From physics to AI agents
Sakthi Vignesh is a freelance AI agent developer and full-stack engineer in Coimbatore, India. He builds AI agents, MCP servers and automation for businesses, and takes on projects through his own freelance brand, Vantaverse.
The short version
I studied physics because I liked how things work. At Karpagam Academy I taught myself C in Atom and PowerShell, just to see what I could make. Then life said “get a job”, and I spent four years at TNQ Technologies, first in quality checks, then as a production editor running research publishing for international clients.
Good job, good people, but the real buzz came from code. In 2023 I left, trained full-stack at NSchool Academy, and joined KPR Technology, where a React hire got handed a React Native app and learned it anyway. At Hyperready Technology I built the whole BookWedGo ecosystem, a Kalyan Jewellers campaign with a 100,000-URL sitemap, and now DeepSpot, an AI text-to-SQL product.
Today my focus is AI agents that do real work: MCP servers, browser automation, AI testing, and the prompts that hold them together. Through my freelance brand, Vantaverse, I help businesses in Tamil Nadu and beyond put them to work. The ops years turned out to be the secret weapon: I’m most useful on the client call.
