Meaningful Milestone

October 29, 2015

Last night, Walkstarter, the school walkathon fundraising platform I created, achieved a meaningful milestone — $250,000 in aggregate funding for schools. This is so awesome. It’s also very exciting that more and more schools across the U.S. are requesting to use this platform. I have never really written much about the platform and this seems as good a time as any to give some background.


Three years ago, I managed to get elected to my kids’ school PTA and my assigned focus area was fundraising. Being completely clueless about how Walkathon fundraising works, I requested a meeting with the Walkathon Committee chair at the time. My goal was to understand how things work and what support she needed. I played it safe and told her I knew nothing, didn’t know what questions to ask, but wanted to support her in any way possible. She patiently explained how Walkathon fundraisers work and highlighted her two biggest challenges: (i) It took a long time to collect pledged funds, sometimes stretching into December, and (ii) It was hard for the Foundation to make plans without knowing how much money was going to be raised.

Very predictably, my brain gravitated towards an online solution. I drew inspiration from KickStarter, ran some ideas by the PTA, and thus, Walkstarter was born. Stevenson, my children’s school, used it for our Walkathons in 2013 and 2014, and despite my mediocre code, we saw stellar results. In the last few months, I have significantly enhanced the platform adding better funding page management, tons of analytics, processing for offline donations and a greater selection of avatars for kids to create including aliens and superheroes. (Screen shots at the end of this post).

Being a firm believer in “a rising tide lifts all boats,” as we got close to the end of last school year, with some help from others, I reached out to other Mountain View PTA leaders, and on May 18, 2015, I presented Walkstarter to them, and offered it as a 100% free solution for all Mountain View schools. They accepted and over the summer, I rewrote the platform to support any number of schools.

One month ago, just about the time Stevenson started its Walkathon fundraising, so did Bubb, Landels and Mistral, all Mountain View schools. After only a few days, other schools outside Mountain View learned about Walkstarter and wanted to use it as well. I obliged. Today, there are schools in Mountain View, San Francisco, San Jose and Orlando using Walkstarter, with other schools in the country in the pipeline. I think Walkstarter is gaining traction because it does one thing really well and is a simple solution to a very common problem. We are in an era of shrinking public investment in schools, and PTAs are being forced to pick up the slack.

“Parent fundraising has become more important as state and local funds have dwindled,” says Robert Reich, a former U.S. secretary of labor and now a political science professor at the University of California, Berkeley. “If we take the ideal of equal opportunity seriously,” Reich said, “we’ve got to commit ourselves to creating a system of public education in which kids from poor and working-class families have a genuinely equal opportunity to succeed. And we’re falling far short.”

Walkstarter is helping address the shortcoming. Given its primary capability of enabling fundraising outside of school localities, it affords schools, especially in poorer neighborhoods, an avenue to close the funding gap by leveraging non-local donors. On average, schools using Walkstarter are seeing 40% of funds coming from outside the local school area (example: I call this “trickle across funding” and think it is a very effective and efficient way for PTAs to achieve their funding goals.

My goal is to continue to offer and support Walkstarter at as many schools as possible. Wouldn’t it be great to reach the $2.5 million mark next year? I think it’ll happen. In addition to fundraising, I also see Walkstarter as a first step toward a vision of making free, high quality software tools available to all public schools, and look forward to having other like-minded folks join me on this journey.

Career Girls

November 2, 2014

A friend shared this delightful site recently:

If you have a daughter and want to help her see that she can be anything that she dreams of being, check out this site with her. You can see videos of women in many different jobs ( astronaut – check, physicist – check, executive – check … and many more). Yes, it’s sad that we even have to do this, but unfortunately there is too much marketing that our daughters experience daily that makes them think many things are only for men, and we have to relentlessly counter this when they are young.

Thanks Career Girls.

CoderDojo “Interactive Web” Session 5

May 21, 2014

After a whirlwind five weeks, last night was the last session of the CoderDojo “Interactive Web” series of classes. The sustained effort of developing the content for each class was exhausting, but it was all worth it; seeing the ~60 boys and girls see their browsers come alive with their own code was a joy to behold. I am not quite sure how (miracle, maybe?) that I managed to complete teaching all the material I had planned in these five weeks. We went from rudimentary knowledge of HTML to a fully functional, single page web app featuring Bootstrap, jQuery, Parse, OpenStreetMap, Leaflet and FontAwesome. The gist of the app is to present the user with a web form to which they can add some data including geolocation. This data is saved to Parse and then displayed on a map as interactive, animated markers.

You can see the finished app here Click the “Remix” button at top right to fork the code and create your own version of the app.



Code For India Hackathon

May 16, 2014

For the third time, my daughter and I teamed-up for a Hackathon. This time it was at Google for the “Code For India” Hackathon. The goal of the Hackathon was to create solutions to solve challenges related to problems in India. We picked the challenge related to advancing financial literacy for kids through gamification. Our solution called “Kaisa Paisa” (means “how money”) is a game plus simulator. You can check it out here:

Since the Hackathon ran late, we didn’t stay till the end. Today, I was at the TieCon and happened to see a story about the Hackathon on the front page of the IndiaWest newspaper. Imagine my surprise when I saw this paragraph in the story:

Teams competed for several prizes donated by Google and Intel. The “most popular” project – Kaisa Paisa, an app for AIF that allows kids to develop financial street-smarts through games – was developed by Nik Kalyani and nine-year-old Gia Kalyani. The father-daughter team received a Moto G smartphone for developing the winning application.

How exciting!

CoderDojo “Interactive Web” Session 1

April 23, 2014

Yesterday was the first session of a new series I am teaching. Organized by CoderDojo, the session was geared towards kids who have prior HTML experience. Through the series, I am going to introduce kids to interactive web development and Cloud services. We had the session at Microsoft’s Silicon Valley Campus and had a full-house. My daughter Gia was a co-presenter.

In this session, I introduced the kids to CSS and added a fun design element. They had to create their own Mondrian art, using CSS.

Here are some stats on attendance:

Ages – how many attending

  • 9 years old – 12
  • 10 years old  – 8
  • 11 years old – 14
  • 12 years old -12
  • 13 years old – 8
  • 14 years old – 4

29 boys 27 girls

Experience with HTML

Hours – how many attending

  • 1-10 hours  – 23 ( but should have had previous web class)

Mojio-Hertz Hackathon

April 6, 2014

My daughter and I teamed-up at the Mojio/Hertz Hackathon at NestGSV Silicon Valley yesterday. Our app — GoodGaadi — was the winner of the Social category. It uses real-time telematics to aggregate driving data to the Cloud. It then scores the data and enables individuals to have a safer driving competition with friends, family and colleagues. It’s the gamification of safer driving!

Winning was very exciting, especially for my daughter. This was her second hackathon and so far she has won a prize in both. This time, the prize included an XBox One, $500, Mojio devices and of course, bragging rights.


Mojio’s technology and API inspired us to build this app. It has never before been possible to aggregate real-time data from multiple vehicles on the Cloud. The Mojio device is a small cellular device that plugs into the port of any car manufactured since 1996 and streams real-time data about your car to the cloud over the cellular network. (Learn more here — )

But our motivation came from elsewhere. Each year, over 30,000 people die in automobile accidents in the U.S. Countless others get injured. The cost to our economy is over $150 billion annually. We can change this. If each person makes small changes and eliminates bad driving habits such as hard braking, sudden acceleration, hard turns, excessive speed etc., over time, our roads will get safer and fewer people will get injured or die. Driverless cars will help, but for the foreseeable future, there will continue to be human drivers and making roads safer will continue to be a challenge.

We are looking forward to working with Mojio to bring GoodGaadi to life. Tell us your thoughts on safer roads and safer driving and our approach to this problem.

Microsoft Big Data Hackathon

February 9, 2014

My daughter made her hackathon debut at Microsoft’s “Big Data Hackathon” yesterday+today. We used San Francisco parking meter data, map-reduced it with Hadoop and created Meterzilla — a site that helps you identify parking meters that are within walking distance of your destination (based on how many minutes you are willing to walk).

It was fun having my daughter as my team-mate. The best part — we won first place! 


Facebook/Parse Mobile Hackathon

November 14, 2013

My team’s app “HiveHere” won third place at the Facebook/Parse Mobile Dev Day Hackathon. Wooohoooo!!!

HiveHere is an app that uses Bluetooth Low-energy to automatically match persons with similar interests at a conference.


SVCC Talk: Real-world AngularJS
