What I'm looking for

I'm looking for a remote software engineering role, preferably full-stack or product engineering. I enjoy working across frontend and backend, building products, and solving technical problems. I'm particularly interested in AI and developer tools, but open to different industries, technologies, and company sizes.

I'm a software engineer based in Jakarta, Indonesia, with 5+ years of experience across frontend, backend, and mobile development.

I spent most of my career at Shopee, building internal applications used by thousands of employees across 15+ countries. My work included building a 2FA backend service from scratch, improving API performance, and developing tools like MCP servers and VS Code extensions to make development easier. I've mainly worked with TypeScript, JavaScript, React, Vue, and Go.

Outside of work, I also build and publish my own apps. One of them, Oh My Bear, has reached over 1 million downloads on Google Play.

I'm interested in full-stack and product engineering roles, including opportunities in AI and developer tools. I'm open to different industries and technologies, and prefer remote work.
