Enterprise AI Architecture Patterns

Three distinct AI architecture patterns across my enterprise portfolio — RAG, agentic workflow automation, and multi-agent autonomous systems.

Pattern used in: Enterprise Knowledge AI Assistant
Document Sources / User Query
Operational documents ingested at index time; natural language query at runtime
Embedding + Vector Search
Amazon Titan Embeddings V2 converts text to vectors; pgvector finds semantic matches
Context Retrieval
Top-K relevant chunks pulled from RDS PostgreSQL with source metadata
Prompt Orchestration
Context, instructions, and safety controls assembled into a structured prompt
LLM Generation
Claude Sonnet via AWS Bedrock generates the grounded response
Grounded Response with Citations
Answer delivered with traceable source document references

Core Principles

01

Retrieval-Grounded Responses

Every answer is grounded in indexed source documents. No hallucinations.

02

Vector Search & Semantic Retrieval

Semantic embeddings surface contextually relevant content beyond keyword matching.

03

Source Citations & Hallucination Reduction

Responses are traceable to originating documents, enabling operator trust and auditability.

Get in Touch

With a foundation in UX design, enterprise systems, and digital product development, I transitioned into AI Solutions Engineering to help organizations move beyond AI experimentation and into practical business adoption.

I specialize in designing and building enterprise AI solutions that transform unstructured information into actionable business intelligence. My work spans Retrieval-Augmented Generation (RAG) systems, AI assistants, agentic workflows, prompt orchestration, enterprise knowledge platforms, and workflow automation.

Recently, I have focused on developing AI-powered operational solutions across energy, healthcare, and financial services environments, leveraging technologies such as AWS Bedrock, Claude, vector databases, Microsoft Copilot Studio, and enterprise automation platforms. My interests sit at the intersection of AI architecture, operational enablement, workflow automation, and responsible AI adoption — building systems that are reliable, grounded, scalable, and designed around real business needs.
