About

Keeping software and systems running reliably in production is at the center of my work. I have worked on incident management, troubleshooting and monitoring with Kibana, Grafana, AppDynamics, MSSQL and MongoDB.

I translate business needs into technical requirements and deliver sustainable solutions through API and RESTful service integrations. Alongside that, I build my own apps and websites.
