What I'm looking for

I seek backend/platform roles focused on event-driven systems, real-time streaming, and cloud-native engineering with strong emphasis on reliability, automation, mentorship, and measurable performance improvements.

I am a senior backend engineer with over 10 years of experience designing and scaling high-performance, event-driven systems and microservices across cloud environments. I specialize in real-time data streaming, distributed architectures, and API engineering using Kafka, Spring Boot, FastAPI, and Go.

At Confluent I architected and scaled enterprise-grade streaming solutions on Confluent Cloud, delivered sub-second event processing, built AI-integrated data pipelines, and achieved 99.99% uptime SLAs through autoscaling and self-healing clusters. Previously at Zocdoc I re-architected scheduling systems into microservices, built AI recommendation engines, and improved match accuracy by 31% while reducing latency and accelerating CI/CD.

I am committed to building fault-tolerant systems, optimizing streaming performance, and mentoring teams on event-driven architecture, DevOps automation, and best practices to drive measurable business impact.
