## Headline

Backend Engineer @ Cars24 \| Java · Spring Boot · Microservices \| Distributed Systems \| Expert @Codeforces \| IIT Roorkee ’25

## About

Backend Engineer \(Java · Spring Boot · Microservices\) at CARS24, building distributed, event\-driven systems handling 60M\+ monthly requests across 3 customer\-facing platforms\. At CARS24, I own contextual recommendation services for PDI, VHR, and Challan — journeys I built drive 41\.4% of PDI orders and 23\.5% of VHR orders\. Led backend platformization post\-acquisition of VehicleInfo and CarInfo, consolidating shared logic into multi\-tenant Spring Boot services across 3 platforms\. Performance work: reduced p95 latency 30–40% and cut production error rate 28% via targeted Redis caching\. Side project — PayFlow: event\-driven payment backend \(Java, Spring Boot, Kafka, PostgreSQL, Redis\) with transactional outbox, idempotency, double\-entry ledger, and row\-level locking\. Stress\-tested to 1,976 req/sec at 35ms p95, 0\.00% errors \(k6 \+ Prometheus \+ Grafana\)\. Stack: Java 17, Spring Boot, Microservices, REST APIs, Kafka, Redis, PostgreSQL, MySQL, MongoDB, Docker, Kubernetes, AWS, JUnit, Mockito, Testcontainers, Prometheus, Grafana\. IIT Roorkee ECE '25 · Codeforces Expert 1701\. Open to backend and platform engineering roles at product\-focused companies\.

## Work experience

SDE 1 at CARS24, Oct 2025 \- Present · 11 mos, Gurugram, Haryana, India, • Designed and shipped fault\-tolerant Java/Spring Boot microservices for contextual recommendation \(PDI, VHR, Challan\) across 3 customer platforms — 60M\+ monthly requests, zero production incidents post\-rollout\. • Architected backend platformization post\-acquisition of VehicleInfo and CarInfo: consolidated shared domain logic into multi\-tenant Spring Boot services, eliminating duplicate implementations across 3 platforms\. • Recommendation services now account for 41\.4% of PDI orders, 23\.5% of VHR orders, and 4\.7% of Challan orders — measured from Feb 2026 onward\. • Improved system reliability: reduced p95 latency 30–40% via targeted Redis read\-through caching; cut production error rate 28% through systematic root\-cause analysis\.

System Research Intern at Indian Institute of Technology, Roorkee, Jun 2025 \- Sep 2025 · 4 mos, Remote, • Applied performance engineering to a high\-throughput real\-time pipeline — reduced critical\-path processing latency 65% \(35\.53μs → 12\.52μs\) through algorithmic profiling, loop unrolling, and data\-flow restructuring across 20\+ modules\. • Demonstrates low\-level performance reasoning transferable to backend throughput optimization and latency\-sensitive system design\.

Undergraduate Teaching Assistant at Indian Institute of Technology, Roorkee, Aug 2024 \- Nov 2024 · 4 mos, Roorkee, Uttarakhand, India

Business Intelligence Intern at Axis Bank, May 2024 \- Jul 2024 · 3 mos, Navi Mumbai, Maharashtra, India, Built centralized data mart consolidating 100M\+ customer records across 3 databases \(SAS, Python, SQL\) for cross\-sell targeting across cards, accounts, and loans\.
