About Me
I'm a software engineer with a deep focus on building resilient, observable backend systems. With hands-on experience across payment platforms, EdTech systems, and e-commerce infrastructure, I specialize in designing microservice architectures that scale.
My expertise spans from building event-driven pipelines with Kafka and NATS, to implementing comprehensive observability stacks with Grafana, Prometheus, and OpenTelemetry. I'm passionate about DevSecOps practices and cloud-native development on AWS.
