Decide is an ad platform that uses machine learning and AI to optimize returns from advertisements for both brands and publishers.As a Machine Learning Engineer, I design, evaluate, and deploy models that maximize the revenue Decide generates for its brand and publisher partners. My models combine modern machine learning tools with decision making processes rooted in core business goals, giving them the power and stability necessary to succeed in production.I also develop many aspects of our machine learning environment, including data import and cleaning, codebase management, model specification, and performance monitoring. Highlights:* Increased performance for a top publisher with a model that aggregates historical data to reduce variance.* Deployed an Autoencoders to identify performant ads in segments with few clicks and conversions.* Introduced new metrics to support modeling for programmatic placements (i.e., where Decide must compete in an auction to show an ad).* Built tools that simplify the process of evaluating TensorFlow models' performance before going into production* Accelerated the development of the ETL pipeline that Decide uses to get data from BigQuery and third-party APIs into our machine learning environment.* Wrote scripts that automate dependency management and style checking for Decide's R and Python codebases.* Voted team MVP by colleagues for Q4 2021-Q1 2022.Tools: TensorFlow, Python, R, SQL, GCP, git, Docker, Airflow, Bash, Scikit-Learn, XGBoostMethodologies: Machine Learning, Statistics & Probability, AI, Data Visualization, Object-Oriented Programming, Functional Programming, Unit-Testing

I am responsible for designing and implementing quantitative research projects on immigration, public policy, and political behavior. I have worked closely with stakeholders to translate research into policy with real-world impacts.Highlights:* Developed a partnership with the City of Zurich based on using data science to expand their immigrant outreach efforts.* Implemented a randomized control trial to understand effects of letter campaigns on naturalization* Analyzed large administrative data sets with causal inference and machine learning techniques over the cloud* Managed complex survey projects through design, data collection, analysis, and reporting* Produced outputs including scientific publications, policy briefs, presentations and media coverage of my research

Zurich, Switzerland

I taught masters-level courses in data science. For these courses, I designed and lead tutorials introducing students to coding in R, statistics and probability, and causal inference with experimental and observational data.
