Suttisak Denduangchaiสุทธิศักดิ์ เด่นดวงใจ
I build useful systems where medicine meets software.
I work at the intersection of occupational medicine, data, and software, turning complicated clinical workflows into tools people can actually use.

Japan, observed
Photography gives me a slower way to study systems: streets, rituals, signs, light, and the small decisions that make a place feel coherent.
Medicine, systems, and the work between them
I'm an Occupational Medicine physician and software developer. Most of my projects begin with a familiar clinical problem: information scattered across spreadsheets, repetitive work that steals time from people, or a process that was never designed as a system. I study the workflow, build the missing tool, and keep refining it alongside the people who use it.
The goal is not software for its own sake. It is calmer work, clearer decisions, and better care.

Useful systems begin with a real problem.
I am interested in work where clinical knowledge, thoughtful product design, and practical engineering can make everyday work clearer and more humane.
