As Founding Engineer - Backend at Jivi, I architected and scaled key backend systems from scratch, driving performance and reliability across AI-driven products. Key achievements: • Web Crawler: Built a high-performance crawler for medical data, handling 12.5M records and 9M images, with sub-50ms search latency. • Notification Service: Developed a unified system for SMS, Push, Email, and WhatsApp, cutting authentication costs by 50% and ensuring sub-200ms delivery. • IAM System: Engineered a high-performance IAM system handling 40K RPM with <50ms authentication latency using Redis and JWT tokens. • Mobile Backend: Designed a scalable backend for mobile apps, handling 22.3K RPM and maintaining 99.9% uptime with optimised latency under 120ms. • Payment Orchestration: Built a payment system integrating multiple providers, boosting payment success rates to 95% with automated reconciliation.

• Architected a modular, microservices-based Central SMS Service, optimising user messaging operations and achieving 110,000 requests per minute (RPM). Integrated NoSQL databases alongside Kafka streaming for real-time data processing, enabling BharatPe to efficiently store and analyse and perform aggregations on large-scale data. This infrastructure empowered the development of advanced intelligence and analytics on user behaviour, driving improved user engagement and traction. • Led the development of a data-driven sales application for cross-selling, facilitating monetisation and automated payouts for BharatPe’s sales agents. Built a custom rule engine leveraging MySQL, Redis, Kafka, and Spring Boot, enabling seamless handling of complex payout calculations. Implemented multi-threaded processing for asynchronous tasks, ensuring high performance and scalability. The solution improved efficiency in cross-sell activities, driving revenue growth and operational automation.
