• Real-time Updates Platform: Led re-architecture, boosting connections/node to 230K (from 25K) with p99 latency ~1.5s (from 5s). Raised throughput to 35K msgs/s at ~20ms p99 (from 5K/200ms). Cut IPL costs from $28K/mo to <$1K/mo, handling 1.5B updates/hr for 10x scale.
• Data Layer Scale-out: Used Vitess for MySQL sharding to manage 400K writes/s, 250K QPS at <15ms p99 with consistency. Enabled horizontal scaling and migrations.
• Real-Time Transaction Reconciliation System: Built system to detect/resolve inconsistencies in distributed stores/streams, improving transactional accuracy.
• ML-based Infrastructure Scaling: Created serverless autoscaler with AWS Lambda, Step Functions, Node.js for ML-driven liquidity prediction. Scaled 50+ ASGs, HPAs, LBs, Elasticaches, EBS for spikes to 18K joins/s, 300K reqs/s. Cut IPL costs, overprovisioning; added monitoring.
• Trust Feature at Scale: Built Spark-on-EMR pipeline for post-match PDF generation, scaling from 1M to 20M+ users/match seamlessly.
• Domain Microservice Split: Led team of 2 to split monolith into 4 microservices for agility. Managed zero-downtime migration with flags, analysis, rollback paths.
• Reactive Migration: Migrated microservice from Spring Boot to WebFlux, fixing CPU issues to cut infra costs 5x under same SLOs.
• Engineering Lead & Product Leadership:: Negotiated requirements, resolved cross-team issues, presented HLDs, coordinated deployments for large projects like social networking , loyalty program for 150M+ Games24x7 users, user profiles/stats, and enhanced contest joins, leaderboards for social networks.
