Implemented Kafka event-driven pipelines and Bull/Redis task queues for background processing and cache invalidation across distributed
services.
Optimised PostgreSQL and MongoDB query performance through indexing, partitioning, and connection pooling — sustaining throughput under
peak load.
Containerised services with Docker; deployed to AWS ECS/EKS via Kubernetes with Terraform-provisioned infrastructure.
Set up GitHub Actions CI/CD pipelines with automated testing, linting, and blue-green deployments.
Mentored junior engineers on Node.js async patterns, React component architecture, and API design best practices.
