts per location in real time, so students know before they walk over.

A fully working prototype includes dietary preference defaults, cart, checkout, and order history — all within UCSD's official brand system (navy, gold, turquoise).

Can a college quarterback's combine numbers and stats predict whether they'll get drafted into the NFL? This COGS 108 group project set out to find out.

Using NFL Combine and NCAA datasets, we explored whether measurables like 40-yard dash time, TD/INT ratio, and total yards could reliably separate drafted from undrafted QBs.

The answer was nuanced: trends exist, but no single metric is decisive. The draft reflects a complex mix of performance, athleticism, and context — a finding with real implications for how scouting data should be visualized for decision-makers.

SD Softwater
Water Softener Installation Business — Brand & Web

SD Softwater is a water softener installation business I founded in San Diego, operating under a deposit-based subcontractor model. The brand and website had to do the work of a sales team.

The site is designed around a single conversion goal: capture the lead. Clear headline, service area callout, and a functional lead capture form above the fold.

The visual identity uses a San Diego skyline theme to anchor local trust. Typography and color were chosen to feel professional without being corporate, and the layout is optimized for mobile-first browsing where most local service searches happen.

I'm currently seeking entry-level UI/UX or Product Design roles where I can bring my background in Cognitive Science and human-centered design to real-world products.

I believe the best designs are invisible — they guide users effortlessly, reduce cognitive load, and make complex things feel simple.
