Hello There

My name is Patrick Old.
I am a data scientist & software engineer
based in Portland, OR


More About Me

I discovered my passion for data science through research I did in oceanographic physics at the University of Washington. Since then, I have been working in industry and with research groups to use data science to solve problems. I am also a student in UC Berkeley's Master of Information and Data Science program.

What I Can Do For You

Data Science. Data Engineering. Software Development.
I am a technology generalist specializing in data science.

My Work Experience

August 2019 - Present


Data Science, Data Engineering, and Software Development
- Developed machine learning and artificial intelligence models using natural language processing and classification algorithms with Python, Pandas, TensorFlow, scikit-learn, and Jupyter Notebook.
- Developed numerous extract, transform, load (ETL) pipelines using Python, SQL, Airflow, Snowflake and AWS.
- Developed Flask web applications (Python, JavaScript) and deployed via AWS EC2 for implementation of production-grade machine learning models.
- Developed scripts in Java and Python for geospatial software and geospatial data science.

October 2015 - June 2019

University of Washington

Data Scientist - Climate Model Researcher

Led research analytics for a three and half year project to analyze variabilities and inconsistincies in the world's best climate models. Analysis was performed using Python. Work was funded by NASA and the NSF.

October 2018 - March 2019


Created two new undergraduate data science courses focusing on beginning and intermediate data science techniques in the field of oceanography. Courses were taught in Python, with a focus on the basics of numpy and pandas.

At the University of Washington I created and taught undergraduate
classes (Github) on how to create things like this.
Content included Python, numpy, matplotlib and more.

Now I use deep neural networks and machine learning to help bring ideas to life. Test out the following digit recognizer as an example (Github), which uses a convolutional neural network I built in Tensorflow (99.3% accurate on MNIST dataset). UI Credit: Benson Ruan

The Fascinating Truth of Studying Oceanography

Through my studies in oceanography at UW, I personally came to define oceanography as the study of the physical, biological, chemical, and geological factors of the ocean and how these components interact. And when you are talking about doing this with something that covers ~75% of the globe, it’s quite hard to do that by hand. Post.
