Senior Frontend Engineer · Full-Stack JS
Arun Kundu
I'm a software engineer with 6+ years of industry experience — five spent building frontend-heavy products in React, Next.js, and TypeScript, and the rest in backend systems with Node.js, Java, and Spring Boot. I lead teams, ship production systems, and care deeply about architecture.

About
Frontend depth, full-stack ownership, team-first mindset.
I'm Arun Kundu, a senior software engineer based in Dhaka. The last five years of my career have been spent building frontend-heavy products in the React and Next.js ecosystem, working alongside backend teams and shipping at production scale.
Before that, I built backend systems in Java and Spring Boot. Today I'm investing back in that side of the stack — Node/Nest, Postgres, microservices — because I want to keep growing into a full-stack engineer who can own a feature from schema to UI.
Currently at Shikho, I lead a team of two developers and own initiatives like Shikho AI and the Student Portal revamp. Before that, I worked at Monstarlab with borderless teams on international client projects in Saudi Arabia, Japan, and Europe.
