Background

I am currently working as a TL on the Live Services team at Twitter. Through this team, I work on a variety of live streaming services and projects for the Twitter platform, check out this Tweet to see what I've launched in the last year with the help of my team!

I am also a Teaching Engineer at Interviewing.io, where I mentor and foster engineering talent for cohorts of early-career engineers, teaching them Go and AWS, as well as engineering best practices.

I am also an interviewer at Onramp.io, where I mentor and host mock technical interviews for engineers at all levels, in order to empower them to progress further towards their career goals.

Finally, I am also the Head of Engineering at Dora. In this role, I help to hire and grow the engineering team across the company, I lead development on the API and Data layer teams, and I work with engineering leads across workstreams to define our technical and product roadmaps.

I largely align myself with backend engineering, and my languages of choice are Go and Python. I am extremely interested in projects relating to video/media streaming, distributed systems, and cloud technologies.

Previously, I led engineering efforts within State Farm's RED Labs, where we built out an Alexa/mobile-based experience to connect seniors with their community of friends and loved ones, and launched it under the name Sundial. Before that, I was a software engineer at Microsoft, Telos Corporation, The Discovery Channel, and Volkswagen Credit, Inc.

When I'm not working on professional projects, I enjoy watching new movies/tv shows, going hiking, cooking new recipes, and playing video games.

Building a tool in Python to enable developers to provide users with higher availability by implementing chaos engineering through simulated cloud failures and by presenting a rapid fallback mechanism to rotate traffic over to unaffected cloud platforms. Also integrating support for custom predictive fault models to determine when unused cloud resources should be spun up to be ready to handle incoming traffic rather than causing downtime during traffic transitions.

Chord is a Firebase-integrated web application for musicians that makes it easy to record practice sessions and leave feedback at a particular timestamp in the audio for review at a later time. This was made with two other developers in roughly 4 hours. I might revisit the project some day to package it for mobile and flush it out.
