Elyon
47-tool agentic execution layer with RBAC-scoped tools and deterministic contract bypasses.
Architected an intelligent workforce platform that automates HR, contracts, recruitment, and time tracking. It bridges natural language intent with strict business logic via WhatsApp-first workflows.
Architecture Highlights
- 47-tool agentic execution layer
- Modular context loading
- RBAC-scoped AI tools
- Deterministic contract bypass
Tech Stack
Deployed on
Why It Matters
Demonstrates production AI orchestration with clear execution boundaries: the AI can operate real workflows, while critical state transitions remain deterministic.
Hello Paco
Tenant-scoped RAG via pgvector with seamless omnichannel WhatsApp orchestration.
Engineered a unified inbox spanning WhatsApp, Instagram, email, and web chat. Features real-time messaging, AI classification, and robust white-label SaaS billing architecture via Asaas.
Architecture Highlights
- Tenant-scoped RAG (pgvector)
- PostgreSQL Row-Level Security
- Omnichannel messaging
- White-label architecture
Tech Stack
Deployed on
Why It Matters
Proves ability to combine tenant-isolated AI retrieval, real-time communication, SaaS billing, and production-grade support workflows in one platform.
Legendários / Rotabusiness
OpenAI Vision validation, gamification engine, and marketplace logic.
Built a multi-tenant community structure that validates offline engagement via AI Vision, seamlessly integrating marketplace capabilities, Stripe billing, and white-label readiness.
Architecture Highlights
- OpenAI Vision validation
- Gamification engine
- Marketplace logic
- Stripe billing integration
Tech Stack
Deployed on
Why It Matters
Shows practical AI applied to real-world validation and anti-abuse workflows, not just text generation.
Designed an institutional communication platform focused on governance controls. Built around strict PostgreSQL RLS, it safely orchestrates billing workflows via Asaas, WhatsApp messaging, and institutional structures.
Architecture Highlights
- Advanced RBAC
- Secure impersonation
- PostgreSQL RLS
- Institutional workflows
Tech Stack

Why It Matters
Highlights governance-first architecture where permissions, delegation, communication control, and tenant isolation are core system primitives.

Architecture Patterns I Build
"I design applied AI systems with clear execution boundaries, tenant-aware data access, and deterministic fallbacks where reliability matters."
My recent systems are not healthcare products, but they solve adjacent architectural problems: tenant isolation, role-based access, audit-aware workflows, sensitive document handling, deterministic fallbacks, and secure communication orchestration.
PostgreSQL Row-Level Security
Pushing isolation to the database layer. Enforcing tenant boundaries inherently to eliminate application-level data leakage risks.
Agentic Tool-Calling
Designing agents with strict RBAC constraints, allowing LLMs to interact safely with real business databases.
Tenant-Scoped RAG
Utilizing pgvector paired with RLS to ensure embeddings and vector searches are strictly isolated and compliant per tenant.
Deterministic AI Boundaries
Applying LLMs for orchestration, but bypassing them for critical state transitions to guarantee predictability.
Multi-tenant from Day One
Building scalable foundations that inherently support white-labeling, custom billing, and modular configurations.
Real-time Orchestration
Orchestrating stateful, human-in-the-loop communication workflows via WhatsApp APIs, webhooks, and queues.
