I'm currently the COO of Capital Technologies, and spend most of my time working with the engineering and data science team, including IC'ing our analytics stack in python. We're putting together a great team to work on hard problems related to data architecture, financial modeling, ML, and building beautiful user interfaces.
In January 2019 I left the CTO job at Credijusto.com, Mexico City. By far the best part of my day-to-day in that role was the great team that I work with. A fun, ongoing technical challenge was finding a marriage between product development and data science.
I'm into bread and butter ML tools like random forests, xgboost, etc., but recently starting experimenting with deep learning for image recognition. You'll most often find me on here asking/answering questions about python or R, the two languages I write, and Airflow.
