A Layered, AI-First Platform Architecture

A layered, distributed reference architecture I designed and built AI-first. Applications and an API layer sit over a model-agnostic agentic runtime and MCP tool mesh, down through advanced RAG, governed data, and MLOps foundations, all on shared platform-engineering infrastructure. Here's the architecture and the pieces I led.

A layered reference architecture: applications, an API & workflow layer, the model-agnostic agentic framework, the data & MLOps foundations, all on shared platform-engineering infrastructure (reference implementation; portable to any cloud).
First principles

How I build platforms

The principles behind every architecture I design, learned across identity, data, and AI at scale.

Build foundations, not features. Identity, data and AI context are the platforms everything else runs on. Get them right and every product on top compounds.
Abstract the heavy lifting. Centralize security, compliance, identity, data and AI so product teams ship differentiation, not plumbing.
Composable by default. Every capability is an independent building block, usable alone or compounded into workflows. Reusable SDKs and golden paths cut the boilerplate.
Model- and vendor-agnostic. Never lock the architecture to one model, cloud or framework; choose per use case and keep the cost of switching near zero.
Ground AI in real systems. AI earns its place only when wired to governed data, retrieval, evaluation and guardrails. The model is the smallest part.
Evolve without disruption. Separate platform from business logic; strangle legacy incrementally and upgrade the stack without breaking delivery.
Ship with discipline. Shift-left security, reusable CI/CD and observability, evaluation and human-in-the-loop review, so AI ships repeatably and responsibly.
Adoption compounds value. The platform shifts from cost center to value multiplier; every new consumer lowers the cost of the next innovation.

Model-Agnostic Agentic AI Framework

A reusable reference framework that lets teams build agents without locking into any one model or orchestrator. Built on Amazon Bedrock AgentCore (Runtime, Identity, Gateway, Memory, Observability) with an AI Agents Studio that plugs into Strands, LangGraph, CrewAI, n8n, Vertex, and OpenAI, fronted by an Orchestrator and an internal Agent Marketplace.

Hub & Spoke MCP Framework

A hub-and-spoke Model Context Protocol layer that turns tools and external systems into discoverable, governed capabilities. AgentCore Gateway handles discovery and invocation against a central Tools Repository, while the MCP layer brokers access to first- and third-party systems: AWS Marketplace, Azure Copilot, and partner platforms.

Advanced RAG

A retrieval layer engineered for accuracy at scale: hybrid retrieval that runs dense vector search and sparse lexical (BM25) together and fuses their rankings with Reciprocal Rank Fusion, then cross-encoder reranking and Maximal Marginal Relevance for relevant, non-redundant context. It runs over an Amazon OpenSearch vector database, with content prepared using Unstructured.io, per-use-case model selection via the Bedrock Model Catalog, and Bedrock Guardrails plus prompt governance keeping answers safe and grounded.

MLOps: Continuous Delivery & Training

An end-to-end MLOps practice with CI/CD and continuous training: automated pipelines for data validation, training, evaluation and registration, continuous delivery to serving, and production monitoring that triggers automated retraining. Agents can create, train and retrieve models through the same pipeline. It also covers model fine-tuning and compression: supervised fine-tuning and teacher-student knowledge distillation to shrink large models into smaller, cheaper, lower-latency students that retain quality for production serving.

Snowflake Medallion Data Platform

The governed data foundation everything draws on: a Snowflake lakehouse on a Bronze to Silver to Gold medallion architecture, transformed with dbt, catalogued and lineage-tracked, and surfaced through a knowledge-graph database for relationship-rich retrieval.

AI-Driven Scraper Architecture

An AI-assisted acquisition pipeline that pulls from many sources: databases, files, PDFs, reports, and the web. It then synthesizes them, infers and generates a schema, and schedules ingestion with AI in the loop. Content is extracted and chunked through Unstructured.io and embedded at scale into the vector store.

AI-DLC Implementation

An AI Development Life Cycle with AI applied at every step, organized as two loops. In the fast inner loop, engineers work in an AI-enabled IDE: scaffolding from golden-path templates, AI pair-programming, and a shift-left approach that pulls tests, security and evals to the moment of authoring. The outer loop covers CI/CD, infrastructure-as-code (AWS CDK + GitHub), evaluation and observability (Langfuse, AgentCore), and production feedback that flows back into the inner loop. The result: AI ships repeatably and responsibly.

Architecture Modernization: DDD, Strangler Fig & Micro-Frontends

A repeatable playbook for converting monoliths to modern systems without a risky big-bang rewrite. Domain-Driven Design carves the monolith into bounded-context microservices; the Strangler Fig pattern routes traffic incrementally from legacy to new services behind a facade until the old system can be retired; and a micro-frontend shell composes independently-deployable UIs per domain.

Composable Platform & Principles

Every capability is an independent, composable building block, usable alone or compounded into complex workflows, rooted in business need. Golden Paths and reusable SDKs abstract the heavy lifting (security, compliance, infra, data, identity) so teams focus on differentiation.

Generative UI & Agentic UX

A persona-aware experience layer with deep UX customization and contextual agents at every layer, from intelligent search and interactive exploration, to drag-and-drop generative widgets, to agent-built dashboards and custom apps on the same governed data platform. The agent-to-UI contract is built on open standards: AG-UI for streaming agent-to-frontend events and generative components, and A2UI for declarative, model-rendered interfaces. Any compliant agent or model can drive the UI without custom glue code.

Agent Studio & Workflow Automation

A unified control plane to build, deploy and orchestrate intelligent agents: one-click agent creation, a tool and connector registry, a visual workflow builder for multi-step orchestration, integrated chat for testing, and embedded SDLC with launch.

Autonomous DevOps Agent

An always-on operations teammate that autonomously investigates incidents and remediates across the stack: alert ingestion, then triage & correlation, then root-cause analysis, then auto-remediation, then a prevention spec, all wired into the observability and alerting stack.
