Data-drivenCustomer-focusedOutcome-oriented

01Who am I?

Born and raised in Philly. BS in Accounting + MIS. I build product in payments, cart, checkout, and fraud where clarity, trust, and conversion meet.

02What do I care about?

Simple UX, measurable impact, and craft. Also: books, tennis, and building side projects that teach me new tools.

03How do I help?

I turn messy user journeys into clean flows: diagnose friction, prioritize the leverage points, ship experiments, and scale what works.

04What keeps me interested?

Problems that don’t have obvious answers — and teams willing to slow down (when you can afford it) to find them, then ship fast and learn faster.

Personal Work

Latest project · Live

FirstFinder

A free, open-source catalog for people who collect things.

Visit firstfinder.app → View GitHub →

Situation

Collectors track receipts, purchase prices, and values in spreadsheets that get away from them, and the existing tools are built for dealers with thousands of items, not the hobbyist with forty books.

Product

I designed and built FirstFinder end to end. Take a photo and AI fills in the title, edition, printing, condition, and a search-grounded value range. It keeps receipts, cost basis, and sales in one ledger, works offline at book fairs, and lets collectors share a read-only collection page.

Wedding Website

Visit denniesandkassidy.com → View GitHub →

Situation

After getting engaged in 2024, we needed a wedding website to manage RSVPs, registries, and guest communication. Existing platforms felt overly templatized and confusing from a guest experience standpoint.

Product

I designed and built a custom wedding website focused on simplicity, clarity, and delight—defining requirements from firsthand frustration, prototyping flows, and shipping a polished end-to-end experience.

Dog Food Calculator

Try the calculator →

Situation

Feeding guidelines are generic and often lead to weight gain. With multiple foods and supplements, understanding proper portions becomes even more complex.

Product

I built a calculator that incorporates caloric density across foods to better estimate daily intake based on real nutritional needs.

Budgeting App

Watch the demo →

Context

Off-the-shelf budgeting tools didn’t match how I think about money, so I built a custom app on Salesforce tailored to my workflow.

The Book Barterer

Context

A personal project born from a lifelong love of reading and curiosity about pricing, inventory, and marketplace dynamics.

Product

An e-commerce site for used and rare books, optimized through iterative pricing, feature prioritization, and customer feedback.

Job Application Tracker

Open the tracker →

Situation

Tracking job applications manually is error-prone and mentally taxing, especially when responses never arrive.

Product

A spreadsheet-based system with automation, dashboards, and clear status tracking to reduce cognitive overhead during job searches.

Product Portfolio Website

Context/Product

I designed and vibecoded this website! It was an incredible learning experience for me coming from a non-technical/non-programming background. Take a look at the website, explore, and see my Github! And as always, I'm open to feedback! This is a labor of love and this website transformed from a Google site, always iterating, always making it better.
