@rheniusvinoraj
Senior engineering manager specializing in architecture, performance, and scalable systems.
What I'm looking for
I am a Senior Engineering Manager with 13+ years of experience designing architectures, optimizing performance, and leading high-impact engineering teams. I have deep hands-on expertise in Java, Spring Boot, Node.js, cloud deployments, caching strategies (Redis, Hazelcast, Memcached), and event-driven systems using Kafka.
Throughout my career I have led large teams (40+ engineers), executed migrations to modern runtimes (Java 17), implemented caching and API performance improvements that reduced latencies, and strengthened CI/CD, testing, and observability practices such as PostHog for diagnostics.
I am focused on building scalable SaaS architectures, driving measurable performance gains, and fostering engineering excellence through code reviews, automation, and SRE practices to deliver reliable, high-throughput backend platforms.
