Built by a breeder. For breeders.

I have been in the breed world my entire life. I did not discover breeders as a market segment. I grew up in shows, learned pedigree records before I learned algebra, and built my first breeding software because nothing on the market worked for the way I actually breed.

Breed Ledger is the result of doing both things long enough to know what the other side needs.

I grew up in the dog world

My family bred and showed ADBA American Pit Bull Terriers starting when I was five years old. Shows, conditioning, studying bloodlines from the ground up. The dog world was not a hobby for us.

Around 2005 I shifted focus to American Bullies when the breed was still being built in real time. There was no established standard, no registry with decades of precedent, no handbook telling you what the breed was supposed to look like in ten years. A small group of breeders was actively defining it, and I was part of that group.

At twelve years old I was involved in establishing ABKC during the breed's formative years. That understates it. I was in the room when the rules were being written, when the standard was being argued over, and when the infrastructure that the current ABKC community now takes for granted was being built from nothing.

I competed as a junior adult and won Best in Show under ABKC. After college I made group placements in UKC and was part of the founding group that established the American Bully breed club within UKC. Two registry builds from the inside, both during the most consequential period of the breed's history.

When I talk about what a registry needs to do, what a pedigree record actually tracks, or what a breeder needs to show a serious buyer, I am not guessing. That firsthand experience is built directly into the breed club and registry tools on the platform.

I still breed today

I breed crested geckos under Geckistry. Not past tense. Right now. Geckistry is a full production breeding operation with its own website, custom e-commerce, and a genetics platform I built myself. The animals on that site come with full pedigree trees, genetic profiles, and parent documentation, because I needed those tools and built them.

ReptiDex started the same way. No adequate breeding records tool existed for reptile breeders, so I built one. It launched March 4, 2026. In its first 20 days: 73 registered users, 259 animals tracked across 69 collections, 268 feedings logged, parent-offspring linking, multi-generation pedigree trees, and QR-code-to-live-record functionality. ReptiDex is a live registry in production.

It also proved that the technology stack works. The genetics engine, the pedigree system, and the animal management tools in Breed Ledger all have roots in problems I solved first in my own operation. These are not features I designed by asking breeders what they wanted. They are features I built because I needed them myself.

9+ years as a professional engineer

After college I spent nearly a decade building software in sectors where mistakes are expensive: fintech, HIPAA-compliant healthcare systems, and federal data pipelines for agencies including CBP, ICE, and FEMA. Building regulated systems for government and clinical healthcare teaches you a different standard of reliability than building marketing websites.

Those careers were not in breeder software. They were in high-stakes, complex systems that had to work correctly. The same standards I applied to clinical data and federal government systems are the ones I apply to Breed Ledger, because breeders are trusting the platform with decades of lineage records, buyer relationships, and the documentation that makes their breeding programs credible.

The engineering background is not the lead on this page, and it should not be. Every tool on Breed Ledger was designed first as a breeder problem, then solved as an engineering problem. That order matters.

Why this platform exists

Every breeder software product on the market was built by a developer who found breeder clients. Breed Ledger was built by a breeder who also happens to be a senior engineer. That is not a marketing line. It is the reason every feature on this platform works the way it does.

The problems Breed Ledger solves are not hypothetical. I lived them: a Wix site that could not display a pedigree tree, a spreadsheet that broke every time I needed to track a litter, Facebook albums that buyers never checked, DMs for buyer inquiries that got buried. I patched these problems for years before I had both the breeding knowledge and the engineering skills to build what actually worked.

ReptiDex and Geckistry proved the technology works in production with real breeders and real animals. Breed Ledger makes it available to every breeder, for every species. And the same infrastructure that powers individual breeder programs also powers breed organizations running their own registries on the platform.

The goal is straightforward. One platform where a breeder signs up, adds their animals, picks a template, and has everything they need. No patchwork. No plugins. No starting from scratch.
