Quant

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

SE Operating Model & Methodology

  • Designed VEQTOR — the Quant Vision Engine for Knowledge, Transformation, Operations, and Revenue — a six-axis CoE blueprint unifying presales, demo engineering, skunkworks, and sales ops under a single governed operating model. Successor to NASA (SoundHound) and the codified APEX framework; authored the Microsoft 365 implementation mapping for OKR-to-execution telemetry.
  • Authored Quant's Enterprise Operating Blueprint (nine-phase customer journey mapped across all four BU quadrants) and the AI Discovery & Qualification toolkit — Opportunity Qualification Framework, Use Case Discovery Guide, Solution Discovery Workbook, BRD templates, and the Strategic Demo Playbook (Engineering Certainty in Enterprise AI Sales).
  • Authored Quant's Value Engineering Framework — the official ROI practice for enterprise AI. Five-formula model anchored to LSE Advocacy Drives Growth research and McKinsey IVR/FCR benchmarks for CFO-grade defensibility.

Agentic AI Architecture & CCaaS Strategy

  • Designed the Agentic Business Lifecycle — operating model extending agentic AI beyond the chatbot: service intent decomposition, workflow orchestration, human-in-the-loop approvals, evidence capture, and closed-loop KPI feedback.
  • Authored Saudia AICC integration strategy and the Voice Streaming Connector platform proposal — dual-track architecture pairing tactical SIP delivery with a streaming-first abstraction across major CCaaS platforms, collapsing per-platform integration from months to weeks.

Platform Engineering & Tooling

  • Built Agent Foundry (open-source) — LangGraph multi-agent harness with supervisor orchestration, channel-aware I/O, governance/PII filtering, OCEAN personality modeling, and HITL escalation; foundation for multi-agent voice orchestration.
  • Built ISIP (open-source) — developer-first SIP automation toolkit on native PJSIP bindings with an MCP server enabling AI assistants to place real outbound voice calls (TTS prompt, Deepgram transcription); planned automation layer for healthcare RCM and DTMF/IVR traversal.

SoundHound AI / Amelia (formerly IPsoft Amelia)

Senior Director, AI for Enterprise & Global Solution Architecture

Healthcare Practice Build

  • Built Amelia's healthcare practice from inception. Closed UMiami Health (first intentional healthcare customer, co-sold) and $17M Visionworks — blueprint replicated across DSO/specialty and vision. Paid engagements at Aspen Dental (TAG), Coast Dental, Eyefinity, and others.
  • Led Epic, Cerner, and Meditech integration engagements — FHIR + HL7-mediated clinical and administrative context for voice and digital workflows; HIPAA/HITECH compliance design.
  • Partnered directly with CIO, CMIO, and CXO leadership across patient access, intake, scheduling, waitlist recovery, no-show recapture, prior authorization, post-visit collections, and workforce coordination.

Global Practice Building & Leadership

  • Founded NASA — scaled 3 → 10 engineers as Director establishing the brand, culture, and operating cadence. Promoted Implementation Engineer → Senior Director across four roles.
  • Scaled to ~50 engineers across four post-acquisition BUs (Enterprise, Restaurants, Automotive, Smart Answering) spanning NA, EMEA, APAC, and LATAM as Sr. Director. Designed the SE operating model end-to-end: hiring, enablement, certification, Communities of Practice, utilization.

Revenue Impact & Enterprise Deployment

  • $50M+ closed enterprise AI deals — $17M Visionworks, $9M competitive displacement (SoCal Edison), $6.25M Chipotle; material contribution at UMiami Health, Wellstar, and Thomson Reuters; principal solutioning on enterprise pursuits at HCA, Sutter, Ochsner, Optum.
  • Led 100+ production deployments across Genesys, NICE, Five9, AWS Connect, custom SIP, EHR, CRM, ITSM, and backend API integrations.

Frameworks, Centers of Excellence & Authorship

  • Delivered three 2025 analyst placements end-to-end — Everest Group PEAK Matrix Leader, IDC MarketScape Leader, Gartner Magic Quadrant™ Visionary in Conversational AI — owning pipeline, briefings, and demos.
  • Authored Architecting Certainty: The Definitive Guide to the High-Stakes Product Demonstration — demo philosophy and presenter playbook (Hero's Journey narrative + eight-pillar framework) operationalizing the Golden Demo Library, POC governance, and analyst-briefing posture across the global SE/SA practice.
  • Compressed time-to-demo from weeks to days. Architected a Domain Intelligence Schema (DIS)–seeded demo generation system converting discovery inputs (vertical, persona, use case) into runnable agent demos and presenter narratives.
  • Authored a 50+ page Presales Transformation Roadmap — full-lifecycle operating model (intake → discovery → demo → scoping → SOW → handoff → POC → sandbox → RFX) with build/buy decisioning per stage and 3-year projected ROI.
  • 38% POC win rate · 114% sales win conversion lift · 40+ hrs/quarter SE prep saved. Built the POC governance and evaluation framework, Golden Demo Library, and APEX Automation Center of Excellence that produced them.
  • Authored Amelia's regulatory compliance reference guide (HIPAA/HITECH, GDPR, EU AI Act, ISO/IEC 42001, NIST AI RMF, BIPA, COAIA + 20 frameworks), the flagship product demonstration on SoundHound's Amelia product page, and the SoundHound voice AI blog feature How Amelia 7's Agentic Framework Unlocks Flexible Automation.
