Perpetual Tinkerer

I build things that help people.

I'm Taylor, a builder based in Franklin, Tennessee. I spent years working inside digital products, close enough to see exactly what users needed but without the ability to build it myself. So I learned.

Now I ship small, practical apps under Shivers LLC with one filter: does it actually help someone? Flip or Pass is my main focus right now, with more in the works.

Case Study

Flip or Pass

Problem

Resellers need fast buy/no-buy decisions at thrift stores and garage sales. Generic eBay calculators use flat fee estimates and dump raw numbers — no clear verdict, no category-specific accuracy.

Solution

Built a mobile-first profit calculator that uses 50+ category-specific eBay fee schedules, analyzes up to 200 live listings, and delivers a clear FLIP, PASS, or MAYBE verdict with full profit breakdown.

Highlights

  • Production SaaS with Stripe subscription billing
  • Barcode scanning for in-store product lookup
  • Sold price data and market intelligence for Pro users
  • Circuit breaker patterns for upstream API resilience
  • Sentry monitoring with session replay on errors
