A job search lives across five different tools that don’t talk to each other. So I made one that does.
It’s called HeffOS. One place for the whole thing: tracking roles, cold outreach, the materials you have to write, project management, and interview prep. All of it sharing the same context, so you’re never starting from scratch.
The thing I kept running into is how disconnected it all is. The role you’re tracking already knows enough to draft the outreach. The contact you saved already has what it needs for the email. The interview you’re prepping for is the one you’re actually applying to. That’s the entire point of HeffOS.
I designed the whole system end to end, the flows, the structure, the interaction model, and built it into a real, working app with Claude Code.
Blue means one thing here: the range you are looking at.
The value chart is a row of thin gray bars, and only the selected date range fills in blue. You read the period that matters and keep the months around it as context.
The phone carries the same chart above the holdings list. Each coin gets its own small bar chart between the name and the amount, so you can scan the whole portfolio for movement without opening a single coin.
Trading screens get busy fast. This one stays light and calm, so the numbers lead: total value, realized and unrealized P&L and open positions, all on one screen.
What if sending money felt a little more like giving a gift?
For Nova, I explored a banking app that brings payments, cards, and a bit of personality together. You can check your balance, browse recent transactions, send or request money, top up, and pay bills.
My favorite part is the digital postcard feature. Before sending a transfer, you can add a little illustrated card—a heart, a birthday greeting, or a playful character. A simple way to make birthday money or a thank-you feel more personal.
I carried that same 3D character into onboarding, pairing it with bold red gradients and large, clear payment details. There’s room for play, while the recipient and amount stay easy to check.
Would you add a postcard to a transfer? I’d love to know what occasion you’d use it for.
