Scott Severance

Principal AI Engineer
Applied AI and Agentic Systems

I build the production ML and agentic AI systems a Fortune 15 People Analytics organization runs on, then prove what they were worth with real causal inference: a 47-function ML engine inside the Qlik query layer, three Model Context Protocol servers wiring LLMs into live enterprise data, and a Brandon Hall Gold Award for compliance analytics. Nine years of production ML on two decades of enterprise analytics.

About

From First Model
to GenAI Platform at Scale

I built Verizon HR L&D's first production machine learning model in 2017. Today I build the infrastructure underneath enterprise AI (gRPC services, MCP servers, agent pipelines) and own the outcome metric from prototype to production.

As Principal AI Engineer at Verizon, I am a technical lead in Verizon's AI transformation, and I am the sole technical owner on most of what I ship. That means I write the production code as well as the architecture: a patent-pending multimodal data fusion engine that guides Verizon's AI adoption; a Python/gRPC engine exposing 47 machine learning functions as first-class Qlik expressions, deployed as a production service; three Model Context Protocol servers, the largest exposing 111 tools across a Claude/OpenAI/Azure abstraction with OAuth 2.1; and the association rule learning engine that won a Brandon Hall Gold Award for compliance analytics.

The other half is measurement. I hold graduate-level applied statistics and use it for real causal inference (synthetic control, difference-in-differences, ANOVA with post-hoc correction, every sample Cochran-sized), which is how program impact across 77 initiatives gets validated rather than asserted. I also fine-tune models myself, LoRA and full-parameter, on an 8×A100 DeepSpeed cluster.

Top Performance rating three consecutive years, with a Brandon Hall Gold Award for compliance analytics and six open-source AI frameworks on GitHub.

Native ML and NLP Functions Inside the Qlik Engine

A Python/gRPC Server-Side Extension that turns HDBSCAN clustering, Prophet forecasting, spaCy NER, market-basket analysis, Keras inference, and the full scikit-learn train/predict/score lifecycle into first-class Qlik expressions, evaluated live against the user's current selection. Deployed as a production Windows service on an on-prem cluster.

Signature Systems

Four Things I Built
End to End

Architected, coded, deployed, and operated, with the problem each one solved and the result it produced. These are the systems I would walk you through in a technical interview.

01

ML Inference Inside the Query Layer

Qlik's expression language has no machine learning surface. Every model-backed metric had to be precomputed outside the tool and re-imported, which was slow and cut off from the user's live filter context.

I built a Python/gRPC Server-Side Extension exposing 47 native functions (HDBSCAN clustering, Prophet forecasting, the full scikit-learn train/predict/score lifecycle, spaCy NER, market-basket analysis, Keras inference), callable as ordinary chart expressions and evaluated against the current selection. Deployed as a production Windows service on an on-prem cluster.

Result: Qlik went from a static BI layer to a live ML inference surface for the whole People Analytics organization; any app can call a trained model against the user's live selection.

02

Governed LLM Access to Live Enterprise Data

Claude and Gemini Enterprise both needed a safe, auditable path to read and act on live Qlik data, cloud and on-prem, without hand-rolling a fresh integration per provider.

Three independent Model Context Protocol servers. The largest exposes 111 tools behind a Claude/OpenAI/Azure provider abstraction with OAuth 2.1: app discovery, field inspection, hypercube queries, master-item CRUD, sheet and visualization creation, selection-state management. A second ships to the team with bundled certs and SSO/EID auth against on-prem Qlik Sense.

Result: any MCP-compatible client gets governed, tool-level access to both Qlik estates, the connective layer under most of the 2024-2026 AI work.

03

Measuring Risk: Compliance Analytics

Code of Conduct training produced scores across the workforce but no view of where compliance risk concentrated or which employees needed remedial learning.

For Verizon Legal, I built an association rule learning and data mining engine over Code of Conduct training scores, with XGBoost + SHAP risk clustering, and fed it into a heatmap that surfaces hotspots, flags potential violations, and identifies the employees to target with early intervention and remedial learning.

Result: Brandon Hall Group Gold Award, Best Advance in Learning Management Measurement/Business Impact Tools, Excellence in Technology Awards, December 2020, for "Measuring Risk: Verizon's Innovative Approach to Compliance Analytics."

Getting 20 Analysts Into a Real Git Workflow

An org-wide agentic-AI push meant handing modern tooling to people whose job title is not engineer; most had never opened a merge request.

As one of two Maintainers on a 21-contributor, 120-commit repo, I authored the governance framework the whole team worked inside: a root CLAUDE.md, path-scoped rule files for data quality, HR privacy, and Qlik standards, plus an on-demand skills library. Then I personally onboarded ~20 non-technical analysts onto branch, merge-request, and review.

Result: they shipped working artifacts through real code review inside two weeks.
