I am a hybrid product architect, data engineer, and anthropologist based in Brasília, Brazil.

Throughout my decade-long trajectory, I have designed and deployed high-performance technological systems that turn complex, unstructured field realities — traditional community territorial claims, high-level governmental deliberative meetings, and qualitative ethnographies — into actionable, verifiable, and secure digital assets.

This repository hosts my comprehensive curriculum vitae organized across 6 dedicated profiles, fully synchronized and version-controlled in both English (US) and Brazilian Portuguese (PT-BR).

The accompanying ecosystem reflects a 10-year life endeavor encompassing ~8M+ lines of source code, structured documentation, and multimodal assets governed by deterministic, verifiable rules.

• Zero Dynamic Runtimes: Total elimination of legacy Python, FastAPI, uvicorn, PyTorch, and Celery/arq workers.
• Drastic RAM Reduction: Idle memory dropped from ~2.5 GB to ~25 to 35 MB.
• Ultralight Container: Production Docker CUDA image shrank from ~20 GB to ~500 MB.
• Instant Cold Start: Startup time accelerated from ~20 seconds to < 100 milliseconds.
• True Multi-Thread Concurrency: Tokio work-stealing scheduler leveraging all physical cores without Python GIL contention.

Developed to address the critical risks of autonomous coding agents (sycophancy, hallucinated tests, silent regressions, and dependency bloat), StenioSentinel is our open-source static analysis and architectural governance sentinel written in pure Rust 2024.

• Sub-Millisecond Auditing (<1ms to <500ms): Validates whole workspaces and monorepos instantaneously using Rayon multi-threading.
• Mandatory Quality Gate (Rule 0): Zero tolerance for blind commits or suppressed checks (// @ts-ignore, // stenio-ignore, .unwrap() in production Rust).
• Sectorized Scopes:
  • stenio --scope hub: Enforces backend architecture, frontend reactivity, and ADR standards.
  • stenio --scope homelab: Audits network mounts, systemd units, Tailscale topologies, and documentation integrity.
  • stenio --scope vault: Enforces Obsidian YAML metadata, official tag taxonomies (_tags.md), and markdown link validity.
  • stenio --scope all: Comprehensive system-wide multi-subsystem audit.
• Automated Remediation (--fix): Safely resolves formatting, taxonomy anomalies, and structural divergences automatically.

Our infrastructure embodies the principle that cutting-edge AI and data engineering do not require massive corporate cloud expenditures. The Mnemocine Homelab operates as a resilient, encrypted 5-node hybrid topology across local hardware and edge cloud compute:

My career looks non-linear only until you recognize the recurring pattern: Throughout my journey, I have used technology to bridge worlds that rarely speak to one another.

I began in 2017 as an intern and field researcher at the ISPN (Society, Population, and Nature Institute). Deep in the Brazilian Cerrado, conducting ethnographic fieldwork with traditional riverside and quilombola populations, I confronted a staggering reality: official government maps accounted for only 28% of traditional territories. The remaining 72% simply did not exist in the eyes of the state — rendering these communities invisible to basic sanitation, healthcare, and territorial defense.

What I learned in the dust and water — that data is not merely numbers, but living memory, territory, and struggle — led me to co-architect the Tô no Mapa Platform. By placing intuitive spatial mapping tools directly into the hands of indigenous and traditional youth, we helped register over 2,500 communities, creating an official database now integrated directly into the Federal Public Prosecutor's Office (MPF).

At IPAM (Amazon Environmental Research Institute, 2022–2025), I evolved from communications analyst to digital strategist. I spearheaded institutional growth that delivered +143% digital engagement, reached over 2 million people, served as Scrum Master for cross-functional teams, co-directed a science documentary on Amazonian climate extremes, and received a Mercosur Science Journalism Award. Yet, this intense period also brought clarity: managing conventional institutional public relations was not my calling. Burnout arrived hand-in-hand with conviction.

In 2024, I channeled every lesson learned into building Sumænimá — the independent technological venture I had conceived years earlier. My core thesis was clear: Sensitive community and institutional data must never depend on foreign corporate AI clouds.

Since 2025, that vision has been tested at the highest echelons of public deliberation. As the official rapporteur for the National Council of Traditional Peoples and Communities (CNPCT), my platform StênioREC operated inside the Palácio do Planalto, capturing, indexing, and purifying the historic proceedings that culminated in the Land Regularization Decree, inaugurated by Environment Minister Marina Silva.

To sustain this work independently, I constructed the Mnemocine Homelab: five networked nodes running open-source systems, orchestrated through Tailscale and Docker, proving that sovereign local artificial intelligence is both feasible and superior.

Today, I stand as a hybrid: a product architect who thinks like an ethnographer. I translate ambiguous human needs into resilient distributed software, and complex systems architecture into lasting socio-environmental impact.
