ABOUT

Bridging intelligence
with autonomy.

I architect and build, multi-agent orchestration, and enterprise data intelligence. My work spans the full stack of AI-native engineering , from context management and intent traceability inside developer tooling, to autonomous agent swarms, document intelligence pipelines, and the event-sourcing infrastructure that makes AI decisions auditable at enterprise scale.

Project Chimera

Project Chimera

AI Influencer Network Architecture. Architected an autonomous influencer fleet — persistent, goal-directed AI agents capable of perception, reasoning, creative expression, and on-chain economic agency. Each agent operates with its own crypto wallet, P&L, and brand persona inside a Fractal Orchestration model where a single operator manages thousands of virtual influencers.

System Architecture & Engineering Highlights

Fractal Orchestration pattern: one human managing thousands of autonomous agents via Manager Agent tiers

Model Context Protocol (MCP) as the universal connectivity layer — decoupling agent logic from 3rd-party API specifics

Swarm Architecture with Planner / Worker / Judge roles and Optimistic Concurrency Control

Coinbase AgentKit integration — agents hold non-custodial wallets and execute autonomous on-chain transactions

Self-healing workflows with automated triage agents and Human-in-the-Loop escalation gates

BoardKit governance pattern: fleet-wide policy propagation from a single AGENTS.md config

Multi-tenant data isolation across Digital Talent Agency and PaaS business models

Enhance - Roo Code VS Code Extension

Intent-Code Traceability Engine. Enhancing an open-source AI coding agent (Roo Code) into a governed AI-Native IDE by injecting a deterministic Hook System. Every agent action is cryptographically linked to a business intent — solving the fundamental governance gap where Git sees 50 text diffs but cannot distinguish a semantic refactor from a feature addition.

Governance & AST Engineering Highlights

Two-stage state machine: agent must 'checkout' a formal intent before writing a single line of code

Pre/Post Hook Middleware intercepting all tool executions with strict privilege separation

AI-Native Git layer linking Business Intent → Code AST → Agent Action via SHA-256 content hashes

Intent-AST correlation that mathematically distinguishes AST_REFACTOR from INTENT_EVOLUTION

Parallel orchestration with optimistic locking — prevents silent overwrites across concurrent agent sessions

Living documentation auto-updated as a side-effect of code changes, eliminating cognitive debt

The Automaton Auditor

The Automaton Auditor

Deep LangGraph Governance Swarm. Built a Digital Courtroom — a hierarchical LangGraph swarm that autonomously audits code repositories with the rigor of a forensic investigation. Detective agents gather irrefutable evidence; Prosecutor, Defense, and Tech Lead judges debate it in parallel; a Chief Justice renders a verdict using deterministic rules that override LLM opinion when evidence contradicts it.

Forensic AI & Swarm Dynamics

Hierarchical swarm: Detective Layer (fact collection) → Judge Layer (dialectical debate) → Chief Justice (synthesis)

AST-level forensic analysis — not regex matching, but structural code understanding via Python ast module

Three adversarial judge personas with genuinely conflicting system prompts prevent 'Persona Collusion'

Chief Justice implements hardcoded Rule of Security, Rule of Evidence, Rule of Functionality — LLM opinion cannot override facts

Score variance > 2 triggers automated re-evaluation before final verdict

MinMax optimization loop: peer agents audit your work; your agent improves from their findings

The Document Intelligence Refinery

The Document Intelligence Refinery

Enterprise Unstructured Data Pipeline. Engineered a production-grade agentic pipeline that ingests heterogeneous enterprise documents — PDFs, Excel, Word, scanned images — and emits structured, spatially-indexed, queryable knowledge. Solves the three enterprise failure modes: Structure Collapse, Context Poverty, and Provenance Blindness.

Pipeline & Provenance Engineering

Classification-aware triage agent routes documents to fast text extraction vs. expensive vision model analysis

Structure-preserving extraction maintaining table integrity, multi-column layouts, and formula recognition

Semantic chunking engine that respects logical units — never severs a table from its caption

Spatial provenance index: every extracted fact carries an exact page and bounding-box reference

RAG-ready vector store output with SQL-queryable fact tables for enterprise BI integration

Degrades gracefully: escalates from MinerU → Docling → vision model only when necessary

The Brownfield Cartographer

The Brownfield Cartographer

Codebase Intelligence for FDE Onboarding. A multi-agent codebase intelligence system that ingests any GitHub repository and produces a living, queryable knowledge graph of the system's architecture, data flows, and semantic structure — solving Navigation Blindness, Contextual Amnesia, Dependency Opacity, and Silent Debt.

Static Analysis & Knowledge Engineering

tree-sitter AST parsing across polyglot stacks: Python, SQL, YAML, Jupyter notebooks

Full data lineage DAG: traces data from source tables to outputs crossing Python, SQL, and config boundaries

Semantic index: every function and class carries an LLM-generated purpose description grounded in actual code

Dead code detection and critical path identification in 800,000+ line production systems

CODEBASE.md living context file — injectable into any AI agent for instant architectural awareness

The Ledger

The Ledger

Agentic Event Store & Enterprise Audit Infrastructure. Built the governance backbone for production multi-agent AI systems. An append-only event store that makes every AI decision auditable, reproducible, and cryptographically verifiable — providing the immutable memory infrastructure that prior agent systems lacked and that enterprise compliance teams require before any AI system reaches production.

Event Sourcing & Audit Infrastructure

Append-only event schema with stream partitioning, hot/cold storage, and PostgreSQL LISTEN/NOTIFY

CQRS separation: command handlers enforce business rules; query handlers power read models and projections

Optimistic concurrency control with version-based conflict detection and automated retry strategies

Cryptographic audit chains — hash-chained event sequences for tamper detection and regulatory packages

Async projection daemon with checkpoint management and projection lag measurement

MCP command/resource architecture exposing the store to LLM consumers as a typed, queryable API

The Data Contract Enforcer

The Data Contract Enforcer

Schema Integrity & Lineage Attribution System. Turned every data dependency between systems into a formal, machine-checked promise. When a contract is broken — by a schema change, type drift, or statistical shift — the Enforcer traces it to the exact commit and produces a blast radius report showing every downstream system affected. Built across a live 6-system platform, each system already carrying weeks of accumulated inter-system data flow.

Data Reliability & Contracts

Bitol Open Data Contract Standard implementation with dbt schema.yml and JSON Schema draft-07 validation

Statistical profiling engine detecting distribution shifts, outlier drift, and column-level cardinality changes

Backward/forward/full compatibility model with breaking-change detection before deployment

Git-blame violation attribution — every broken contract traced to the commit and author that caused it

Blast radius report: automated impact analysis of every downstream system affected by a schema change
