Who Am I?

My name is Sunil Shah, I am currently an Engineering Manager at Airbnb, where I manage the Service Orchestration team within Developer Productivity.

Prior to Airbnb, I was an Engineering Manager for the Compute Infrastructure team at Yelp, and an Engineering & Product Manager (and employee #21) at Mesosphere, a startup that was taking the Apache Mesos project to the wider world. I also previously worked in the Data Team at Last.fm and as a Graduate Analyst at Barclays Capital, both in London (where I'm from).

I am an alumnus of UC Berkeley, where I completed a Master's degree in EECS, and Fitzwilliam College, Cambridge, where I read Computer Science.

I am also an avid traveller. This site was my travel blog while I travelled through Africa and I've kept it spinning (no pun intended) since - as a resource to future riders and interested readers, and as my personal site.

Cycling

I started cycling seriously when I started sixth form, under the guidance of a friend who also cycled to school. At my peak I weighed 102 kilograms, in the summer of 2005 with a BMI that qualified as obese. When I matriculated, I joined the the Cambridge University Cycling Club and got involved in the cross country mountain bike aspect of the club and eventually became a committee member. In my time with the club, I took part in and finished 13 cross country races. After graduating, I was on the heavier side of 67 kilograms.

In 2010, I completed the Tour D'Afrique bicycle race from Cairo to Capetown, finishing 9th (out of 25 racers) and becoming the youngest EFIer to ride the tour. (My custom-built bicycle is described on the Bikes page. Andrew from Spanner.org.uk wrote a nice summary of the design behind it.)

In 2013, my good friend Phil and I embarked on a trip from Paris to Brindisi. We had originally planned to follow the audax route from Calais to Brindisi but time constraints pushed against us. All of my writings and photos from that trip are on this site and Phil's Tumblr can be found here.

In 2014, Phil, Armin and I cycled 475 miles down highway 1 from San Francisco to Santa Monica (effectively, Los Angeles). My photos from this trip are in the photos section and Phil's Tumblr is here.

In 2016, Phil and I entered the Cape Epic, known as one of the world's toughest mountain bike races. Phil was unfortunately hospitalised at the end of stage 3, and I completed the race as an individual finisher.

Unfortunately nowadays I don't spend as much time on my bicycle(s) as I used to. I am still, however, very much a Geek on a Bicycle!

Research

Real-time Image Processing on Low Cost Embedded Computers

This is the technical report I produced to fulfil my Master's degree requirements. In this project, we implement a vision-based landing system using open source libraries and then optimise it to run at the maximum framerate possible on an onboard embedded computer.

HTML Abstract, PDF (2.5MB)

We also published an article about this work, and a related project where we used machine learning to try and recognise abnormal motor operation, on the DIY Drones blog. 3D Robotics, our sponsor for the project, published an article on their blog about the growing drone community at UC Berkeley.

Social Bootstrapping: How Pinterest and Last.fm Social Communities Benefit by Borrowing Links from Facebook (WWW '14)

This was the second research paper I worked on in my 10% time at Last.fm in collaboration with Changtao Zhong, Mostafa Salehi, Marius Cobzarenco, Nishanth Sastry and Meeyoung Cha.

Distributed Twitter

This was the title of my final year project which resulted in a 11,337 word dissertation. While the project actually had very little to do with Twitter, it involved creating a routing algorithm to route hashtagged short messages between poorly connected mobile phones (also known as a Pocket Switched Network). It scored 79/100 against a class mean of 69 and was my highest scoring individual mark.

Computer Science - What to Expect

I go back to my secondary school often to help and motivate students who are interested in studying Computer Science. This is a presentation I gave at a careers evening which gives an overview of what studying Computer Science as an undergraduate entails.

East FM Radio Interview

On my way home from the Tour D'Afrique and shortly after climbing Mt. Kilimanjaro, I was interviewed by presenters Aleem and Seema on Nairobi's East FM about my trip. We didn't manage to capture the first part of the interview but the slightly more substantial second half has been transcoded from audio cassette to digital file.
