# Joshua Shepelsky

> Senior full-stack engineer in Charlotte, NC (remote). I'm Josh. I've spent 8+ years shipping production web platforms. Recent ones include a multi-tenant certification platform I built from an empty repo and a paid directory rebuild where I was tech lead and designed the move off a legacy platform. I've also done hosting and caching work on a site with millions of monthly visitors. Lately a lot of what I build has AI in it, like an estimating API on Claude and Amazon Bedrock and an iPhone app that reads receipts with Claude vision. Microsoft Copilot cited the collision repair locator I built 2,200 times in 60 days.

## Case studies

- [Collision Estimate AI](https://www.joshuashep.com/work/collision-estimate-ai/): An API that turns damage photos into a line-item collision repair estimate, and explains insurance estimates in plain language, in 16 languages.
- [Collision Repair Locator](https://www.joshuashep.com/work/collision-repair-locator/): A public directory of 4,700+ certified collision centers. In its first months it went from zero to 57,000 search impressions and 2,200 Microsoft Copilot citations.
- [TossCost](https://www.joshuashep.com/work/tosscost/): A native iPhone app that reads grocery receipts with Claude vision and shows what the food you throw away actually costs.
- [Autism Friendly Care](https://www.joshuashep.com/work/autismfriendlycare/): A free national directory of healthcare practices experienced with autistic patients, with the accommodation details families need before they book.
- [essentials for Claude Code + Codex](https://www.joshuashep.com/work/essentials-plugins/): An open-source review and testing toolkit for Claude Code and Codex that detects your stack instead of hardcoding one.

## More trails on the map

- [Certification platform](https://www.joshuashep.com/#trail-certification-platform): A multi-tenant platform for a collision repair certification network, built from an empty repo. Shop, OEM, and management portals share one codebase, with geotagged photo checks and Stripe billing by card or ACH.
- [Packlark](https://www.joshuashep.com/#trail-packlark): A native iPhone packing app. 16 engines on the phone build the list and give a reason for every number, and Claude adds suggestions on top.
- [No Bulls News](https://www.joshuashep.com/#trail-nobullsnews): An AI news site that publishes on its own every hour. It groups coverage of each event from 44 feeds, Claude writes one short, blunt version, and a second model checks every claim against the sources before it runs. Fair warning: it swears.
- [TradeChickens](https://www.joshuashep.com/#trail-tradechickens): A rules engine for stock and options trades on the Tradier brokerage API. The same code runs backtests and trades, and nothing reaches the broker until I approve it.
- [Art Hanging Helper](https://www.joshuashep.com/#trail-arthanger): A free calculator that tells you where to put the nail, for one piece or a whole gallery wall, plus 19 how-to guides.
- [Design by Flora](https://www.joshuashep.com/#trail-design-by-flora): I rebuilt the site for a wig studio in Teaneck, NJ, and set up the marketing behind it: Google Ads, call and form tracking, and local search markup. In the first 10 weeks it brought in 32 booking requests and 40 call taps. Paid leads cost about $54 each, for wigs that sell for $2,000 and up.
- [Healthcare directory rebuild](https://www.joshuashep.com/#trail-healthcare-directory): I was tech lead on the rebuild of a healthcare publisher's paid directory of professionals. I also designed its move off a 45,000-account legacy platform, with no mass password reset.

## Background

- Healthcare media: Tech lead on the rebuild of a paid directory of healthcare professionals: geocoded search, listing tiers, Stripe billing, moderated reviews, and a JWT-secured REST API.
- Automotive: Led four engineers and one QA through 30+ two-week sprints on parts software, and ran a security overhaul of a legacy PHP codebase.
- E-commerce: Where I started: building and running a WordPress/WooCommerce store with custom PHP and JavaScript.
