I am a dual citizen, including European Union nationality, with solid experience working for European companies. As a computational linguist, I specialize in natural language processing (NLP), artificial intelligence (AI), and speech technologies. At SiDi, I develop cutting-edge Text-to-Speech (TTS) systems for diverse platforms, leveraging expertise in NLP, AI, and speech technologies. By collaborating with cross-functional teams and employing structured data collection and annotation, I refine linguistic models and ensure data quality and diversity across languages and dialects.
With over eight months of computational linguistics experience at SiDi and prior roles in ontology design and sentiment analysis, I contribute to scalable machine learning applications. During my tenure, I designed and optimized prompt templates for generative AI to curate linguistic data for ASR, TTS, and MT; generated and managed multilingual corpora and translations covering diverse registers and dialects; partnered with AI developers as an end-user linguist—iterating on prompts, outputs, and workflows for both commercial and proprietary platforms—and documented prompt-engineering and data-curation guidelines to enable consistent GenAI workflows. Committed to innovation and meticulous process documentation, my work is aligned with client needs, driving advancements in computational linguistics and delivering impactful AI-driven solutions.More...
