NATHAN
HARING.

Some people have ideas.
I make mine work.

Native apps. Private systems. Tools that earn their place. Conceived, designed, and engineered by me.

Step inside the work

Don’t just look.
Put something to the test.

INTERACTIVE PROOF / 001LOCKER DROP
PLAINTEXT69 BYTES
SAMPLE / A SMALL MANIFESTO

Build things that deserve to exist. Make them work. Make them matter.

Nothing uploaded. Nothing to sign up for.
01

Make it unreadable.

Real encryption. Right here in your browser.

Sample content only · key stays in this tab · resets on reload

What this proves +

This is a real, local AES-256-GCM experiment using your browser’s Web Crypto API. Locker Drop uses libsodium’s XChaCha20-Poly1305 secretstream for file transfers. This smaller experiment demonstrates authenticated encryption—not Drop’s upload service, expiry, or a security audit. Only predefined samples are used; nothing is uploaded or saved.

Your computer
can do more.
AI is optional.

A native way to build local agents. Start with a trigger, choose what it may do, and look for evidence that it happened. Use AI when a step actually needs intelligence.

The SwiftUI prototype currently exposes file organization. Broader agent creation and external-agent connections are still being built.

03 / THE PERSON BEHIND THE WORKHUMAN, THROUGH AND THROUGH.

NATHAN HARING
BUILDER / FATHER / FIREFIGHTER

Calm under pressure.
Restless by nature.

I’m Nathan. A father, firefighter, and software engineer in Independence, Missouri. I build the things I wish existed—and take responsibility for how they work after they ship.

Family safety. A neighborhood marketplace. A graphics engine. Tools that help other people build. The problems change. The care doesn’t.

“The work has to hold up
when someone depends on it.”
PRINCIPLE / 01

Own the whole system.

The interface, the engine, the diagnostic pipeline. What happens underneath is part of the experience.

PRINCIPLE / 02

Make trust structural.

Privacy in the architecture. Safety margins in the math. Test the claim before putting it on the page.

PRINCIPLE / 03

Stay willing to be wrong.

A failed hypothesis is useful. A beautiful number from a broken test is not. Publish the limits, too.

SYSTEM TRACE

A few defining commits.

2018–2023

Learn to operate under pressure.

+

Volunteer firefighter and lieutenant at Perkasie Fire Company. Chief’s Award, 2022. The discipline behind the software starts here.

OCT 2025

Build the thing the family needs.

+

PayCheck Budget starts at the kitchen table. A real household constraint becomes a native app, Apple Watch companion, and a rule: do not call a purchase affordable if it leaves the family with nothing.

MAR 2026

A local idea reaches the city.

+

GoKC, a multilingual Kansas City guide, is featured by KCTV5 and Fox4 KC ahead of the World Cup.

2026

Build the engine. Question the instrument.

+

ScreenStage turns a custom Metal engine into a creative tool. prepass tests code retrieval against outside issues. The completion-gate study rejects its original hypothesis—and leads to plumb.
