Senior Full-Stack Engineer & Tech Lead
I build systems people depend on daily — from the Spring Boot record that gets NYC students to school to a securitization engine that chews through 100,000+ loan accounts.
About
I'm a Senior Full-Stack Engineer and Tech Lead based in New Delhi with 6+ years shipping systems people actually depend on daily. I currently lead SentryRide — the platform the NYC Department of Education uses to get students to school — owning the Spring Boot system of record and the Express service that assigns drivers against Google Route Optimization. Java and Spring Boot on one side, Node, NestJS and Next.js on the other, Postgres and Mongo underneath, all of it on AWS.

Full-Stack Web Apps
Production web apps end to end with React, Next.js and Node.js — SSR and ISR where it counts, tuned for fast first paint and real scale.
Backend & Microservices
Transactional cores in Java and Spring Boot, optimization and passenger services in Express and NestJS — clean service boundaries over one bloated runtime.
Cloud & DevOps
Shipping on AWS with Docker and GitHub Actions — blue-green rollouts into ECS that turn an evening of babysitting into a 12-minute pipeline.
Work
SentryRide
The platform NYC's Department of Education uses to get tens of thousands of students to school — four services spanning a Spring Boot system of record, a routing engine and a DOE dispatch console.
Securitization Platform
Ingests loan pools of 100,000+ accounts, models cashflow waterfalls and generates investor-ready Excel reports — every artefact backed by an audit trail.
NuralSales
React and Next.js frontends on Node.js services for a suite of enterprise sales products, built on a shared component library four teams adopted.
JK Connect
Field-sales platform with Redis-cached feeds in front of MongoDB, containerised with Docker and shipped to AWS.
