Summary

Field Deployed Engineer with 15+ years walking into ambiguous enterprise environments, shaping the AI solution, prototyping working systems, and owning delivery cradle-to-grave. Hybrid presales-architect-builder across financial services, healthcare, federal/DoD, and utilities. Influenced $50M+ in enterprise AI outcomes, led 100+ production deployments across regulated industries, and built and scaled a global solution architecture practice from 3 to ~50 across four regions. Current technical focus: accountability infrastructure for agentic AI - permissioned ledger and Merkle-proof audit chains that let AI agents operate in liability-sensitive environments where regulators, auditors, and counsel need cryptographic proof of agent authority, scope, and execution.

Quant

Vice President, Business Solutions - GTM, Customer Strategy & Agentic Business Lifecycle

Frameworks, Operating Models & Value Engineering

  • Designed VEQTOR, the Quant Vision Engine for Knowledge, Transformation, Operations, and Revenue: a six-axis GTM blueprint aligning presales, demo engineering, skunkworks, and sales operations into one governed customer lifecycle system.
  • Authored Quant's Enterprise Operating Blueprint, mapping a nine-phase customer journey across business-unit quadrants so Sales, Product, Delivery, and Customer Success could qualify, demo, scope, implement, and expand enterprise AI opportunities with a common operating language.
  • Authored Quant's Value Engineering Framework with CFO-ready ROI formulas tying agentic workflow modernization to measurable outcomes including containment, FCR, labor capacity, cycle-time reduction, and cost-to-serve.
  • Built the AI Discovery and Qualification toolkit: opportunity qualification framework, use-case discovery guide, solution discovery workbook, BRD templates, and strategic demo playbook for consistent early customer conversations and technical win planning.

Enterprise Engagements & Technical Architecture

  • Led meter-to-cash end-to-end business orchestration engagement for utility client PPL, spanning field technicians, billing, and regulatory compliance workflows - not a contact center play, but a cross-functional agentic workflow design across a regulated utility operating environment.
  • Designed the Agentic Business Lifecycle to extend beyond chatbot demos into orchestrated workflow automation with human-in-the-loop approvals, evidence capture, and closed-loop KPI feedback.
  • Developed an Enterprise Work Graph model normalizing ServiceNow, Jira, Salesforce, ITIL, Agile, and automation work into a canonical flow: signal to work item to decision to action to evidence to outcome.
  • Authored a voice-streaming connector strategy across major CCaaS platforms, reducing multi-platform integration effort and giving Sales and Engineering a reusable architecture for technical customer questions.

SoundHound AI / Amelia (formerly IPsoft Amelia)

Senior Director, AI for Enterprise & Global Solution Architecture

Regulated Enterprise Engagements & Practice Build

  • Led enterprise solution architecture across regulated industries: financial services (BlackRock, Mastercard, Bank of America, Wells Fargo), healthcare (University of Miami, Wellstar, HCA RFP), federal/DoD (US Army via GDIT under FedRAMP, USMC via Deloitte under DoD clearance), and retail/services.
  • Co-built Amelia's healthcare practice from zero, partnering directly with CMIO, CXO, and contact-center stakeholders to redesign patient access, intake, scheduling, waitlist recovery, no-show recapture, post-visit collections, and service operations through conversational AI and workflow modernization.
  • Founded NASA (Network of Amelia Solution Architects) and scaled the global SA/SE practice from 3 to ~50 across four business units and four regions (NA, EMEA, APAC, LATAM).
  • Designed the global SA/SE operating model: hiring profiles, onboarding, enablement curricula, certification paths, demo standards, Communities of Practice, utilization standards, and regional delivery cadence for consistent technical partnership across regulated buyers.

Revenue Influence, Demos & Technical Execution at Scale
