Innovate. Implement. Impact.
Hi, I'm David Liu, a generalist software developer based near Seattle, WA with about 18 years of experience. I've built a variety of web, mobile, and data products from 0 -> 1 at companies both big and small. I've also re-architected complex applications, spun up new SDKs, and proactively made impactful enhancements boosting developer productivity and customer success metrics. I care deeply about fostering collaboration, technical excellence, and making customers happy. My recent experience leans more toward front-end and full stack web development, but I have the ability to learn quickly and make an impact on any product.
