Employment
Experience
- Melanippe (Development)
A Cassandra profiling tool that was written in Python. It is a work in progress. Currently, all it does is give information about table configuration and schema. It's easier to use than cqlsh or NodeTool and, when finished, will have more useful features.
- FaceMatch (Development)
Built an authentication system using selfies and ID photos from users. The system uses machine learning to identify faces in images and then make a statistical comparison to determine whether or not the ID photo is the same person as in the submitted selfie.
- Risk vs. Reward: A Guide to Understanding Software Containers (Publication)Software delivery has come a long way. And, somewhere between the transition from physical media to software containers, we have changed the way we try to manage them. In this article, Toptal Freelance Software Engineer Jonathan Bethune explores how software containers have motivated us to treat servers as more dispensable, and the risks and rewards involved.
