Data Engineer & Automation Specialist @ Claro S.A. | Founder @ Datano
Sao Paulo, Brazil
Founder of Datano — a data engineering & data science consultancy delivering ETL/ELT pipelines, data warehouses, ML solutions, custom dashboards, and API integrations. 50+ projects delivered across Azure (Data Factory, Databricks, Synapse), AWS, Python, SQL, and Power BI.
My work spans five main domains: 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 peer-to-peer memory sync network for AI assistants.
Currently working on GPU-aware optimization for ollama and contributing to the AI inference ecosystem.

Animus is a peer-to-peer memory synchronization network for GitHub Copilot and Claude Code. It collects, indexes, and syncs AI interaction context across machines through a self-hosted hub:
- Collectors: Copilot chat, debug logs, Claude Code transcripts,
copilot-instructions.md,.instructions.md,.prompt.md,.agent.md,/memories/notes, and MCP knowledge graph. - Indexer: Full-text + semantic search (SQLite FTS5 + sentence-transformers).
- Sync: HTTPS/WSS peer-to-peer replication between machines and a VPS hub.
- CLI:
animusentry point for status, sync, and admin operations. - MCP Server: Exposes indexed memories and cross-session context through a Model Context Protocol server, so Copilot, Claude Code, and any MCP-compatible assistant can query past context in real time during a chat.
The MCP interface is what makes Animus practical day-to-day: instead of losing context between sessions or machines, the assistant can ask the memory network for relevant notes, prior decisions, project conventions, and previous chat turns on demand.
Tech: Python, FastAPI, Uvicorn, WebSockets, Pydantic, SQLite FTS5, Rich, Typer, Docker, Nginx, MCP.
Enterprise feedback classification system built for telecom NPS verbatims. It runs an auditable cascade that separates customer feedback from operator noise 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.

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.
Repository is private and proprietary; only the technical approach and public architecture patterns are shared here.
