System Architecture & Cost Optimization: Designed and implemented highly concurrent, distributed caching systems for third-party identity vendors (Experian, Tartan), reducing redundant API calls by up to 63% and saving the company over ₹3.76 Cr annually. Infrastructure Migration: Executed a zero-downtime migration of a highly critical Temporal cluster from Astra DB to MySQL across multiple environments; decoupled default and visibility stores, reducing required pods and resulting in ₹2.4 Cr in annual infrastructure savings. Design Patterns & Vendor Integration: Re-architected the bank verification flow utilizing the Strategy pattern to integrate multiple vendors (Decentro, HDFC), reducing per-fetch costs by 32% while increasing overall success rates by 8% through custom fallback pipelines (Penny Drop validations). Service Consolidation: Streamlined the internal architecture by consolidating and deprecating legacy microservices, reducing resource overhead across 17 onboarding services, and optimizing CPU/memory allocations. Resiliency & Security: Implemented comprehensive circuit breakers across high-throughput endpoints (Auto Fetch PAN/Name/Bank) to gracefully handle third-party vendor downtimes and prevent cascading failures (BulkheadFullException). Data Privacy & Compliance: Spearheaded a cross-service PII log-masking initiative, building custom logging agents with optimized Regex to sanitize sensitive user data (Aadhaar, PAN) at runtime without degrading production CPU performance. Mentorship & Code Quality: Enforced SOLID principles and reviewed over 600 PRs in a single year to prevent architectural regressions; acted as the primary technical point of contact for complex debugging (heap/thread dumps), actively mentoring SDE-1s, interns, and unblocking senior peers on Kafka and Temporal implementations.

Exchange Integration: Integrated the Kucoin exchange to serve as a resilient backup during Binance market fluctuations, successfully exposing a wider array of Asian market tokens to the Indian user base. Order Workflows: Implemented notification flows for Spot and Margin orders, and developed balance locking and reconciliation systems for Spot orders. System Design: Created an OTC three-way system for settling off-exchange transactions; designed and implemented dynamic delisting, scheduling maintenance time, and safety percentage buffers for Margin markets. API & Middleware: Developed a middleware layer for strict request validation and enabled automatic Spec and Swagger generation for the main codebase. Performance Optimization: Improved price alerts, order flows, system health checks, and Coinfirm report generation, while creating Insights for Orders providing periodic snapshots for company funding wallets. Recognition: Awarded "Performer of the Month" in March and September 2021.
