I’m Ethan Wei, an AI researcher and software engineer with a strong foundation in quantitative finance and hands-on experience building production-ready systems in fintech. My work spans Bayesian optimisation for algorithmic trading, backend engineering in a Django REST Framework, and the design of robust, scalable pipelines that connect research workflows to real users and real products. Recently I've worked in developing and refining machine-learning-driven trading strategies, shaping optimisation frameworks, and engineering the infrastructure that supports them. Whether it’s reworking an optimisation loop, crafting objective-function logic, or shipping backend features in Python and Django, I focus on creating systems that are reliable, interpretable, and deployable. I thrive in collaborative environments, working closely with engineers, quants, and product teams to bring research ideas into production and ensure technical decisions directly support business goals.…I’m Ethan Wei, an AI researcher and software engineer with a strong foundation in quantitative finance and hands-on experience building production-ready systems in fintech.
