About

I’m a Software Engineer with a focus on backend development and cloud infrastructure. I’ve had the opportunity to work on large-scale monitoring and logging systems, contributing to the redesign of distributed health monitoring services and helping optimize metric ingestion for cost and performance. My experience includes building APIs, serverless solutions, and notification pipelines using tools like Prometheus, Alertmanager, and Grafana. I’m familiar with AWS, Fluentbit, Grafana, Prometheus, and Nagios Core, and I aim to continuously learn and contribute to improving backend systems and cloud operations.
