Full-Stack Data Science


Welcome and Introduction

Hi!

I'm a Data Scientist based in Kenya 🇰🇪, from the USA 🇺🇸.

Check out some of my projects, and let me know what you think at my email or social media accounts below.

I finished my Masters in Economics in 2013, followed by a long hiatus as a parent raising my daughter through 1st grade.

Since 2013 I have been doing service projects partnering with daycares in Kenya and Rwanda to help kids learn to read earlier.



rongzi

Rongzi finds optimal network paths connecting Chinese characters based on a character decomposition database.

show/hide more details

Users may find meaning in paths between adjacent characters in names or proverbs etc.

Many Chinese characters are composed of sub-components which may contribute meaning to the larger character. For instance, 好 is composed of 女 (woman) and 子 (child). These composition/decomposition relationships form a graph network.

Rongzi finds these paths by recursively querying a Chinese Character Decomposition database.

Completed April 2022



predwikt

Predwikt implements a time-series prediction (historical backtracing) of Wikipedia edits.

show/hide more details

For each "current" date, predicts "today's" edit count for a category of articles based on past edit counts and the calendar.

Cross-section and historical data for the Japanese-language Wikipedia were downloaded as .sql and .tsv files. Data prep in MariaDB was managed from a Jupyter IPython notebook via the mysql.connector API (SQLAlchemy).



tunasoma

Prototype of a wearable app leveraging speech-to-text for earlier toddler reading.

show/hide more details

I conceived the original application, and wrote a specification for a simplistic proof-of-concept MVP. I developed a backend with Google Sheets, Apps Script, and Firebase, and hired a Flutter freelancer on Upwork for the front-end and Google Cloud Speech API interface.



Early Reading

Early Reading programs in Kenya and Rwanda.
(Economic Development project, not data science.)

I recently began collaborating with a daycare in Nairobi/Ruiru that is helping toddlers learn to read with unforced flashcard-play.

I have also been collaborating since 2013 with a youth group in Rwanda (YADE / Youth in Action for Development, contact: Elisee) in early reading. Since then, YADE has founded the Malaika nursery and primary school.
