Linguistics & Artificial Intelligence

As a Master in Linguistics, I apply scientific rigor to next-generation Large Language Models (LLMs), bridging semantic and semiotic analysis with frontier computing

Technical Area 1: NLP Engineering & AI Architecture

Language Science Shaping Artificial Intelligence

Leveraging semiotics and formal linguistics as foundational pillars to guide machine learning and deep contextual understanding in LLMs.

"Unlike purely syntactic approaches in computing, I draw upon discourse analysis and generative semantic structures to decode how AI processes context. Currently, my specialized focus centers on Neural Natural Language Processing in Portuguese, advanced data engineering, and vector databases (RAG)—paving the way for the architecture of high-fidelity intelligent agents."

Technical Area 2: Frontier LLM Alignment & Training

Advanced Logical Reasoning & Stress-Testing

Developing deep intelligence in generative models by challenging the logical consistency of state-of-the-art AI systems.

"Direct involvement in competitive environments and blind evaluations. By crafting highly complex, multi-turn scenarios, I apply weakness tagging to precisely diagnose structural flaws, logical contradictions, and context loss in AI models before they reach the market."

Technical Area 3: Linguistic Data Engineering & Global Quality

Discourse Architecture & Hallucination Mitigation

Applying linguistic science to refine naturalness, mitigating problematic semantic nuances and structuring clean responses for global projects.

"In large-scale projects, I focus on fine semantic refinement and ambiguity elimination, ensuring that models generate responses with high contextual fidelity, free from semantic drift or hallucinations."

Technical Area 4: AI Integration in Content Strategy

Intelligent Automation & Ethical Editorial Workflows

Translating AI training theory into operational efficiency within daily communications and editorial team management.

"I do not merely train external models; I integrate state-of-the-art AI into my strategic ecosystem. I leverage Google Workspace tools and NotebookLM for accelerated market research and Search Generative Experience (SGE), while designing and leading ethical AI training for writers—ensuring business scalability without compromising human authority or authorship."

OFFICIAL CERTIFICATIONS

Google AI Professional Certificate

Holders of this certificate have completed seven courses demonstrating the ability to apply AI across key domains transforming modern work: brainstorming, research, communication, content creation, data analysis, and coding.

Global MOOC on the Ethics of AI

Grounded in UNESCO's Recommendation, this program covers foundational ethical principles, impact assessment, and real-world decision-making—culminating in the design of ethical, human-centered responses across the entire AI lifecycle.
