Based in Taiwan · Building worldwide

Ed Kung / Software Engineer

I turn fuzzy ideas into products people use.

Product-minded engineer working across mobile, web, and AI. I care about useful details, clean systems, and getting real things into real hands.

Small teams.
Useful products.

A mix of independent products and engineering work, built from first sketch to production release.

Decidex 就這吧

Stop overthinking. Just decide.

Decision-making app that helps you stop overthinking — five tools including smart shuffle, 10-second countdown mode, weighted random selection, dice and coin flips, with decision history tracking and dynamic color themes.

Engineering is a team sport.

01

Think in products

I start with the user tension, then shape the smallest useful thing worth shipping.

02

Build the system

From interface to infrastructure, I make pragmatic technical choices that hold up.

03

Create leverage

I automate the repetitive parts and improve the tools so the next release gets easier.

Current toolkit

TypeScript · Next.js · Flutter · Python · FastAPI · PostgreSQL · AI agents

Powder lines, slow travel, and very specific coffee ratios.

I'm Ed, a software engineer in Taiwan. When I'm not building, I'm usually chasing snow, getting lost in a new neighborhood, or dialing in a pour-over.
