Team Lead & Senior Software Engineer · based in Noida, India
Kolkata is also written Calcutta.
I am Aman Kumar Singh — also written Aman Singh, Aman K Singh, or simply Aman — a Team Lead and Senior Full Stack Engineer. To be direct about it: I am based in Noida, not Kolkata. What brings me to this page is the work I do with clients and engineering teams in Kolkata.
East India’s technology centre. Across 6+ years I have shipped 15+ production applications and led teams of 5–10 engineers, working end to end: React and Next.js on the front, Node.js and NestJS services behind it, PostgreSQL and Redis for data, AWS for deployment.
Kolkata’s Sector V and New Town hold a large IT-services base, with fintech, education, and media businesses driving most of the product work. Kolkata engagements often involve modernising a working-but-aging system, which is migration planning as much as coding — and the planning is the risky part.
Aman Singh is a common name, so here are the accounts that are actually mine. If a profile is not linked from this page or from amanksingh.com, it is not me.

Aman Singh is a very common name in India, so to be specific: this is Aman Kumar Singh, a Team Lead and Senior Full Stack Engineer in Noida, a 2015–19 Computer Science graduate of JUET, currently at JellyFish Technologies.

Full-stack engineering: React and Next.js interfaces, Node.js and NestJS microservices, PostgreSQL, MySQL, MongoDB and Redis for data, and AWS with Docker and Kubernetes for deployment. Over 6+ years he has shipped 15+ production applications, including a financial platform serving 50,000+ users and an insurance platform handling ₹10Cr+ in annual transactions. For Kolkata specifically, that most often means content platforms and publishing workflows that survive a traffic spike.
