6 years in product development — from pre-Series B startups to enterprise clients in Indonesia, Hong Kong & South Korea. I ship web, mobile, and AI-powered products with Next.js, React Native, Python, and Golang.
I turn product ideas into working software.
With 6 years in product development, I've contributed to dynamic, fast-paced environments — including pre-Series B startups — and have successfully collaborated with clients from Indonesia, Hong Kong, and South Korea.
As a software engineer, I've delivered numerous projects with Next.js, React.js, React Native, Python, and Golang — including AI-powered products such as real-time AI chat streaming, AI-assisted document drafting and review, and a vision-model pipeline that validates location data against satellite imagery.
What I'm best at: turning fuzzy product asks into well-scoped engineering work, and helping the team around me ship without burning out.
