I'm a systems and software engineer and solutions architect with 15+ years of professional experience spanning software development, infrastructure, observability, data platforms, compliance, and large-scale technical operations.
I spent seven years at Virtustream / Dell Technologies, ultimately serving as the technical product owner and principal architect for global monitoring and compliance. Today I'm applying that systems background to local AI inference, automatic speech recognition, Rust, hardware-aware optimization, observability, reproducible evaluation, and local-first software.
I've worked with Linux and open-source systems since 2004 and tend to build at the boundaries between software, operating systems, infrastructure, hardware, and measurement.

I like engineering problems where correctness and evidence matter as much as getting something to run.
That usually means:
- Rust, Python, Bash, Linux, containers, and systems integration
- LLM and ASR inference, quantization, benchmarking, and model evaluation
- latency, throughput, accuracy, memory, and resource measurement
- explicit architectural boundaries and reproducible test harnesses
- observability, infrastructure automation, and performance analysis
- privacy-preserving local and offline systems
- local-first browser applications using Rust, Leptos, WASM, and IndexedDB
At Virtustream, I owned architecture, technical priorities, operational standards, and cross-functional requirements for global monitoring and compliance across enterprise, federal, and Epic healthcare environments.
My work included architecture across 15 multi-tenant colocation sites and more than 7,500 VMs, leadership of a roughly 1 PB HBase/Hadoop-to-BigQuery migration, delivery of a FedRAMP High GCP extension through JAB authorization, observability modernization across VMware and infrastructure platforms, and vulnerability-remediation leadership across more than 2,500 assets.
I also built and scaled automation and operational practices with Ansible/AWX, Python, Bash, Prometheus, Grafana, Zabbix, Kubernetes/K3s, ServiceNow, and related infrastructure, while helping grow the global monitoring support organization from 5 to 25 engineers.
Earlier in my career I worked in enterprise mobile/software engineering, e-commerce production systems, Java, data integration, technical support, and systems engineering.
Across projects, I try to make the evidence boundary explicit:
define the contract → implement the system → measure it → preserve the evidence → state only what the evidence supports.
That includes publishing negative results and failed gates when they are useful, pinning important dependencies and datasets, distinguishing measured results from planned work, and keeping private data local whenever practical.
For detailed architecture, methodology, and measured results, see the technical portfolio.
