Venturi Logic is the consulting practice of Luke Stefurak — an engineer and architect with 10+ years building scalable cloud platforms, developer infrastructure, and data systems across enterprise, healthcare, and defense. I help teams design systems that are reliable, governable, and genuinely operable, then stay hands-on to make sure they actually ship.
Services
Platform foundations
Azure-first and multi-cloud platforms designed around networking, identity, encryption, and governance from day one. Reusable Terraform and Terragrunt modules that turn one-off provisioning into a repeatable standard your team can own after I'm gone.
Pipelines and decision systems
Secure, compliant data architectures — Azure SQL Managed Instance, Synapse Analytics, ADLS Gen2 — with customer-managed encryption and controls that hold up to institutional and regulatory scrutiny. Automated ETL validation and data quality frameworks that catch problems early instead of in production.
Delivery and reliability
CI/CD systems for application, infrastructure, and analytics workloads using GitHub Actions and Azure DevOps. Kubernetes deployment platforms with GitOps (Flux) for secure, auditable, multi-environment promotion. Less manual deployment toil, faster and safer iteration.
Agent-enabled workflows
LLM integration and agentic system architecture done with an engineer's caution: API orchestration, tool sandboxing, workflow automation, and observability baked in rather than bolted on.
How I Work
The right architecture is the one your team can run, debug, and extend — not the one with the most boxes on the diagram. I optimize for what you'll be living with in eighteen months.
Every engagement should move a number you care about: deployment time, iteration speed, infrastructure cost, pipeline reliability, time-to-provision. If a change doesn't show up in something measurable, it's worth questioning.
I move fluidly between strategy and implementation — sitting in the architecture review and the code review in the same afternoon, and translating between engineering, infrastructure, security, and operations teams who too often talk past each other.
I'd rather leave you with reusable modules, documented standards, and a team that understands the system than a dependency on me. Good consulting should make itself unnecessary.
Experience
Architect and technical lead for enterprise Azure data and analytics platforms at one of the world's largest academic clinical research organizations. Designed secure, compliance-aligned data architecture and built the Terraform/Terragrunt standards adopted across multiple environments and engineering teams.
Optimized build and release pipelines for the Windows codebase, meaningfully reducing developer inner-loop iteration time across an org with thousands of contributors. Contributed to large-scale CI infrastructure and applied-ML efforts to improve build reliability.
Software engineering and systems security work across classified programs, including secure networking, encrypted WAN restoration, and real-time data systems for distributed environments.
About
I'm the engineer behind Venturi Logic. I've spent over a decade building the unglamorous infrastructure that lets everything else run — cloud platforms, deployment systems, data pipelines, governance frameworks — at organizations ranging from Microsoft and Lockheed Martin to early-stage teams and my own clients.
What I keep coming back to is this: most teams don't need a bigger architecture. They need a clearer one, with someone who's equally willing to defend a design decision and to go fix the thing that's broken. That's the work I do best.
Venturi Logic is small on purpose. You work directly with me, not a layer of account managers in front of a rotating bench.
Why "Venturi Logic"
A venturi is a deceptively simple piece of engineering: narrow the path, and the flow speeds up. No extra energy added — just a smarter shape. The best results usually come not from adding more, but from designing the constraints well: the right boundaries, the right standards, the right amount of automation. Do that, and throughput takes care of itself.
Contact
I take on a small number of engagements at a time and am happy to start with a no-pressure conversation about the problem before anyone talks scope. A migration you keep postponing, a data system that needs to hold up under audit, infrastructure that needs a real owner — all worth a conversation.
