Experience
Lead Developer
Salesforce 2025 - 2026
Designed and built developer-first platform tooling to automate complex backend workflows, focusing on deterministic execution, schema integrity, and safety guarantees. Led development of DataMon, a one-click automation framework that generates backend artifacts from structured inputs, significantly reducing onboarding time and operational errors. Implemented and maintained core platform entities supporting large-scale data ingestion, reporting, and system integrations with strong consistency requirements. Built secure, auditable automation pipelines for database and platform operations, eliminating manual access paths and reducing operational risk. Collaborated closely with platform, infra, and product teams to deliver reliable, scalable backend systems used across multiple internal services. Mentored engineers and enforced high engineering standards around code quality, testing, and long-term maintainability.
SDE II
Snapdeal and Blinkit 2017 - 2021
Built and operated real-time pricing and aggregation systems that processed high-volume events and computed outcomes dynamically based on multiple inputs—conceptually similar to swap routing and price aggregation in DeFi. Designed event-driven backends using streaming architectures to ensure low-latency updates, consistency, and reliability under peak traffic. Implemented rule-based execution engines to apply complex business logic deterministically, mirroring on-chain conditional execution patterns. Optimized data access paths with caching and query tuning to support high-throughput, low-latency APIs. Scaled systems to handle 10× traffic spikes, maintaining correctness and availability during high-load scenarios. Collaborated across services to deliver resilient, production-grade backend systems with strong observability and failure handling.
Lead Developer
Paytm Payments Bank 2015 - 2024
Led design and operation of high-throughput, transaction-critical systems handling large-scale wallet and payment data with strict correctness and availability requirements. Built real-time data synchronization pipelines using event-driven architectures to ensure low-latency propagation and consistency across multiple wallet services. Owned disaster-recovery migrations for critical financial systems, ensuring zero customer impact through careful orchestration, monitoring, and rollback strategies. Drove infrastructure cost optimization and reliability improvements, migrating services and improving operational efficiency while maintaining security guarantees. Strengthened platform security by enhancing authentication flows, patching vulnerabilities, and enforcing operational best practices. Mentored engineers and reduced production incidents by enforcing robust failure handling, observability, and disciplined engineering processes.
Software Developer
Voyzant Inc Canada 2015 - 2017
Built and owned multithreaded backend services for real-time pricing and settlement workflows, ensuring correctness and performance under concurrent load. Integrated with multiple external provider APIs, handling latency, partial failures, retries, and data consistency across systems. Designed backend components with strong emphasis on throughput, fault tolerance, and scalability, optimizing execution paths for peak traffic. Implemented caching and query optimizations to reduce processing latency and improve system responsiveness. Took end-to-end ownership of backend modules, translating business requirements into deterministic and reliable system behavior.
