Architecting Compound AI Systems
& Operations Automation.
I am William Volodarsky — a Forward Deployed AI & Systems Engineer (Fordham CS, Magna Cum Laude). I bridge Compound AI Systems, enterprise operations automation, and domain ontologies with LangGraph, Deterministic Pre-flight Hydration (DPFH), and spatial visual taste to turn probabilistic models into resilient production infrastructure.
LangGraph State Machines, Domain Ontologies & Subgraphs
Zero-cost DPFH directory injection vs chunk fragmentation
HL7 CDA XML, ADB Scraper, Playwright PDF, IMAP OAuth
Multi-axial alignment, LLMOps & LLM-as-a-Judge harnesses
Nexus: The Compound Agentic Personal OS
Replacing single-prompt toy demos with a stateful, local-first compound AI system. Nexus orchestrates health, career, and research workflows across a 500+ node structured domain ontology with zero hallucinated file structures.
DPFH vs. Traditional Vector RAGZero LLM Cost
Side-by-side operational architecture for structured knowledge retrieval.
- •Chunk Fragmentation: Rips markdown tables, frontmatter, and headings into arbitrary 500-token slices.
- •Lost in the Middle: Semantic search retrieves out-of-context chunks without hierarchical awareness.
- •Hallucinated Paths: Generates plausible but nonexistent markdown note links.
- •Zero-Cost Injection: Deterministic Python pre-node injects live disk directory tree into prompt.
- •Whole-Document Reading: Librarian traverses exact notes and structured wiki-links natively.
- •100% Grounded Links: Every citation is a verified, live Obsidian deep link.

12 purpose-built automation pipelines powering Nexus agents.
Longitudinal clinical record synthesis & lab trend tracking.
Android screen capture with multi-scroll OCR deduplication.
Headless Playwright PDF & python-docx with page-fill metric audits.
Asynchronous email ingestion & priority triage pipeline.
12-case golden dataset test runner with JSON scoring reports.
Pre-commit side-by-side file write review in SQLite.
Deterministic article cleaning & atomic Zettelkasten synthesis.
Automated daily briefing audio synthesis via voice models.
Local asynchronous audio capture & thought triage.
Mobile prompt execution with user-ID crypt-security.
500+ node structured Zettelkasten semantic layer with tree navigation.
Zero-knowledge client-side encryption for personal records.

LangGraph Content Router
Deterministic zero-shot classifier matches user intent against domain agents (Health, Career, Email, Librarian). High-confidence matches route directly; complex cross-domain queries dispatch to the Librarian subgraph.
def route_query(state: SwarmState) -> str:
domain = classify_intent(state["messages"][-1].content)
# Returns "career", "email", "librarian", or "general"
return f"enter_{domain}_subgraph"Professional Experience & Execution
Combining rigorous foundation model evaluation with 8 years of operational leadership, business process automation, and mission-critical compliance.
AI Training Fellow
Foundation Model Alignment- Performed iterative resampling with corrective feedback across LLMs and latent diffusion models.
- Evaluated model outputs across multi-axial quality rubrics: factual accuracy, instruction following, safety, and non-deterministic code correctness.
- Identified systematic failure modes (hallucination patterns, lost-in-the-middle context degradation), translating edge cases into actionable fine-tuning constraints.
Co-Owner & Operations Lead
2x Revenue Growth- Identified high-margin product opportunities through sales velocity and competitive data analysis, deploying new product lines and automated supplier workflows that doubled private brand revenue over 18 months.
- Engineered multi-channel international distribution (Amazon, Wholesale, D2C) across US, UK, and EU markets.
- Managed regulatory compliance, international customs logistics, product design, marketing campaigns, and multi-tier supplier negotiations.
Medical Records & Patient Services
100% HIPAA Compliance- Co-managed clinical records for a premier high-volume ophthalmology practice, maintaining 100% HIPAA compliance across document handling, retrieval, and clinical transfers.
- Built interactive tracking spreadsheets and scheduling databases for patient service quality, driving measurable improvements in clinical throughput and reducing retrieval latency.
Education & Academic Honors
Bachelor of Science in Computer Science
Dean's List. Focus on Algorithms, Operating Systems, Database Systems, Artificial Intelligence, and Software Engineering.
Associate of Science in Computer Science
Rigorous foundation in Object-Oriented Programming (Java/C++), Data Structures, and Discrete Mathematics.
Visual Art & Aesthetic Systems
Engineering and visual art share the same root: spatial reasoning, composition, and taste. A curated collection of original physical paintings, digital compositions, and computational studies.

The Philosophy of Creative & Technical Synthesis
Visual art builds acute spatial intuition and composition discipline that directly informs system architectures, modular component design, and UI telemetry clarity.
Skills & Systems Competencies
Strictly production-tested competencies across agent orchestration, backend services, evaluation testbenches, and data pipelines.
