India

Message

At Axis Bank, I lead backend engineering for mobile banking services supporting 30M+ registered users under a 99.99% uptime SLA. I optimized Java and Spring Boot microservices, reducing API latency by 35% and database query load by 40%.

I also led a Redis optimization initiative that reduced average memory consumption from 69 GB to 9 GB and infrastructure costs by 50+ lakh per month, with no measurable impact on application performance or availability. Prometheus and Grafana observability improved production visibility and reduced incident response time by 60%.

At Jio Platforms Limited, I developed backend services for Automator.AI and built event-driven workflows using Apache Kafka. I integrated NLP-based task classification, reducing manual automation effort by approximately 80%.

I built and operate Club Sync India, a production SaaS platform used by clubs across India. I work across its backend, cloud infrastructure, deployments, payment integrations, and ESP32/MQTT IoT control platform.
