New York City · builder

I build small, fast tools that make everyday life a little less annoying.

I'm Jacob. Most of what I make started as a problem I had at 11pm — a game I wanted to watch without spoilers, a train I was tired of guessing at, something my parents couldn't figure out. The good ones turn into real apps that other people use too.

Dozens of apps. A few hundred little tools.
One very old cat, supervising.
The short version

For years I turned messy data into useful things for other people. These days I do it for myself — and for the people I love.

I'm not really an "ideas" person; I'm a finishing person. I notice the small friction everyone else has learned to live with, build the smallest thing that removes it, and actually ship it — domain, app store, the boring parts included. Then I sweat the details until it feels quiet and quick.

The doing is the point. Some of what I make is used by a lot of people; some helps exactly one person and a twenty-year-old cat. I care about both kinds — and I work the whole way, design through deploy.

“Every one of these started as a problem I had.”
— the only product strategy I've ever needed
What I make, and why

Almost everything I've built falls into one of these.

02 For the people I love

Family Helplive ↗
A big-text, no-login help page so my parents can fix the Apple TV themselves — written to be read over the phone. My favorite kind of software.
The small, quiet ones
A care plan for Oreo, my twenty-year-old cat. A little site for my dad, who's a drummer. Reminders that nudge me to call home before I'd otherwise forget. Not everything needs an audience.

03 For my city

The Islandtheisland.nyc ↗
A genuinely useful guide to Roosevelt Island, my neighborhood — transit, alerts, the things residents actually need. Building it now.
Subway Times · a weekly NYC digest · Good News
A live arrival board for my home station (because I got tired of opening Google Maps). A hand-curated note of what's worth doing this week — comedy, jazz, food, the quiet gems. And a calmer news feed, for the days the regular one is too much.

04 To make & to listen

Years of Spotify tools, beats at night, and trackers
Tools to understand my own listening, beats I make when it's late, and little watchers that tell me when a comedian I like drops a special or a jazz musician's playing tonight.

05 …and one because it was funny

Calculator Pro
The world's first AI-powered calculator. Results sold separately. Not everything needs a reason.
Off the clock

The stuff that doesn't show up in a portfolio — but explains the rest of it.

Where I'm at

Right now I'm betting on myself — building in the open, shipping something most weeks, and finding out whether "the person who makes small useful things" can be the whole job, and not just the nights-and-weekends version of it.

I'm open to the right thing: freelance, full-time, or a collaboration on something that matters. If you've got a real problem worth removing, that's my favorite kind of conversation.
