🧠 Signal Stack

“A portfolio of systems — real, independent, and enterprise-grade — where architecture meets execution.”

The Signal Stack is my deep lab: a space for enterprise case studies, independent platforms, and fictional prototypes.
Here, I document lifecycles, architectural frameworks, and governance models — blending TOGAF, LeanIX, and product strategy into practice.

🚀 Enterprise Case Studies

📑 EU VAT Compliance Engine

A blockchain-powered VAT compliance system ensuring proof of delivery across EU borders.

• Architecture Lens (TOGAF/LeanIX)
  • Business: Compliance reporting, fraud reduction
  • Application: ERP integration (mock SAP flows)
  • Data: Delivery evidence, digital signatures
  • Technology: Blockchain receipts, API gateway
• Outcome
  → Reduced VAT fraud by >80%
  → Recognized at European Tax Summit

📡 Telecom Reconciliation Platform

Settlement engine for roaming operators, processing billions of CDRs.

TOGAF Lifecycle

1. Conceive
   • Problem: Months-long roaming settlement with high OPEX + disputes.
   • Vision: Automate reconciliation via blockchain auditability + AI anomaly detection.
2. Plan
   • Stakeholders: Telcos, regulators, roaming teams
   • LeanIX: Application portfolio — legacy mediation vs. reconciliation modules
   • ArchiMate: Technology + Data flow diagrams
3. Develop
   • Stack: Hedera Hashgraph · Hyperledger Fabric · Python anomaly engine · Postgres
   • Architecture: AI detects mismatches → blockchain logs receipts → smart contracts calculate settlements.
4. Qualify
   • KPIs: OPEX reduction %, dispute resolution time, % reconciled automatically
   • OKR Example: “Reduce dispute resolution time from 60 days → <15 days by Q2.”
5. Launch
   • Piloted in multi-operator roaming environment
   • Integrated via OSS/BSS APIs
6. Maximize
   • Added compliance dashboards for regulators
   • LeanIX risk dashboards for blockchain upgrades + AI drift
7. Retire
   • Archive reconciliation history in distributed storage
   • Regulator-facing lineage proofs

Value

• OPEX reduced ~60%
• Dispute cycles shortened by ~30%
• Clear alignment with TOGAF Technology & Data Architecture layers
• Demonstrates use of LeanIX for portfolio & risk governance

---

💱 Stablecoin Payment Platform

Cross-border settlement rails using stablecoins.

• Atomic swaps, liquidity pools, compliance modules
• Outcome: Piloted with regulated institutions; counterparty risk eliminated

---

🌍 Renewable Energy Infrastructure (REI)

Traceability for renewable energy certificates.

• IoT + blockchain for carbon credit validation
• Outcome: Regulators + buyers gain verifiable provenance

---

🌱 Independent Platforms

These projects represent my personal exploration of system design, governance, and scale.

🔐 Neuralic – AI Governance & Explainability

TOGAF Lifecycle

1. Conceive
   • Problem: AI adoption lacks audit trails + explainability
   • Vision: Governance stack that makes AI traceable, explainable, regulator-ready
2. Plan
   • Stakeholders: CIOs, compliance officers, AI leads
   • LeanIX: Map AI services across portfolios
   • ArchiMate: Business → Application → Data flows
3. Develop
   • Stack: Modular services (Neuralic.Core, Neuralic.Trace, Neuralic.Engine)
   • Architecture: Policy store, lineage tracker, explainability layer
   • Security: RBAC, encrypted audit logs, zero-trust APIs
4. Qualify
   • KPIs: % of decisions logged, % explainable models, compliance coverage
   • OKR Example: “Achieve 100% AI lineage tracking across enterprise ML pipelines by Q4.”
5. Launch
   • MVP open-sourced under SignalBuilds
   • Policy templates + governance docs published
6. Maximize
   • Cloud integrations (Azure OpenAI, AWS Sagemaker)
   • LeanIX dashboards for model drift + risk mapping
7. Retire
   • Archive explainability logs
   • Generate governance playbooks for successor AI systems

Value

• AI treated as auditable infrastructure
• Bridges TOGAF IS Architecture with LeanIX governance
• Independent flagship initiative demonstrating trust-first design
