Data Engineer Data Scientist
I build data platforms and analyze data for a living, with a focus on machine learning and causal inference. On my days off, I play folklore, the folk music of the South American Andes.
About
My work is about collecting data, putting it in order, and making it usable. I move back and forth between building the platform and doing the analysis, and I care about seeing things through, until an initiative is actually running and its effect can be seen.
After graduate school in physics, I started out as an engineer on an ad delivery platform and later moved into data science. Today, alongside building data platforms and doing analysis, I work with companies from the earliest stages to think through how they can put their data to use.
Outside of work, I belong to two groups, Nishida Friends and YAMA, and mostly play original music influenced by folklore.
Work
-
Data platform design and engineering
I build platforms that bring data scattered across businesses and services into one place, shaped so it is ready for analysis and new initiatives. I take the work from requirements through implementation, and aim for systems that stay in use, including access control and the handling of sensitive data.
-
Data analysis and machine learning
I use exploratory analysis to find problems, propose initiatives, and measure their impact with A/B tests and causal inference. I also build machine learning models for customer scoring, churn prediction, recommendations, and more, and take them all the way into production.
-
Data strategy consulting
I get involved from the very beginning, sorting out which data will be used, by whom, and for what. As a project lead or manager, I drive work such as planning company-wide data platforms, preparing requirements for vendor selection, rethinking business processes around data, and designing business KPIs.
-
Application development
I have worked on software that brings data and analysis into real services, including high-traffic ad delivery systems, the recommendation APIs that run on them, and internal tools powered by generative AI. I work across the stack, from frontend and backend to cloud infrastructure.
