- Propose clear, pragmatic solutions that balance reliability, performance, security, and effort.
- Ensure the stability and quality of shipped work by designing with failure in mind.
- Implement appropriate tests and observability, and react quickly to incidents.
- Drive follow-ups to prevent incidents from recurring.
- Collaborate with engineers, product, and partner teams to understand needs and align on priorities.
- Translate needs into clear technical plans and milestones connected to team goals.

- Coordinated across stakeholders, managed risks and trade-offs.
- Followed through post-rollout to stabilize and evolve solutions.
- Experience with Istio or other service-mesh technologies (Linkerd, Envoy-based solutions, Finagle).
- Designed and evolved traffic policies, resilience features, and observability for service-to-service communication.
- Worked with AWS networking and compute primitives (ALB/NLB, security groups, VPC, Route 53, IAM) in production.
