Senior🎓
Top SchoolWilliam L is a pragmatic software engineer with 13 years of experience specializing in the ops side of DevOps, currently building platform reliability and back-end systems at bol.com. He excels at automation and “gluing” disparate systems together, with a strong track record across monitoring, logging, service discovery and Kubernetes-era tooling. An active open-source contributor, he’s enhanced projects like Prometheus Operator, ContainerPilot and LinkedIn’s Iris and Oncall—work that spans Thanos/GCS integrations, Consul-enabled container discovery, and LDAP-aware on-call APIs. Comfortable in Go and familiar with Puppet, Terraform, Prometheus, Grafana and Google Cloud, he pairs coding skills with hands-on operational experience to keep services running reliably. Outside work he channels his technical eye into photography and video editing, while also learning Japanese and caring for rabbits—an attention to detail that surfaces in both code and craft.
