## About

```text
At Cisco Systems - Network Assurance Data Platforms, I own production reliability for distributed systems including Spark, Kafka, Airflow, and RDS in AWS. I designed and operated Kafka and Hudi streaming systems for near real-time data processing.

I’ve led incident response, root cause analysis, and recovery for critical outages, and debugged issues such as JVM memory leaks and heap OOMs. I also improved performance through resource tuning and workload optimization.

At Cisco Systems, I built Python automation for operational workflows and designed containerized environments with Docker images that started 40% faster. I implemented monitoring pipelines with Prometheus, Grafana, and Datadog, and led zero-downtime TLS CA rotation across 90+ RDS instances.

At Accenture, I led a team managing production infrastructure and deployments for cloud-native applications. I built CI/CD pipelines, automated infrastructure provisioning with Terraform and Ansible, and worked on disaster recovery testing and PostgreSQL performance and cost optimization.
