About

Jason Shultz

I'm a senior full-stack engineer with over 20 years of experience building web applications and the systems behind them. I've worked across pharmaceutical logistics, nonprofit technology, EdTech, e-commerce, and print production, the kind of domains where software failures have real consequences.

These days I split my time between leading infrastructure and engineering for a fleet of production sites and writing the code myself. I've built warehouse management systems handling $200M+ in distribution and multi-tenant platforms on Next.js and Postgres. I've also run the security audits, legacy migrations, and late-night incident calls that keep everything else alive.

When you hire me, the person who designs your system is the same person who knows what happens when it breaks. I help teams make architectural decisions they won't regret in two years.

Outside work

I still build things nobody asked for: side projects, tools I use every day, and whatever I'm curious about this month. See the Lab →

Got a system nobody wants to touch?

A legacy platform held together with tape, a business still running on spreadsheets, or infrastructure everyone's afraid to restart. I've been handed all three. Tell me what you're dealing with.
