Python 90%
Scala 70%
Spark 70%
AWS 75%
Machine Learning 80%


Retaining in-house talent can be a time-consuming and costly endeavor. Training, turnover, and payroll taxes always threaten to eat into your bottom line. Why not hit the ground running and contract your work out instead? Here are a few of the services I offer:

Operational Automation

Automate reports, data feeds, dashboards and more to be delivered by email when needed


Build a website that's every bit as unique as you are, and host it on AWS for greater backend control


Develop your own custom APIs in the cloud to deliver mission-critical information in real time

Data Analysis

Find the signal within the noise by consulting with a dedicated, experienced data analyst

Machine Learning

Create machine learning algorithms and AI bots to identify patterns that are invisible to the naked eye

Data Lake

Unleash the power of parallelized computing with the help of HDFS and Spark
