my work 🛠️

Summary

The majority of my experience involves building integrations and tools in the Observability space. When it comes to building new apps or features, I am always looking for areas to improve productivity, eliminate operational overhead and costs. Today, I am actively seeking new opportunities to apply this expertise in both full-stack and backend engineering.
