Technical Architect at Paytm Payments Bank, Mar 2022 - Present · 4 yrs 6 mos, Led CQRS re-architecture of the PPI wallet platform, scaling transaction processing to 20,000 TPS at 30ms P95 latency with zero accounting inaccuracies across millions of daily transactions. Championed Debezium CDC adoption, reducing RBI-mandated EOD regulatory reporting from 20 hours to 6 hours while maintaining 100% platform availability during the transition. Drove contract-first API design and idempotency standards across the payments stack, cutting the add-money failure rate from 3% to 1%. Implemented state machine-based transaction lifecycle management, achieving 0% data discrepancy in reconciliation across all wallet operations. Migrated AWS operations to a Mumbai data center with 99.9% uptime and zero data or fund loss on a regulated payments platform. Optimised the payments data warehouse using Parquet-based streaming design, reducing warehouse size by 80% and improving Spark ingestion time by 40%. Built, scaled, and mentored a 30-engineer cross-functional team (backend, SRE, QA) across multiple platform re-architectures, sustaining high-performance delivery through continuous structural change. Built a production-grade NL-to-SQL engine over a Hadoop/Hive payments DWH (5 schemas, 1,000+ tables, ~3M daily rows) using hybrid retrieval — Elasticsearch BM25 + Qdrant vector search + RRF fusion — reducing ad-hoc analytics turnaround from hours to under 200ms. Designed a three-layer schema retrieval pipeline with BGE-M3 embeddings and cross-encoder re-ranking, achieving >90% top-3 retrieval accuracy across transaction, merchant, compliance, and aggregate domains. Implemented self-healing SQL generation with one-shot error correction, reducing SQL execution failures from ~15% to ~3% by feeding Trino error context back to the LLM; system now handles 500+ analyst queries/month.
