Software Development Engineer 2 at Flipkart, Sep 2026 - Present · 1 mo, Bengaluru, Karnataka, India

Software Development Engineer 1 at Flipkart, Jul 2024 - Sep 2026 · 2 yrs 3 mos, On-site, • Engineered authorization middleware plugins utilizing Redis- based token caching to securely expose Ads APIs to external agencies. Sustained 2,000 QPS, enabling 10+ active agencies to launch 2,100+ campaigns generating Rs 20+ Cr in revenue • Architected a client-route distributed rate limiter for the ex- ternal API Gateway using Redis ZSETs and Lua scripts. Imple- mented randomized epoch IDs for sub-millisecond collision resolution, enforcing a strict 400 QPS guardrail to prevent cascading downstream failures • Spearheaded a zero-downtime migration to a Centralized Au- thZ platform for external and internal advertisers via dynamic feature flags, orchestrating dual-writes across distributed systems using the Strategy pattern and asynchronous non- blocking I/O to prevent cross-service RPC bottlenecks • Scaled Campaign Manager Service throughput from 1.5k → 5k QPS via query optimization, caching, and payload slimming, personally owning 30–40% of the performance gains • Architected a Java-based PII tokenization SDK to enforce data compliance across 10+ core SQL tables, abstracting emails into centralized AccountIDs. Engineered backward- compatible APIs with opt-in latency bypass flags to minimize cross-service network overhead • Developed high-volume Spark jobs on the Cloak framework to process∼1 TB of daily data, computing L2 scores for recom- mendation ad pipelines • Launched Product Contextual Ads (PCA) backend on Flipkart Minutes, enabling 550+ campaigns worth Rs 1+ Cr
