About

Hi, I’m Jiaxi (Jesse) Liu, a Master of Information Technology graduate from UNSW, currently looking for software, backend, and full-stack development opportunities.

I primarily work with TypeScript, JavaScript, and Python, with experience in third-party system integration, React interfaces, order-management APIs, web scraping, and automated testing. At Switchboard Cloud I worked on business-system integrations; at TidyTeddy I contributed to booking flows, order-management APIs, and crawler improvements. I also independently maintain this bilingual technical website.

I’m currently learning and experimenting with AI applications and agent development, focusing on tool calling, MCP, Agent Skills, and workflows. I aim to apply my API integration and automation experience to agent projects.

See my resume or get in touch about development opportunities.
