Experienced the entire workflow including machine learning researches, developments and deliveries to real customers as a software engineer and a data scientist. The core skills are Python/PHP/Javascript/Java/SQL/Cloud/Agile and anything related to machine learning. Handled various types of data, equity trading data, hotel pricing data, company revenue forecasts, time series data, blockchain data, social game data etc. Worked in a technology research team in a US based investment bank as a new grad, and moved to a hotel startup to challenge more difficult business problems as a technologist. Since data analyses result never be utilized only in a research team, data visualizations for non-scientists is also one of my areas. Created data analysis pipelines including data collections, data analyses and data visualizations with cloud and BI tools. Occasionally joined client facing teams to help them to make decisions based on the data. Worked for a blockchain startup as a data analysis lead. Responsible for anything related to data analysis including marketings, growth hackings, customer supports and meetings with investors. Currently being self-employed and helping some clients to utilize their data and mobile and web developments.

Senior Data ScientistOyo Oct 2019 - Apr 2020Tokyo, Japan1. I was in charge of the dynamic pricing for hotels as a data scientist in the revenue team. The team was ten people and we were expected to come up with the best algorithm for optimizing occupancy rates and hotel prices. We did the analysis with Python and the latest machine learning methods for the optimization.2. We visualized all the analyses results on dashboards and helped the client facing sections to understand the data easily. We utilized Metabase, one of the popular BI tools, for the visualization.3. I was leading the project of the company revenue forecast, which was aiming to forecast the revenue beyond three months. I have created the XGboost based forecast model with the limited amount of data. The model successfully forecasted the company revenue with only the several thousands JPY difference accuracy.4. I was also occasionally working in the sales team to help the sales team head to decide the sales strategy based on the data analysis. -
