About

Senior Software Engineer at Real, building scalable backend platforms and distributed systems. Over the last 6+ years, I have designed and scaled revenue-critical platforms across real estate, hospitality, finance, and IoT domains. My experience spans multi-tenant SaaS architecture, event-driven systems, real-time data processing, platform modernization, and performance optimization. Prior to Real, I led backend initiatives at Treebo Hospitality Ventures, where I transformed a legacy Property Management System into a multi-tenant SaaS platform and improved pricing service latency by 68%. Earlier, at Exalens, I architected real-time streaming systems processing thousands of concurrent device events, and at D. E. Shaw, I contributed to production-grade backend and observability platforms in a high-reliability engineering environment. My core expertise includes Distributed Systems, Backend Architecture, FastAPI, Python, PostgreSQL, Kafka, RabbitMQ, Redis, Docker, Kubernetes, and Cloud-Native Engineering. Passionate about solving complex scalability challenges, building resilient systems, and turning ambitious product ideas into reliable platforms used at scale.
