Infrastructure setup and maintenance

Experience with infrastructure setup and maintenance for a variety of applications and platforms. Operated extreme scale infrastructure at planetary scale.

Cloud & Infrastructure

• AWS: Production cloud infrastructure: IAM, networking, compute, and managed services.
• GCP: Cloud platform delivery: VPCs, workloads, observability, and cost control.
• Terraform: Infrastructure as code: reproducible environments and safe change management.

Orchestration & Fleet

• Kubernetes: Cluster orchestration, deployments, networking, and day‑2 operations.
• Rancher: Kubernetes fleet management: cluster lifecycle, policy, and access control.
• Zededa: Edge fleet orchestration: provisioning, updates, and secure device operations.

Observability

• Grafana: Dashboards, alerting, and operational visibility for teams and stakeholders.
• Cortex: Metrics at scale: ingestion, long-term storage, and multi-tenant query patterns.

Streaming, CDC & Processing

• Apache Kafka: Durable event streaming for high-throughput ingestion and distribution.
• Debezium: Change data capture pipelines from databases into Kafka.
• Confluent Schema Registry: Schema governance and compatibility for event/data contracts.
• Apache Flink: Stateful stream processing and low-latency transformation workloads.
• Apache Calcite: SQL parsing/optimization and query federation across diverse sources.

Databases, Warehousing & BI

• PostgreSQL: Reliable relational database operations, performance tuning, and migrations.
• CockroachDB: Distributed SQL with resilience, geo-replication, and strong consistency.
• YugabyteDB: Distributed SQL for globally scalable transactional workloads.
• InfluxDB: Time-series data storage for metrics and telemetry use cases.
• Apache Superset: Self-service BI dashboards and exploration over operational/analytical data.
