Sample Builds
Real builds you can click through.
Every project below was built from scratch to demonstrate the architecture, craft, and attention to detail that goes into a Holtz Digital build. Open any one of them and use it like a customer would.
QuickShow
A modern movie ticketing platform designed to feel fast, intuitive, and seamless across every interaction — engineered end-to-end as proof of advanced product capability.
E-Commerce Platform
A production-grade e-commerce platform built as a Turborepo monorepo — featuring a customer storefront, admin dashboard, and four independent microservices communicating over Kafka.
Backend services spin down during inactivity — allow about a minute for them to wake up on first load.
Rachel Moretti — Buffalo Real Estate
A complete residential real estate site for a fictional Buffalo agent, built from a design system rather than a template. The listing pages are structured the way an IDX feed actually arrives, and the MLS display rules — attribution, disclaimer, withheld addresses, fields that may never be shown — are enforced in code instead of left to whoever edits the page.
Rachel Moretti is a fictional agent — the brokerage, listings, prices, statistics and reviews are all invented, no property shown is for sale, and the site is deliberately kept out of search results. A live build for a real agent would need their broker's IDX authorization and a compliance review before launch.
Ridgeway Heating & Cooling
A custom WordPress theme built from scratch for a fictional Buffalo HVAC contractor. Six services across sixteen Western New York towns generate ninety-six landing pages, each one written around what the housing stock in that town is actually like — plus HVACBusiness schema, 24/7 emergency call handling, and a quote form that accepts a photo of the rating plate.
Ridgeway is a fictional company — the address, phone numbers, licence number and reviews are invented, and the site is deliberately kept out of search results.
Larkin & Vine
A custom WordPress theme built from scratch for a fictional Larkinville restaurant. Every dish is a structured record with its own price and dietary tags — which is what lets the same content render the menu page, feed Google's Restaurant and Menu structured data, and stay editable by a manager on a Tuesday afternoon.
Larkin & Vine is a fictional restaurant — the address, phone number and reviews are invented, and the site is deliberately kept out of search results.
Harbor Lights
A fully custom WordPress theme built from scratch as a concept for a community/ministry-style organization — no page builders, no generic templates. Clean PHP, performance-focused, and easy for non-technical staff to manage.
Far Country Wear
Far Country Wear is a live custom clothing website — a parable-themed apparel brand designed, built, and operated end-to-end, from AI-assisted product art to checkout and fulfillment.
