Build useful things in public.
1% Better.dev is the public layer for my next season of work: small products, fast feedback loops, and visible execution that creates real signal for hiring, product, and future bets.
Built by Chris S. Yoon. Senior data engineer using this surface to keep shipping while the next role, product, and operating system take shape.
Role
Senior Data Engineer
Shipping small product loops while staying sharp on production systems.
Mode
Build in public
Use visible work to create signal instead of waiting for a perfect launch.
Focus
Useful first
Tight scope, fast feedback, and enough clarity to ship again tomorrow.
one percent, repeated
Small enough to ship. Strong enough to mean something.
The brand is not about motivational copy. It is about a working pace: keep the surface simple, ship the useful version first, and let repeated proof build trust over time.
Keep the product small enough to ship before it turns into a systems project.
Use this site as the public trust layer for hiring, product, and next-step conversations.
Let each new release earn more surface area instead of claiming it early.
Current thesis
1%
Improvement is a compounding operating system, not branding theater.
Useful
The first version should help someone before it tries to impress everyone.
Visible
Public proof matters because it shortens the distance between idea and trust.
Scope control
Keep poker as a separate specialist vertical until it earns more brand surface.
Use the landing page as a clean hiring, product, and credibility layer.
Let the operating system stay underneath the brand instead of dominating it.

Current products and public proof.
The front page stays focused on a few strong surfaces. Everything underneath still carries enough visible work to prove the pace is real.

Funding
Support the build. Buy more time for the next 1% better.
This site is not a product pre-sale page. It is a public build surface. If the work resonates, funding here is simply a way to help me keep shipping, keep learning, and keep buying focused time for the next loop.
Think encouragement, runway, and continued public reps. The poker-side funding lives on onepercentbetter.poker.
What support does
It gives me time to keep shipping while I look for the right role.
It covers tools, APIs, hosting, and the cost of moving quickly in public.
It keeps the simple products moving without turning the site into startup theater.
About
Chris S. Yoon
I spent the last decade building production data systems across fintech, media, and enterprise. Right now I am in a transition period: looking for the right next role while using 1% Better as a place to learn LLM workflows, ship simple products fast, and stay in motion.
Next step
Follow the thread before you reach out.
The cleanest path is: understand the story, see what I am building, then decide whether you want a conversation. That keeps the flow consistent with the rest of the site and gives the context first.
