Architecture & AI Capability Portfolio

Blueprint Gallery

A 6-layer architecture blueprint for the iCertify credential ecosystem, mapping the AI-Augmented Security Engineer master credential, shared capability spine, delivery system, governance framework, and expansion roadmap.


Production-Grade RAG System

A production‑grade Retrieval‑Augmented Generation architecture that integrates hybrid search, cross‑encoder reranking, and automated evaluation to deliver grounded, traceable answers for internal knowledge workflows with consistent quality and governance.


iCertify Architecture Blueprint

A multi‑layer credentialing platform architecture that unifies the AI‑Augmented Security Engineer master credential, capability pathways, delivery workflows, governance controls, and long‑term expansion roadmap into a governed, extensible ecosystem.


Confluence Learning Hub Architecture

A Confluence‑based learning ecosystem architecture that mirrors real delivery workflows and provides a governed, modular foundation for capability development, content lifecycle management, and AI‑augmented learning across engineering and product teams.


DailyDos System Map

A behavior‑design system that applies architectural principles to daily habit formation, demonstrating how human workflows can be structured with the same clarity as technical systems.
