Guilherme Pinheiro
Data & Applied AI Solutions Architect | Data Steward @ Claro Brasil | Founder @ Datano
Sao Paulo, Brazil

About
My professional focus is Data & Applied AI Solutions Architecture: designing data pipelines, integrations and AI-powered automation that connect business requirements to reliable implementations.
Since October 1, 2026, I have been part of the CNX Mobile (CNX Móvel) squad at Claro Brasil as a Data Steward / Data Translation Specialist. My focus is data quality, integrity and traceability: connecting technical information with business needs, documenting definitions and rules, and supporting source reconciliation and validation.
My background in Anti-Fraud, Marketing, Data Engineering and Backend Development shapes how I approach this role. I build pipelines and automation, and help teams understand what the data means and how it supports decisions.
Founder of Datano — a consultancy focused on data solution architecture, data engineering, systems integration and applied AI, using Azure, AWS, Python, SQL and Power BI.
My work combines data governance & quality, AI/LLM agents & MCP tooling, data engineering & ML pipelines, cloud/DevOps & VPS orchestration, Microsoft 365 / SharePoint / Graph API integrations, and network automation (MikroTik, RouterOS, proxies).
Creator of pyaccelerate — a Python acceleration engine with multi-GPU, NPU, IoT, and Kubernetes support — and Animus, a self-hosted AI memory synchronization network.
Currently working on GPU-aware optimization for ollama and contributing to the AI inference ecosystem.

AI & ML Projects
Animus — AI Memory Synchronization Network
Animus is a private, self-hosted memory synchronization network for AI assistants. It collects, indexes, curates, and syncs context across machines through a secured hub:
- Multi-assistant collection: GitHub Copilot Chat and CLI, Claude Code, Antigravity, project instructions, prompts, agent definitions, and curated notes.
- Knowledge retrieval: SQLite FTS5 search across sessions, projects, decisions, and reusable technical context.
- Knowledge OS: Verified material is promoted into a structured Obsidian vault, keeping raw memory separate from curated knowledge.
- Secure synchronization: Signed HTTPS requests, replay protection, peer identity and version visibility through a self-hosted hub.
- Peer lifecycle: Automatic release checks plus idempotent ZIP packages for installation, update, or repair on Linux and Windows.
- MCP and Web: MCP retrieval for compatible assistants and a sanitized Markdown viewer with Mermaid diagram rendering.
The MCP interface makes the network practical day-to-day: assistants can retrieve relevant notes, prior decisions, project conventions, and previous sessions on demand without exposing infrastructure details publicly.
Tech: Python, FastAPI, Pydantic, SQLite FTS5, HTTPS, HMAC-SHA256, Obsidian, Mermaid, Docker, systemd, Windows Task Scheduler, MCP.
Multi-Agent Orchestration Platform
Private platform for coordinating specialist AI squads through reusable workflows, explicit task routing, contextual memory, and Builder/Validator quality gates. Publicly shareable patterns include multi-stage execution, specialist handoffs, and evidence-based validation; agent definitions, infrastructure, and operational data remain private.
NPS Classification Engine
Enterprise feedback classification system for NPS verbatims. It runs an auditable cascade that separates customer feedback from operational boilerplate and classifies each record by product, reason, sub-reason, sentiment, root cause, and recommended action.
| Layer | Technique | Role |
|---|
| 0 | Separator | Extracts customer feedback vs. operator boilerplate |
| 1 | Deterministic rules | Priority regex -- fast and auditable |
| 2 | Custom ML model | TF-IDF (word + char) + ensemble (LogReg + ComplementNB) |
| 3 | Pluggable AI | Low-confidence escalation to LLM (opt-in) |
| -- | Fallback | Manual review when confidence is too low |
Key design decisions:
- Confidence measured as margin between top-2 classes:
top1 / (top1 + top2).
- Multi-scenario architecture:
core/ engine + profiles/ plug-ins; the first profile is verbatim NPS, new domains add new profiles without touching core.
- Status bands:
CLASSIFICADO (≥ 0.90), PENDENTE (0.40–0.90), ANÁLISE_MANUAL (< 0.40).
Tech: Python, scikit-learn, pandas, regex-based rules, pluggable LLM layer.
Repository is private and corporate-bound, so only technical approach and public patterns are shared here.
IRobot-Not
Proprietary desktop ETL workflow orchestrator built from scratch with Java 23 + Swing. It provides a visual, graphical interface for designing, scheduling, and executing data pipelines without relying on enterprise ETL suites.
- Visual pipeline designer: drag-and-drop style workflow composition via Swing UI.
- Multi-source connectivity: JDBC integration with Oracle, SQL Server, PostgreSQL, MySQL, and flat files.
- Execution engine: multi-threaded orchestration with ExecutorService, retry logic, error handling, and execution logging.
- Extensible architecture: plugin-friendly transformation steps and configurable pipeline definitions.
- Observability: real-time execution status, logs, and failure diagnostics directly in the UI.
Tech: Java 23, Swing, JDBC, ExecutorService, JSON/YAML, Maven, Oracle, SQL Server, PostgreSQL, MySQL.
