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

| Oct 2023 – Dec 2024 | Senior Marketing Analyst | Process automation, reporting and data solutions for business decisions |
| May 2022 – Oct 2023 | Senior Anti-Fraud Analyst | Fraud-prevention indicators, analysis and operational automation |
Across my previous roles at Claro, I reduced data processing time by 97.22% through workflow redesign and automation, built indicators that supported fraud-prevention decisions, and developed BI dashboards and data environments. I bring that engineering experience to my current work connecting data, technology and business teams.

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:
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.
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.
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:
top1 / (top1 + top2).core/ engine + profiles/ plug-ins; the first profile is verbatim NPS, new domains add new profiles without touching core.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.
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.
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.
