About

A Ph.D. scientist who became an enterprise AI delivery expert.

I spent eight years at Oracle delivering AI engagements across manufacturing, oil and gas, finance, public sector, real estate, and retail. That work spanned customer discovery, technical design, and Pilot-to-production (P2P) delivery. Before Oracle, four years delivering big-data ML systems on Hadoop for enterprise clients. And before that, two decades of peer-reviewed research in computational physics and planetary dynamics.

That combination is the differentiator: I am a scientist who can sit with the C-suite on Monday and write the production code on Tuesday. I work directly with technical and business stakeholders to turn ambiguous AI ambitions into systems that actually run.

As an independent practice, I work across industries and recommend the architecture that actually fits your problem. Vendor-neutral by design.

  • Ph.D. Physics, University of Notre Dame
  • 30+ peer-reviewed publications
  • 12+ years enterprise AI/ML delivery
  • 10 Oracle Cloud Infrastructure certifications

Services

How I work with clients.

For small firms putting their data to work, and enterprises sharpening their AI delivery. Engagements range from one-week strategy sprints to multi-month production builds, as embedded consultant, part-time AI lead, or in-house advisor.

AI Strategy and Discovery

Identify the highest-value AI and GenAI use cases for your business, scope a defensible POV, and build a roadmap from prototype to production. Executive-fluent technical leadership, no slideware.

Vendor Evaluation

Independent technical review of AI and ML vendor proposals, RFP responses, and platform pitches. Cuts through the marketing to tell you whether the architecture, data assumptions, integration story, and pricing actually hold up. Vendor-neutral by design.

Generative AI Solutions

Retrieval Augmented Generation (RAG), natural-language-to-SQL (NL2SQL), prompt engineering, and GPU deployment. Each built as the right tool for the specific use case.

AI Agents

Production single-agent, multi-tool systems that combine RAG, NL2SQL, web search, to provide access to structured and unstructured data behind one conversational interface. Designed for enterprise data, not toy demos.

Machine Learning Systems

Supervised ML on tabular and time-series data: predictive maintenance, opportunity & risk scoring, forecasting, fraud detection, resource optimization. End-to-end pipelines from data and feature engineering through model deployment & monitoring.

Underlying stack: Python, SQL, pandas, scikit-learn, LLM APIs, vector search, Spark, Hadoop ecosystem, Jupyter, Git, Claude Code, plus a deep Oracle Cloud Infrastructure stack (Oracle Database, Oracle Autonomous AI Database, OCI Data Science, OCI Generative AI service),
as well as conceptual fluency across the major hyperscalers.

Engagements

Three ways to work together.

Hourly project work, or monthly retainers with reserved hours.

Project-Based

$250 / hour

Fixed-bid pricing available for well-scoped projects. Standard response time; for priority access, see the retainer tiers.

Best for: a strategy sprint, vendor review, POV build, custom RAG or Agent integration, or any ML or data analysis task.

  • Direct work: design, code, and documentation
  • Half-day, single-day, or multi-week scopes welcome
  • Progress checkpoints sized to the engagement
  • Final readout and handoff to your team

10-Hour Retainer

$350 / hour

$3,500 / month. Hours do not roll over. Monthly commitment, cancel anytime.

Best for: small teams that want consistent senior AI input on a lighter cadence.

  • Up to 10 hours per month of senior-level AI work, reserved for you
  • Priority response: Slack, Teams, or email within three business hours, not next business day
  • Standing biweekly working session with you and your team
  • Persistent context: I retain working knowledge of your stack, data, and roadmap, so we never restart from zero
  • On-call architecture and code review between sessions
  • Detailed monthly time and progress reporting, so you see exactly where the hours went

20-Hour Retainer

$300 / hour

$6,000 / month. Hours do not roll over. Monthly commitment, cancel anytime.

Best for: teams who want a senior AI advisor continuously engaged with their stack and roadmap.

  • Up to 20 hours per month of senior-level AI work, reserved for you
  • Priority response: Slack, Teams, or email within three business hours, not next business day
  • Standing weekly working session with you and your team
  • Persistent context: I retain working knowledge of your stack, data, and roadmap, so we never restart from zero
  • On-call architecture and code review between sessions
  • Quarterly roadmap review with your leadership
  • Detailed monthly time and progress reporting, so you see exactly where the hours went

Custom engagements welcome. Multi-month projects, advisory boards,
and equity arrangements considered for the right fit.

Selected Work
