About
Hi, I'm Sean — I build small, fast, useful tools for the web. Photo Date Changer is one of them.
I'm a full-stack developer — Rails and PostgreSQL most days, with a long tail of Python, PHP, JavaScript and Swift behind me. Nearly everything on this page started as something I wanted to exist and couldn't find, so the projects tend to be small, single-purpose and shipped rather than endlessly polished.
Some of them are free and stay free — no account, no upsell, nothing to cancel. The ones that cost real money to run are paid, with a free tier or trial first so you can decide before you pay. You'll always know which kind you're looking at before you hand over anything.
Photo Date Changer is one of the free ones, and it goes a step further: your photos never leave your device. Every tool here runs in your browser, so there's no upload and nothing for me to store.

Other things I've built
A few other things I run — some free, some paid, all of them free to try.
The truly free to-do list — open it and start checking things off. No signup, no login, no paywall.
Turn any article into a podcast — paste a link, get back a natural two-voice conversation about it. Generating audio costs real money, so it's paid after the first few episodes.
Log workouts with a conversation. Type “bench 3x8 at 185, squats 5x5 at 225” and it sorts out every exercise, set, rep and weight. Subscription, with a 14-day trial and no card up front.
Free surveys, made simple. Build a questionnaire, share a public link, and watch the responses land — no account needed on either end.
Free kanban boards that just work. Spin one up instantly, then use as much or as little structure as you actually want.
My own site — writing on Rails, deployment and building things for the web, plus whatever I'm working on next.
About Photo Date Changer
Photo Date Changer started as a single tool for changing the date on photos. It's growing into the easiest place to fix photo metadata of any kind — dates, location, orientation, format and more.
Our one rule: your photos never leave your device. Every tool runs in your browser using JavaScript, so there's no upload, no storage and nothing for us to see. That makes the tools fast, private and free to run at any scale.
