Karthikeyan Govindan

கார்த்திகேயன் கோவிந்தன் is the founder and lead engineer of Lakecipher, working on web, mobile and blockchain software and on smart contract security, from Mayiladuthurai, Tamil Nadu.

In my own words

I've been connected to Mayiladuthurai for more than 23 years. It's home, and it's where I decided to start this company, rather than in Chennai or Bengaluru.

I came to software from commerce, with a B.Com and CMA Intermediate. So when I look at a system, I also look at the money moving through it: who pays, what it costs to run, and whether the numbers work. That's useful in blockchain, where a mistake is public and permanent. It's just as useful when a shop owner asks if a website is worth ₹13,000.

The lesson I carry from my own work is to check the economics before the engineering. I once built a flash-loan arbitrage engine that worked very well, then found that the remaining profit per trade was below what it cost to run. I should have checked that first. Now I do, and I'll tell you if the thing you're asking for doesn't make sense for your business.

An opinion most agencies won't share: most small businesses don't need a redesign. They need clear prices, real answers to their customers' questions, and a Google profile that's filled in properly.
