Feel free to reach out to me at bhalla.kunal@gmail.com: I must warn
you that I'm remarkably bad at replying to email.

The latest incarnation of this site was rendered using org-mode’s
project publishing support.

You should check out the rendering configuration here — it’s
interesting enough to write a note about at some point. You’ll also be
interested in the source links in the footers throughout the site.

** Career
I'm a Software Engineer at Facebook New York working on developer
tools for data and ML engineers. You can find me around the internet on
Facebook, Instagram and Twitter. [fn:links]

*** October 2019 - present: Developer Infrastructure
I'm now working on infrastructure that powers tools for AI and Data
developers at Facebook; moving back to server side development after a
5 year stint on Android.

I spend my days playing with python and working with -- and stretching
the limits of -- python notebooks.

*** July 2016 - October 2019: Android Battery
Going back into systems, I worked on instrumenting and understanding
Facebook's battery consumption and setting up systems to keep battery
consumption within reasonable limits. We worked on getting these
systems set up across Facebook's family of Android apps.

We've talked publicly about this work -- at Droidcon SF and
Mobile@Scale, and also open sourced the core library for
instrumentation: Battery Metrics.

I also spent a significant amount of time working on underlying
infrastructure in Facebook for Android to make it consume less
resources without affecting behavior.

*** July 2015 - July 2016: Android Checkins
I was curious about what user-facing product work was like after
spending almost 4 years working on very different layers of

We worked on testing out new types of stories for checkins, where I
was leading the Android engineering team.

*** July 2014 - July 2015: Android Maps
After working on mobile stack traces without actually understanding
how mobile development worked, I was very curious about how Android
worked and learned Android at Facebook.

I had a chance to work on a tiny maps client that allowed scrolling,
panning, interacting with maps, drawing geodesics, etc.

I have 2 patents from this work: fast caching/ rendering as well as
rendering multiple sources.

*** 2013 - July 2014: Mobile Reliability
This was around Facebook's transition to mobile: we have tools that
aggregate stack traces to allow actually understanding what's broken
and how badly it's broken.

I worked on converting the tool to work properly for mobile: new ways
to categorize traces as well as setting up the infrastructure to scale
with new error sources.

*** 2012 - 2013: Web Reliability
I worked on tools that measured how many errors Facebook's
web-endpoints were having. A lot of visualization, PHP, Javascript and
a smattering of C++.

I'm most proud of a pipeline rewrite that allowed us to get
information about the status of www.facebook.com in 30 seconds instead
of the earlier 15 minutes.

[fn:links] and even Linked-In, and Quora.

** Education
In a past life I studied Civil Engineering at IIT Delhi from 2007
— 2011, with a minor degree in Computer Science.

I also interned at Yahoo Bangalore, Peri, Foodiebay (now known as
Zomato) and some other startups; apart from taking part in Google
Summer of Code 2010.
