AI Expert & Fractional CTO
From coding at 9 to transforming enterprises with AI—the complete journey of building the future, one algorithm at a time.
Early Life & Education
My journey with technology began at age 9 when I wrote my first line of code. It was in a language called Logo, popularly known for the turtle that could be instructed to draw fun graphics. I don't remember too much about this time in my life, but I do remember that there was some unspoken excitement and satisfaction in getting the turtle to draw what you needed it to draw.

I've been found of computers for as long as I can remember. It was an innate response. They drew me in.
My parents did a tremendous job though they might not realize it or claim any credit. My father would always say "He should become comfortable with tech." Now that I think back to my early years, I vividly recall that my parents were extremely supportive of my crude experimentation. I'd always wanted to know how things worked. Like taking apart a tape recorder, or standing around watching a computer repair person disassemble and work on a PC. Somehow, systematically, my parents and the environment they created, made me truly curious.
In 2004, at school, they taught us BASIC. I was thrilled to "talk" to a computer. It did what you asked it to do! You just had to learn how to talk to it. We uses to use QBasic IDE. My first ever IDE. The interface was white on blue. And it was fabulous.

I was never a "good" student. My grades were always average. My parents tolerated this, as much as Indian parents can. But I was good at computers. I understood computers, and more importantly, computers understood me.
Back then, my father used to work in R&D at IBM. He had this gorgeous black laptop, with a red dot in the middle of the keyboard. An IBM ThinkPad (this was before Lenovo bought the ThinkPad PC division from IBM). Talk about love at first sight.
There was something about this machine. The subtle beauty of its design. The fact that it packed so much power in such a small package. I dreamt about that laptop.
Funnily, this was back in a time and age when we'd regularly buy computer magazines like Chip and PCWorld. I'd read them cover to cover. Not necessarily going into the depth of any one article, but skimming through things, stopping and reading more thouroughly whenever something caught my attention. These magazines had great ads for different kinds of computers. That was probably the first time I came across the term "server". IBM and later, HP, use to list servers for sale in these magazines. The best thing about computer magazines was the CD they'd come with. These CDs had games, utilities and more!
I had a humble PC when I was growing up. A custom build. If I recall correctly, it was a Dell machine that my parents purchased in the US. But its motherboard went bad so we had to replace it with a Mercury motherboard. Eventually, the CPU case was replaced as well, but the original Dell CRT monitor worked great. This beast of a machine would plug into a hefty UPS that would plug into an AC socket. I believe the specs were something like 256MB RAM and 20GB HDD. It had a CD ROM drive and a floppy drive. Later, the CD ROM drive was replaced with a DVD drive.
Those were fun times! We'd have some assignments at school that could be done as PowerPoints. I'd come home, excited to have an excuse to use the computer, and work on a PPT like a sad MBA student. The only difference was, I was in 8th grade. We'd then write these files to a 3.5" 1.4MB floppy disk and take it to school. Floppies were so fun. They had this "shutter" that you could use as a fidget toy! The only problem was, that since floppies used magnetic particles, they were quite succeptible to corruption! So many a time, you'd make a backup and pray that at least one copy survived. Little did I know that this was an early introduction to disaster recovery and management.

I hated computer theory but couldn't wait for labs. Because that's when we'd get to use computers! I wanted to be around computers ALL.. THE.. TIME. I was notorious during my schooling years. I learned about Windows' shutdown -i
command and would turn off all computers on my network. Padma ma'am and Vasudha ma'am tolerated my discretions. They were stern, but didn't reprimand me too much. They would always know it was me, but I was quick.
Why I was quick, was because my father had the brilliant idea to teach me proper typing early. He decided that since keyboards are such an important input to computers, I should wield it well, and correctly. Not for speed, but for efficiency. We were traveling to my mother's native town called Gudur, in Andhra Pradesh. I believe it was my aunt's wedding. We were put up in a nice guest house! I thought I'd have a lot of fun, and I was very excited for my aunt, but my dad had other plans. He had installed this software called KiddyType or something like that on his ThinkPad, and made me learn and practice typing. For every mistake, it would say "uh oh" in such an interesting way. That sound is forever burned into my memory.
I think it was the summer of 2006 (I wish it were '69). My parents said they had some urgent and important work, and left me at Rama aunty's house. Rama aunty and her husband, Suryodhayam uncle were my local grandparents. Because my real grandparents all lived so far away. My local grandparents on the other hand, used to live in our society in Bangalore and were the loveliest of people. That day, Rama aunty made an incredible veg pulao paired with a cold vegetable raita. She even gave me some Amul butterscotch ice-cream. Including a second serving! That evening, my parents returned with a surprise. Probably the biggest surprise of my life that far. They had bought a laptop for me. An Acer machine with 1GB RAM and 40GB HDD! It had some Intel chip but was one of the best laptops at that time.
Being a child, I was thrilled, because in my mind, I was thinking "This can run Midtown Madness!" But my dad had a rule. No games! He bought and installed Encyclopedia Britannica on my laptop. Back in 2006, you had to have like 15 read-only DVDs to install the entirety of Britannica. But it was great. The Internet wasn't as commonplace, so there wasn't too much to do on a computer for little kids. Britannica was like my own local copy of Wikipedia. I would spend hours on that thing. Reading about everything I could think of, and using interlinks to go other encycopedia pages to read some more. I would read about jet engines, about mummies, about art, and about so much more. I remember having some kind of children's encyclopedia. Physical books! 5 or so volumes. Thin, with great pages and tons of illustrations! I first came across ideas of astronomy and was introduced to black holes through this set. And then, the digital Britannica on my laptop took it to the next level.
Soon, due to some personal reasons, I would have to yield my laptop to my dad. But I'd get another one, a much more powerful one soon after! Probably the summer of 2007 or so. It was again an Acer. But it was Core 2 Duo (dual processors). A beast of a machine. This laptop was truly my own. And I squeezed it to the maximum.
In 8th grade, my school friend, Kshitij, one of the brightest boys in my class brought a Rubick's cube to school. We had a 3x3 Rubick's cube lying around the house since I was little. I never knew how it worked. I always thought it was a toy that would roll really funny and didn't think it had any purpose. I vaguely remember my father telling me there's a bunch of math involve with making it work. I didn't like math very much, but I was fond of rolling the cube around the house.
Now, Kshitij brought this Funskool 3x3 cube to school. And this little bugger could solve it! That was the first time I saw what a Rubick's cube could do. I didn't know there was a trick, so I tried his cube to see if I could do it intuitively. Most people can probably solve one side intuitively given enough trial and error. But beyond that, its improbable to use intuition. I was thrown off. You think you're solving it, but you're ruining the solve side at the same time. I didn't know there was a trick. I begged him to teach me. He did! He taught a lot of people at school. Kshitij taught me the beginners solution. Or at least he tried. He wrote a bunch of algos down and explained how to do it. We were at our school's annual day event. There was some band of uncles performing some kind of rock music. I didn't care. Kshitij was teaching me how to solve the Rubick's cube.

Fig: Funskool 3x3 Rubick's cube
I think I was able to do it once, in front of him. Because he kept giving me feedback whenever I was messing up. I begged my mom to buy me a Rubick's cube. She was always on my side. She obliged. We went to a store a few blocks away from our society and my mom bought me a Funskool cube. It was the gold standard back then. You had to lubricate it yourself with some coconut oil or some vaseline, as Kshitij would later teach me, and that's what made it a speedcube.
The problem though, was that once I got my own cube, I couldn't for the life of me figure out how to solve it. Even though I had the piece of paper from Kshitij with the algorithms. So I had to do a forbidden thing. I hooked up my home phone's RJ11 jack to my trusty Acer laptop and connected to the internet via dialup. I searched for information on solving the Rubick's cube. Lo and behond, I come across this site called YouTube. Huh, what a funny name. And it promised a video tutorial. But the problem was, this was a ~56Kbps line. Yes, kilobits. Which means that it took forever for the video to load. But it did, and I learned how to solve the cube. Then I swiftly disconnected and plugged the cable back into the phone. My parents would received a hefty phone bill at the end of that month. And my dad would blame it on my mom. I couldn't snitch myself out. I wasn't really afraid of a beating, but I was definitely afraid of my parents taking away my laptop (which they would probably never do, btw). Sorry, Maa!
And here, my own personal unsupervised journey into the infinite world wide web begins. But I had to find a solution for accessing the Internet. I could no longer sneak the phone line into my laptop. That's super obvious. So whenever I was able to connect via dialup, I would look for ways to get free Internet! I came across some articles about people that used some toy whistle from a cereal box to do this, but they didn't have Cap'n crunch in India. I remembered this technology called Wi-Fi that I heard about. I thought I should try my luck and look for WiFis. And to my luck, I found one. Srikanth uncle from upstairs, Aditya's dad, had WiFi. And it wasn't protected. The best part? I would mostly always get a great signal from my own bedroom because it was right next to the window. Bless whatever router they were using because my laptop was at least 20 meters away, diagonally, in 3D space, since we were on the 2nd floor, and the Vachaspati's were on the 3rd.
I dabbled with programming. During my 7th grade summer break, my parents put me through Java training at NIIT Hyderabad. I was familiar with the core concepts because my dad bought me Head First Java and then helped me set everything up on my beloved Acer Aspire Core 2 Duo. I think my second IDE, after QBasic, was Eclipse. My dad had also set up Netbeans. But really, IDEs were quite overwhelming to me. I spent a lot of time writing code on Notepad and compiling with javac
on the Command Prompt. At NIIT, I was the youngest in my class. A 7th grader, going to 8th grade, and learning Java. What's funnier perhaps, is that I was ahead of my class.

I was already able to make complex GUIs from the examples in Head First Java. I really enjoyed GUIs for some reason. Though they were really clunky to make at that time. The infamous Java language entrypoint method, i.e. public static void main(String[] args)
seemed like a cheatcode. Like the algorithms I had learned earlier to solve the Rubick's cube. Great for impressing people, but I know it's just a trick. I wanted to go deeper.

Fig: Head First Java
I wanted to understand networking, I wanted to understand RMI, I wanted to understand EJB, and Applets, and Servlets, and J2ME. But it was too much for an about-to-be 8th grader. At least, it was too much for me.
Overconfident with passing the NIIT test with flying colors, I thought I could take on the SCJP. My dad told me that there's a question bank and the right way to prepare was to learn the question bank. I didn't like this idea. I didn't want to cheat. And so, I gave the SCJP in the 8th grade. Without studying the question bank. Like an idiot. My mum sneaked me to the test, against my dad's wishes. She believed in me. But I failed. Miserably. This failure was personal, because I felt like I had failed my mom. This failure would not only haunt, but also humble me for a while. (In retrospect, maybe it was a good thing?)
I realise I've missed out on some things. In 6th grade probably, I had a good friend and classmate called Satvik. An albino boy. His dad was into etching pens and selling them to businesses. As far as I remember, he was the first person to introduce me to the idea of hacking. I think I took that futher by finding information from books at my school's library and then some more on the Internet. That's how I found out about interactive shutdown on Windows.
Another thing I missed is before my parents got me involved with Java, my dad had a quick visit to Canada on some business. I believe he was going to attend some PMP conference there. On his way back, however, he did the most insane thing. He took an expensive cab to some remote place in the outskirts of Canada to buy a LEGO Mindstorms NXT 2.0 kit for me! And he had them ship it to India. This kit was so much fun. Apart from the standard LEGO building blocks, this kit came with a programmable "brick" that could interact with different elements like servo motors, different kinds of sensors, and more! I tried every single one of the projects in the booklet, including building my very own humanoid robot with it. I don't think I did the kit much justice, but it certainly got me thinking about programming and engineering because you had to write code to make it work. This was ahead of its time and was probably the first no-code low-code capabilities I ever used.
