Jae Li

I am a software engineer with a keen interest in developing scalable systems, especially in the domain of web technologies and AI. I like making things that facilitate gathering and create a sense of community. I recently completed my tenure at Zafin, where I led the development of a query engine to enable embedded analytics for banking systems. Prior to Zafin, I worked at Signiant, where I built enterprise applications for file transferring. Beyond coding, I am active in the local tech scene. You can find me in tech events and meetups in town. I am based in Ottawa, Canada.

Work Experience

    Zafin — 2023.9-2024.6

    At Zafin, I led the development of a core middleware across two teams of cross-functional teams. The middleware leveraged a query engine to make analytics dashboards for enterprise banking systems. I was responsible for the design and implementation of the middleware with the existing product, ensuring its performance and scalability through k8s design patterns and extensive testing. The success of the project led to the adoption of the same architecture in another team.

    Signiant — 2023.5-2023.8

    My work at Signiant involved fullstack development of its cloud native application. I implementation admin features for managing and monitoring the file transfers. I use Test Driven Development (TDD) to ensure the quality of the code, shipping features with 95% code coverage.

    University of Ottawa — 2022.8-2023.8

    A significant proportion of my time during my master's degree at uOttawa was spent on building robotics. I worked as a research assistant to develop an ethics of AI course, where I hacked robots to simulate ethical dilemmas in human-robot interaction. I was also a member of the uOttawa Mars Rover team, where I developed robotics navigation and camera systems.
