Direct
Speak with the developer doing the work, not layers of account management.
About me
Independent thinking.
Accountable delivery.
I work independently with organisations that value direct communication, thoughtful engineering, and software that earns its place in the business.
Why work with me
Technology is only useful when it improves the work around it.
Good software is not measured by the number of frameworks, screens, or features it contains. It is measured by how clearly it solves a real problem, how confidently people can use it, and how safely the business can depend on it.
That principle guides every engagement. I ask direct questions, make trade-offs visible, and choose technology for the product rather than forcing the product into a preferred stack.
Independent by design
I’m YiKai Tang, a full-stack software developer working directly with clients across discovery, implementation, deployment, and handover. YK is my personal brand—not a company or agency—so technical judgement stays close to the business need and accountability remains clear.
Global by default
I work remotely with clients worldwide. Clear written decisions, visible progress, and practical handover make collaboration effective across time zones.
Ownership without dependency
You receive the agreed source code, documentation, and deployment knowledge. The goal is a useful long-term asset—not a system that only its original developer can understand.
Working principles
What you can expect.
The best client relationships are built on shared clarity: what we are solving, what has changed, what is at risk, and what happens next.
Practical
Prefer clear, maintainable solutions over fashionable complexity.
Transparent
Make scope, decisions, progress, and risks visible throughout.
Responsible
Build with security, reliability, and long-term ownership in mind.
