I'm offering
A senior engineer & technical leader with 20 years of experience building and operating online services, including at Facebook, major ISPs and many startup companies.
My core technical background is in DevOps, Site Reliability Engineering, Linux, AWS, GCP and Kubernetes. Some of the tools / methodologies I've recently used or am interested in include: GitOps (Kustomize, Flux, Kapitan, Helm), service meshes / API gateways (Istio, Linkerd, Kong, Envoy), immutable infrastructure (Ansible, Packer), serverless computing (Lambda, Cloud Run)
Beyond hands-on engineering, I am also a technical leader with keen awareness of product & business matters, who can be relied on for technology vision, systems design, technical operations, mentoring and general engineering wisdom.
I excel at understanding short vs long-term trade-offs, identifying performance bottlenecks & future technical debt, quickly learning and assessing new pieces of technology.
