Build it. Break it. Understand it. Make it better.
Hello
I'm Anmol Kumar (call me Anmol) — a Full Stack Developer focused on precision and performance, known for bridging clean UI with scalable backends and taking ownership from concept to deployment.
I've built and worked on real-world platforms used across multiple cities in India, handling thousands of concurrent users. Most of my work has been around service platforms, booking systems, payments, dashboards, multi-tenant SaaS, and the backend systems that keep these products running.
I enjoy working across the stack, but I'm especially curious about what happens behind the screen — how data should be structured, how APIs behave under load, how background jobs should be handled, how different services communicate, and what happens when the number of users starts growing.
I work mainly with TypeScript, React, Next.js, Node.js, NestJS, PostgreSQL, and MongoDB, along with things like Redis, RabbitMQ, Docker, background workers, payment systems, and cloud infrastructure.
I don't really like thinking of development as just writing code. I like understanding the problem first, building the simplest thing that works, and then questioning it — what happens if this gets bigger? what if this service goes down? can this be faster? is there a better way to design it?
I'm still learning and experimenting with a lot of things. That curiosity is probably what keeps me building. There's still a lot I don't know — and honestly, that's one of the things I like about development. There's always something new to break, understand, rebuild, or make better.

Worked on a production-scale Home Service Management System (HSMS) used by 40+ businesses across 100+ cities in India, including Delhi, Noida, Bengaluru, Kolkata and other major cities. The platform supports operations involving thousands of service providers/vendors every day, covering the complete lifecycle from service discovery and pricing to booking, POS checkout, provider assignment, payments, commissions, taxes, subscriptions, wallets, payouts and settlements.
On the engineering side, I worked across the stack using Next.js, NestJS, PostgreSQL, Redis, BullMQ, Docker and H3 geospatial indexing. I worked on multi-tenant architecture, city and area-based pricing, provider and inventory workflows, background jobs, payment integrations, authentication, dashboards and production APIs. I also worked on query optimization, database indexing, caching and API performance to keep the platform responsive as data and traffic grew.
Alongside HSMS, I also worked on a Quick Commerce platform, building and improving systems around orders, inventory, pricing, delivery workflows and backend APIs. Working on both platforms gave me the opportunity to deal with real production problems.
