I’m John Larson and this is LuminalData.

I help manage and analyze data. Since 2000 I have grown from a developer, to a DBA, and then to a leader in IT. Specializing in databases, queries, reporting, and infrastructure I can help you develop a plan and execute that plan in your data strategy.

I help organizations turn complex data and infrastructure into dependable, scalable platforms that move the business. Over the last decade-plus, I’ve led database, data engineering, and delivery teams through high-stakes transformations—modernizing data centers, hardening platforms for compliance, integrating AI with existing data stacks, and building the operational muscle that keeps critical services running.

​

What I do best

  • Lead high-impact programs that modernize data platforms, reduce risk, and cut cost—without slowing the business.

  • Architect and tune databases at scale, improving performance, reliability, and observability across MSSQL, DB2, and PostgreSQL.

  • Operationalize data & AI, integrating LLMs and automation (Ollama, n8n, ChatGPT) with existing pipelines and governance.

  • Build accountable teams and delivery frameworks (Agile/iterative) with clear KPIs, clean runbooks, and transparent reporting to execs.

  • Navigate audits & compliance (HIPAA, HITRUST, CMS) and vendor negotiations to protect uptime and budgets.

​

Highlights & wins

  • Modernized a large healthcare data estate—directed two squads of 12 data engineers to migrate 600+ TB during a data-center move; drove $5M+ annual cost reductions and improved reliability (incident rate down 21%, outages down 10%).

  • Optimized vendor spend—secured $600K in recurring savings by renegotiating maintenance contracts.

  • Accelerated delivery—stood up a new services/delivery function that cut application/server time-to-market by 15%, and improved data service request throughput by 14%.

  • Lifted revenue and reduced risk—led a merger-driven database migration that added $50M in revenue; implemented SQL Server monitoring that cut operational impact 61% and revenue loss 30%.

  • 4× faster client data loads—rebuilt ingestion and validation flows to deliver data to end users dramatically faster (and with better visibility for Finance and Claims).

    ​

How I lead

I’m a hands-on, metrics-driven leader who hires for curiosity and accountability. I put structure around complex work (roadmaps, charters, service catalogs), make health visible (dashboards, scorecards, SLOs), and give teams the autonomy and context to deliver. I collaborate closely with security, compliance, and product to ensure platforms meet real-world needs—not just theoretical SLAs. And I mentor relentlessly: strong teams outlast strong projects.

​

Selected initiatives I can replicate for you

  • Data center or cloud migrations with zero-drama cutovers, rollback plans, and capacity planning baked in.

  • Observability & SRE for data—from custom SQL Server monitoring (PowerShell/SSRS) to platform-wide health dashboards, capacity models, and incident playbooks.

  • Compliance-first hardening—audit-ready processes for HIPAA/HITRUST/CMS with traceable evidence and repeatable controls.

  • M&A data integration—due diligence on schemas and workloads, migration runbooks, and post-merge performance stabilization tied to revenue milestones.

  • Delivery transformation—service catalogs, ServiceNow KPIs, intake → prioritization → delivery workflows, and executive reporting that actually informs decisions.

    ​

Tooling & platforms

  • Databases: MSSQL, IBM DB2, PostgreSQL

  • Pipelines/Integration: SSIS, Informatica (incl. B2B), n8n

  • Warehousing/Big Data: Hadoop, Snowflake (SnowPro Core certified)

  • BI/Reporting: SSRS, Power BI, Tableau

  • AI & Automation: Ollama, ChatGPT, Claude

  • Cloud: AWS, Azure

    ​

Recognition

  • Galen D. Powers Award (HMS) — company’s highest honor recognizing customer focus, integrity, collaboration, accountability, and innovation.

The bottom line

If you need an IT leader or data architect who can stabilize today’s platform while building tomorrow’s—someone who speaks exec, engineering, and operations—I’m your person. I’ll bring a pragmatic roadmap, measurable outcomes, and a calm, delivery-first approach to your most complex data challenges.
