Developer · Integrations & Automation
REST & GraphQL integrations, automation with Python and Node.js, and root-cause investigation with Datadog across AWS/Azure, Docker, and Kubernetes environments.

Professional Summary

Developer experienced in integrations and automation, working with Python, JavaScript/TypeScript, and Node.js. Strong background in REST and GraphQL APIs, SQL Server, observability with Datadog, and cloud environments (AWS/Azure) using Docker and Kubernetes.
