Engineering the Future of
Veteran Intelligence
S.E.N.T.I.N.E.L S.Y.X is a purpose-built AI platform delivering 95%+ accuracy on veteran services queries through a custom 13B-parameter transformer, enterprise-grade microservices architecture, and HIPAA-compliant infrastructure. Built and managed as a Sr. TPM deliverable with full P&L ownership.
Sr. TPM Delivery Metrics
Quantifiable impact across engineering velocity, system reliability, and business outcomes.
AI Technical Program Manager / Architect
Visionary AI Technical Architect with 20+ years architecting secure, scalable enterprise AI systems. Full technical vision from ideation to production.
Led end-to-end design, development, and deployment of S.E.N.T.I.N.E.L S.Y.X — a production-grade 13B-parameter custom LLM veteran case management platform (95%+ domain accuracy, HIPAA/VA compliant). Expert in full-stack AI architecture: data pipelines, model training, microservices, React/Node.js full-stack, Kubernetes orchestration, agentic systems, and swarm intelligence. Delivered zero-downtime migrations, sub-2s inference, and multi-stage safety validation while managing distributed teams and full technical vision from ideation to production.
The 5 W's of S.E.N.T.I.N.E.L S.Y.X
Every Sr. TPM decision mapped to intent, audience, scope, timeline, and delivery mechanism.
Secondary: VSOs (500+ partner orgs), employers with veteran ERGs, VA-accredited attorneys, investors in govtech
Protected: Active-duty transitioning, disabled veterans with PTSD/TBI, elderly veterans (65+), homeless veteran cohorts
Capabilities: Eligibility assessment, evidence capture, nexus letter generation, appeals workflow, C&P exam prep, benefits tracking
Differentiator: 95%+ domain accuracy vs. 60-70% for general-purpose LLMs on VA regulations
Phase 2: Auth Migration (Weeks 3-4) — JWT/OAuth2, RBAC
Phase 3: Data Layer (Weeks 5-6) — Sequelize, PostgreSQL
Phase 4: API Endpoints (Weeks 7-8) — REST, validation
Phase 5: AI Integration (Weeks 9-10) — LLM wiring, load testing
Data Residency: U.S.-based PostgreSQL HA cluster with FIPS 140-2 encryption
Channels: Web SPA (React), Mobile (Capacitor iOS/Android), Desktop (Electron), Tablet (PWA)
Compliance Zone: HIPAA, VA Security Directive 6500, SOC 2 Type II (Q3 2026)
TAM: $4.2B veteran legal services market growing 8.4% YoY
Revenue Model: $499 Lifetime tier (current), SaaS subscription for VSOs ($2K-$5K/yr), B2B employer licensing
Impact: Democratize access to VA benefits expertise at 1/20th the cost of traditional legal support
Five-Layer Architecture
Independently scalable layers with isolated fault domains, zero-downtime CI/CD, and horizontal scaling capability.
