I m a telecommunicatio engineer specialized in embedded software development. I contributed in many embedded software projects as a developer and now I m leading many embedded software projects. I developed network stacks (like TR-069) and customized features for many clients with C, shell, awk,... for linux platforms (like OpenWRT) and VxWorks. I m the maintainer of the open source project EasyCwmp (http://www.easycwmp.org). EasyCwmp is an implementation of the TR-069 cwmp client. And in my knowledge it's the first complete open source of the cwmp client and it's fully conform with the standard TR-069

Focused since 2022 on generative AI. I created MindRoot, an open source plugin-driven agent system with a fully customizable UI. Existing plugins for MindRoot enable knowledgebases, interactive video avatars with text-to-speech, commands that let agents query and update Supabase or MySQL, computer control by the agent, system and Python command execution, image and video generation, long workflows with supervised subtasks, reasoning, and more. I started teaching myself programming around age eight. The last several years mainly focused on backend JavaScript, some TypeScript and Python (also related such as Docker, Postgres, MongoDB, etc.), previous to that front-end JavaScript (some React, Vue.js, Three.js), before that C# (don't do MS anymore), etc. Over the years, some projects with simple C++. Current focus is on my latest AI agent framework.

🥇 Top Rated on Upwork | 5+ Years Delivering Production Systems AI Orchestration • Agentic Systems • AI Ops • Automation Architecture I architect and orchestrate production-grade AI systems. In 2026, writing code is no longer the bottleneck. Orchestration is. My work focuses on designing modular infrastructures where AI agents, automation pipelines, and scalable systems operate reliably, transparently, and under control. I build execution environments where LLMs, vector databases, automation engines, and backend services work together as structured components, not experiments. What I Actually Do • Architect multi-agent AI systems with clear execution boundaries • Design RAG infrastructures with embeddings, retrieval, and evaluation layers • Build AI orchestration pipelines, local or cloud-agnostic • Implement AI Ops workflows including monitoring, logging, evaluation, and rollback strategies • Structure data ingestion pipelines for scraping, parsing, normalization, and indexing • Convert unstructured knowledge into vectorized, queryable systems • Deploy local LLM infrastructures that are GPU-aware, measurable, and self-hosted • Integrate APIs, webhooks, and event-driven architectures • Create deterministic automation flows in Bash and Python where AI acts as an executor • Implement CI/CD and reproducible AI deployment environments • Engineer Linux-first, infrastructure-controlled AI stacks Approach AI writes code. I design the system that determines what AI should build, how it should be deployed, how it should be measured, and how it should recover when things fail. No black-box SaaS dependency. No fragile no-code dashboards. No hype-driven stacks. Modular components. Observable execution. Reproducible deployments. Auditable AI behavior. I Prioritize • Orchestration over raw coding • Measurable inference over demos • Infrastructure over UI polish • Control over abstraction Core Stack (AI-Centric) Python • Bash • FastAPI • Docker • Redis PostgreSQL • Vector Databases (Pinecone, Chroma) OpenAI • Cohere • Local LLMs (GPU / Self-Hosted) Debian Linux • Git • CI/CD • systemd Legacy & Extended Experience PHP (Core, Procedural, Shell-Integrated) Perl (Sysadmin, Automation) JavaScript (Node.js and Browser) HTML/CSS Languages English (Fluent) Portuguese (Brazil & Portugal) Spanish Billing Philosophy Milestone-based delivery. You pay for infrastructure that is delivered, tested, and validated, not for hours consumed. If you need AI systems that actually run in production, not just prompts, let's build them properly.
