Clarity over cleverness
Simple systems that the next engineer can read beat clever ones only the author understands.
About
A small studio that ships
We are engineers and designers who got tired of watching good ideas die in handovers, so we built a studio where strategy, design, and engineering sit at the same table.
Who we are
Built by people who still write the code
TDH Software is a digital agency and product studio. We work with founders, product teams, and established businesses to turn ideas into software that holds up under real users.
We are deliberately small. That means the person who scopes your project is the person who builds it, and decisions do not travel through three layers of management before reaching a keyboard.
Alongside client work we run KoiSpeak, our own Chinese learning platform. It is where we test our standards on ourselves first: performance, accessibility, support, and the discipline of saying no to features.
What we value
Four things we refuse to trade away
Honest timelines
We give estimates we believe, flag slippage the week it happens, and never hide bad news until the deadline.
Craft in the details
Loading states, empty states, error messages, keyboard access. The parts users notice only when they are missing.
Long-term thinking
We build what will still make sense in two years, not what is fastest to demo on Friday.
How we operate
The working agreement
Send us the problem you are trying to solve. If we are not the right studio for it, we will say so and point you somewhere better.
-
Weekly demos
Every week you see working software, not a status report. Progress is something you can click.
-
One shared channel
Direct access to the team in a shared workspace. No ticket queue between you and an answer.
-
Documented decisions
Architecture choices and trade-offs are written down, so the reasoning survives after the project ends.
-
Clean handover
Repositories, infrastructure, credentials, and documentation transferred properly, whether or not we stay on.
