What I'm looking for

I seek a leadership role where I can drive architecture and performance improvements, mentor engineers, and deliver scalable, reliable SaaS platforms with strong observability and automation.

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.
