About David
I believe AI systems should think, not just respond. That distinction drives everything I build.
For 10+ years I have researched Machine Learning and artificial consciousness. For 25+ years I have engineered software that ships. Today I work at the frontier of LLMs, MCP architecture, and autonomous agents, from Barcelona, for clients across Europe, the Americas, and beyond.
I created three proprietary AI frameworks, published on GitHub (davccavalcante) and Hugging Face:
→ MAIC™ (Massive Artificial Intelligence Consciousness) — large-scale architecture for emergent self-awareness, grounded in Integrated Information Theory and Global Workspace Theory.
→ HIM™ (Hybrid Intelligence Model) — fine-tuned model with a three-pillar architecture (Teleology, Semiotics, Pantheism), benchmarked against Grok 4, Claude Opus, and Gemini 3.
→ NHE™ (Non-Human Entity) — governance specification for autonomous cognitive entities in enterprise AI ecosystems. ISO/IEC 42001 compliant.
Research indexed on PhilPapers (2024, 2025).
In practice, I:
— Fine-tune LLMs using LoRA, QLoRA, DPO and RLHF across Grok 4, Gemini 3, Claude Sonnet/Opus, Llama 3, and DeepSeek R1/R2
— Design and build MCP Servers for LLM tool integration and agentic orchestration
— Implement advanced retrieval beyond RAG: GraphRAG, HyDE, RAPTOR, Self-RAG, ColBERT, Knowledge Graphs
— Architect LLMOps pipelines with MLflow, Databricks, W&B, vLLM, and Ray Serve
— Deploy Computer Vision in production: facial analysis in retail, barcode detection via camera, OCR logistics
— Ensure EU AI Act, RGPD, and ISO/IEC 42001 compliance in every AI system I ship
Previously delivered projects for Google, Facebook, Banco Bradesco SA, Universal Music, Nestlé, Privalia, and Caesar Park — achieving outcomes like 300% growth in qualified leads and 70%+ reduction in content production time through AI automation.
Open to LLM Engineer, AI/ML Engineer, LLMOps Architect, and AI Research roles in Spain and Europe.
