Backend engineer building real-time systems at scale — from migrating 30M+ domain records to engineering fraud-detection pipelines that flag threats in under 30 seconds.
Experience
SDE Intern → Senior Associate SDE
Radix, Mumbai- Reduced operational costs 3x across 11 TLDs (.online, .tech, .store, .fun, .host, .space, .press, .pw, .site, .uno, .website) by architecting internal automation in Python and Node.js that replaced 3 external third-party services covering domain governance, abuse-handling, and registrar operations.
- Eliminated the Business Intelligence team's dependency on external SERP tooling by building an in-house analysis platform with multi-step retrieval workflows, automating registrar data extraction across all 11 TLDs.
- Cut manual intervention time 60% by engineering scalable concurrent job-processing pipelines for trust & safety workflows across 11 production TLDs.
- Enhanced monitoring with Prometheus and Grafana across registry platforms serving 11 TLDs, enabling anomaly detection before customer impact.
- Contributed to migrating 30M+ domain records between registry backends — the largest such migration in company history.
Promoted from Intern to Senior Associate SDE in Jul 2026.
Backend Developer Intern
PayRam — Self-Hosted Stablecoin Payments, Remote- Shipped 2 core production features for a multi-chain payment server, owning the full lifecycle from system design through deployment and debugging.
- Cut manual QA effort 90% and improved bug-detection speed 5x by engineering 26 automated end-to-end test cases covering payment workflows and smart contract deployments via GitHub Actions CI/CD.
- Contributed to automated settlement workflows and wallet infrastructure spanning 4 blockchain networks (Ethereum, Base, Bitcoin, Tron) with sub-second settlement targets.
Selected Work
CertWatch
Real-Time Domain Threat Intelligence Platform
A live system that ingests every SSL certificate issued anywhere on the internet in real time via Certificate Transparency logs, flags domains impersonating known brands, and scores each one through an explainable risk engine. A tiered similarity-matching engine replaces naive string comparison, cutting false positives to near-zero across 30+ monitored brands including Indian banks and fintechs. Parallel enrichment workers pull DNS, WHOIS, ASN, and content signals without stalling the pipeline — flagging malicious domains in under 30 seconds, the same threat intel registrar trust & safety teams rely on.
BNBBrawl
Real-Time Esports Wagering on BNB Chain
Built in 16 hours during the BNB Chain Hackathon: a live wagering platform for Valorant Champions Tour matches. Connect a wallet, place on-chain bets against real-time odds, and receive instant payouts through a Solidity escrow contract the moment a match ends. Placed 2nd.
Solana Security Dashboard
On-Chain Exploit & Threat Tracker
A live dashboard tracking Solana exploits and failed transactions in real time, combining Dune Analytics queries with a Puppeteer-scraped historical exploit database. Surfaces fund-loss analytics, exploit timelines, high-frequency-signer detection, and a filterable resource library for security researchers.
Profile
Backend engineer specializing in high-throughput, real-time systems — from migrating 30M+ domain records to building fraud-detection and Web3 settlement pipelines processing tens of thousands of requests a day.
