Full-stack developer.
15+ years building, owning, and shipping.
I build things end-to-end, from messy legacy systems to production-ready products that stick.
Get in touch// about
I'm Juan Hernandez, and most people call me Jay. Born in 1988 in the Dominican Republic, I've spent most of my life in NYC and now live on Long Island with my wife and three kids. I got my start in web at WebMD, working on the Medscape editorial team before moving into development roles at agencies and startups across the NYC area. Early on I learned to own projects end to end, and that approach has stayed with me ever since.
For nearly a decade I was a core developer at Socialix, an influencer marketing platform used by brands and agencies. I built and scaled the product from the ground up: CRM, campaign workflows, social platform integrations, automated post metrics. A long run of shipping real features for real users.
These days I'm a Web Developer IV at AAA Northeast, building member-facing web applications: membership management, vacation booking, internal tooling. Outside of work I build BookTrail, a family reading tracker, as a way to stay sharp and try new things. Nearly two decades in, I still find it interesting.

Simple Machines Forum
~2005 – 2007Support Specialist → Community Contributor
Before making the jump to professional development, I contributed to the SMF open source forum community. Started as a support specialist and grew into an active code contributor, writing forum conversion scripts that let users migrate from other platforms (like phpBB) to SMF and publishing mods that extended SMF's core functionality. An early lesson in reading unfamiliar codebases, shipping work used by real communities, and the value of showing up consistently.

BookTrail
A family reading tracker built for parents and kids.
A full-stack web application that helps families build lasting reading habits. Parents manage a shared dashboard with individual child profiles, reading goals, achievements, and a curated library of 80+ children's books sourced from the Open Library API. Kids get their own "Kid Mode," a simplified, child-friendly interface with QR-code login so young readers can jump in without a password.
Features include session tracking with an active reading banner across all pages, wishlists, genres, family book collections, and a Filament-powered admin panel.
Built end-to-end with Claude Code. My first deep dive into AI-assisted development.
