At PostHog, I build AI-driven analytics features that improve real-time data processing and user analytics accuracy using Python and Kafka.

I architect RESTful services with Spring Boot and AWS Lambda, optimize Elasticsearch search, and strengthen CI/CD workflows through Jenkins-based automated testing and deployments.

Previously at Endava, I led developers delivering cloud applications with AWS and React, while scaling Node.js and Express backend services for high-traffic applications.

I also build responsive Angular and React interfaces, manage PostgreSQL and Redis data solutions, and mentor developers on Docker, Kubernetes, and coding standards.
