Systems Architecture

Architecture Patterns

PatternApplied In
Event-Driven PipelinesSIEM Platform — decoupled log ingestion across agents, managers, Logstash, OpenSearch
Shared-But-Isolated Multi-TenancySIEM Platform — Document-Level Security (DLS) for tenant isolation in shared datastreams
Hot/Warm Storage TiersSIEM Platform (ISM), K8s Platform (tiered Ceph pools)
Immutable InfrastructureK8s Platform — Talos Linux, no SSH, no drift
Local-First SyncStateless PWA — offline-capable, sync-on-reconnect

Cloud Experience

Hands-on experience with AWS, Azure, and Google Cloud. Recent work has been on-prem because the economics favored it for always-on, storage-heavy workloads. The skills transfer directly: EC2 sizing informs bare-metal sizing, S3 informs Ceph design, VPC networking informs on-prem segmentation.
