Hello World!

I'm Rachel Sheikh, a Software Engineer striving to make the world a better place

Get in touch sheikhrachel97@gmail.com


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.
