About Me

Senior Backend Engineer with 5.5+ years of experience building distributed systems, real-time gaming platforms, and cloud-native infrastructure on AWS. I design scalable microservices, fault-tolerant architectures, and high-throughput backend systems leveraging PostgreSQL, caching, and event-driven patterns. I own the full lifecycle, from system design through production operations, reliability, and performance optimization.

I don't just write code. I design systems that survive traffic spikes at 3 AM without waking anyone up. My job is to make sure the infrastructure behind your product is so reliable, you forget it exists.

I think in database schemas, dream in API contracts, and argue with load balancers for a living. If a system can break, I've already thought about it. If it shouldn't break, I've already built it.

Featured Projects

Production systems I've shipped across gaming, fintech, drone airspace, and travel. They range from payment infrastructure handling crores in daily volume to real-time platforms tracking thousands of live events.

Jumbo — India's first gamified shopping app

Jumbo · Jun 2024 — Present

NestJS PostgreSQL Redis AWS

Gamified Commerce & Gaming Platform

India's first gamified shopping app. Built the payments service, multi-currency wallet ledger, and the orders module powering checkout, gift cards, and DigiGold. The platform scaled to ~600K req/min, with ₹5 Cr peak daily payments and 30 Cr+ in-game transactions.

SkyeUTM — drone unmanned traffic management platform

SkyeAir (via CodeChavo) · 2023 — 2024

Node.js AWS Lambda DynamoDB WebSocket

SkyeUTM — Drone Traffic Management

Serverless backend for an unmanned aircraft traffic-management platform regulating shared airspace. Built the deconfliction engine that continuously verifies 3D separation between aircraft and scaled it to 1,000+ drones tracked live, with real-time WebSocket telemetry and APIs for role management, drone registration, and RPTO batch handling.

The Hosteller — backpacker hostel booking website

Quoality · 2021 — 2022

Node.js GraphQL MongoDB Razorpay

The Hosteller — Booking Engine

Owned the backend for one of India's largest backpacker hostel chains, spanning 50+ properties across the country. Engineered a custom booking engine on top of the eZee reservation APIs to lift direct guest bookings, with Razorpay payments and an AWS Lambda / S3 / SES serverless stack.

VHM Infotech · 2022 — 2023

Node.js GraphQL Zoom API React

Skillsture — Learning Platform

A skills-training marketplace connecting learners with instructors across 100+ skills through live, upcoming, and recorded Zoom lectures personalized to the instructors they follow. Built the backend and a GraphQL-powered React admin dashboard, with the Zoom Meeting API driving the live-class scheduling.

eAutoGen — vehicle warranty and insurance platform

VHM Infotech · 2022 — 2023

Node.js GraphQL React REST APIs

eAutoGen — Warranty & Insurance

A vehicle-aftermarket platform where users generate extended warranty and insurance quotes by car brand, model, and year. Built the admin dashboard end to end with GraphQL API integration.

Work Experience

Jun 2024 — Present

Backend Engineer

Jumbo (joinjumbo.com)

Current

Architected the Payment Service and a multi-currency wallet ledger with multi-gateway integration (Razorpay, Cashfree, Paytm), version-aware routing, and payment-capture reconciliation.
Led the Orders module, the largest area of ownership (300+ commits), covering order lifecycle, cash/non-cash deduction waterfall, gift-card redemption, invoicing, plus Product Bundling and DigiGold (Augmont) flows.
Built the Transaction History subsystem and an auto-convert (winnings → game token) engine with risk-gated enablement, syncing state across PostgreSQL, MongoDB, and CleverTap.
Created 17 NestJS modules end to end and integrated server-side analytics & attribution (Singular S2S, CleverTap, PostHog); helped scale the platform to ~600K req/min and 30 Cr+ daily transactions.
Built an async recharge + KYC orchestration layer using a vendor-agnostic Adapter Pattern (~70% lower third-party cost), cut backend load ~50% via CDN caching, and served as primary escalation owner for production incidents.

2023 — 2024

How I Work with AI

AI runs through how I build and debug, from writing code to digging into production issues. Here's the actual stack.

Primary tool

Claude Code

Daily driver for coding, refactoring, debugging and code review, including the architecture discussions that happen before a line of code gets written.

Model Context Protocol

MCP

Wired into the editor to pull real context while debugging: querying data, tracing issues across systems, and operational lookups without switching tools.

Connected to Postgres (read-only) Slack Linear

Ideation

ChatGPT

Brainstorming, exploring approaches, and talking through design trade-offs early on.

AI IDE

Cursor

Fast inline completion for day-to-day editing when momentum matters more than conversation.

06

Writing & Notes

Short write-ups on backend problems I've actually had to solve in production.

PostgreSQL Draft

Fixing PostgreSQL connection exhaustion at 100 RPS

How a gift-card order path hit a ~40% failure rate under load, and the connection-pool fix that brought it back to zero.

7 min read

Payments Draft

Reconciling failed wallet payments without double-charging

Designing a payment-capture reconciliation flow that recovers money stuck between the gateway and the wallet, exactly once.

6 min read

System Design Draft

Designing a multi-currency wallet ledger

Running balances, idempotency, and storing money as integers to kill floating-point drift before it ever reaches a user.
