Specialization

Architectural Expertise

Specialization across four classes of complex AI engineering problems where system architecture, data provenance, evaluation, and production constraints determine durability.

Four Pillars

Core Architecture Disciplines

Each pillar addresses a specific problem territory, structural trade-offs, and production constraints.

01

System structure, component boundaries, and reliability

AI Systems Architecture

Architecting system boundaries, model orchestration, and reliability guarantees for complex production AI systems.

Where should the boundaries between probabilistic model logic and deterministic business rules be drawn?
02

Autonomous workflows, orchestration, and state management

AI Agents & Agentic Workflows

Architecting autonomous agent workflows, tool execution boundaries, failure recovery, and verifiable human-in-the-loop controls.

Should the workflow be structured as an open-ended autonomous agent, a directed acyclic graph (DAG), or a strict finite state machine?
03

Retrieval architecture, knowledge provenance, and verification

RAG & Knowledge Systems

Designing enterprise retrieval-augmented generation (RAG), verified source attribution, hybrid search, and retrieval evaluation.

What retrieval strategy fits the corpus: dense embeddings, lexical BM25, hybrid re-ranking, or knowledge graph traversal?
04

Prototype to production, unit economics, and staged rollout

AI Product Engineering

Engineering AI-native products, feasibility validation, latency/cost trade-offs, and staged production rollout.

What is the modeled unit cost per query at 10x and 100x user scale, and can distillation, routing, or semantic caching compress it?
