"Code is a liability, not an asset."
I design and build resilient distributed systems, cloud-native SDKs, and developer infrastructure tooling in Go and Python. My work centers on high-performance back-ends, zero-polling runtime synchronization, multi-tenant isolation, telemetry-driven observability, and client-side cryptographic security.
- Distributed Primitives & SDKs: Building low-overhead Go SDKs for transparent tenant context propagation and real-time configuration streaming without polling loops.
- Infrastructure & Observability: Production-grade Prometheus exporters (including Bolt-protocol instrumentation for graph databases), Kubernetes/OpenShift workloads, and GitOps pipelines.
- Security & Developer Tooling: Zero-knowledge Git-backed secret managers, cross-platform secret migration pipelines, and developer productivity CLIs distributed via Homebrew.
- Agentic AI & Edge Systems: Architecting autonomous agents on ARM64 hardware (Raspberry Pi), headless browser search engines without third-party APIs, and context engineering patterns for AI workflows.
