When your operations are running blind, every day costs you money. I help manufacturing and operations companies build the data systems that give leadership real visibility — so problems get caught early, decisions get made faster, and KPIs actually drive behavior. What makes me different: I've sat in your chair. As a Shift Manager I led 100+ person teams. As a Process Improvement Manager I reduced production stoppages by 85%. As a Project Manager I delivered $1M+ in savings. I know which questions to ask because I've lived the problems you're trying to solve. As a dropshipping E-commerce operations manager I built multi-channel sales reporting from scratch — ingesting Amazon Seller Central data, allocating courier and channel info, and calculating profits and operational kpis. Improved profit in 32%, refunds recovery in 41+% and reduced order defect rate by 37% with data/process improvements. What I build: • Power BI dashboards that support real decisions (not just display data) • KPI frameworks that align teams to measurable results • Real-time operations monitoring systems • Process improvement roadmaps with clear ROI My stack: Power BI · SQL · M · DAX · PowerQuery · RLS · dbt · Python API integration · GitHub · M365 · ERP · Syspro · Excel · Google Sheets Credentials: · Power BI Associate · WCM International Auditor · Lean Office Consultant · Master's in Automotive Engineering (Politecnico di Torino) · Mechatronics Engineer Most consultants ask "what dashboard do you want?" — I ask "what problem are you trying to solve?" Then I diagnose root causes, develop the right KPIs, and build systems your team will actually use. 📧 Let's talk about what's possible with your data.

A seasoned Quality professional and Team Leader, I operate at the critical intersection of AI development and AI security. My career is dedicated to ensuring AI robustness from two angles: elevating quality standards through rigorous GQA and auditing, and hardening model safety through advanced Red Teaming and adversarial testing. I specialize in closing the gap between an LLM's potential and its real-world performance. By meticulously training and auditing models—while simultaneously challenging them with culturally-specific adversarial prompts—I ensure they are not only accurate and intelligent but also safe and resilient. My deep expertise in the Portuguese language and Brazilian cultural nuances is critical for this dual approach. My Core Areas of Focus: 🤖 AI Quality & LLM Training: I train, audit, and enhance LLMs and Generative AI systems to ensure their outputs are safe, accurate, and contextually relevant. I excel at creating high-quality datasets and providing the critical, nuanced feedback that drives model improvement and fine-tuning. 🛡️ AI Safety & Red Teaming: I proactively identify model vulnerabilities through systematic Red Teaming. This involves engineering sophisticated adversarial prompts and jailbreak techniques to stress-test AI safety guardrails, ensuring models are resilient against manipulation, misuse, and ethical breaches. 👥 Leadership & Team Development: As a Team Lead, I empower quality and data annotation teams to excel in a fast-paced AI environment. I serve as the go-to expert for complex policy cases, mentor rising talent, and instill a culture where meticulous quality and security awareness are paramount. 📈 Data-Driven Process Optimization: I leverage insights from human and AI-generated data to identify bottlenecks, streamline quality assurance workflows, and drive operational efficiency in large-scale data annotation and model review projects. I am passionate about building smarter, safer, and more ethical AI. If you're looking for a professional who understands how to both build quality from the ground up and fortify it against sophisticated threats, let's connect! Specialties AI Safety, Red Teaming, Adversarial Testing, Jailbreaking, Trust & Safety (T&S), Quality Assurance (GQA), Large Language Models (LLMs), Generative AI, AI Training, Team Leadership, Data Annotation, Portuguese Linguistics, Vulnerability Assessment, Process Optimization, Fine-Tuning.

Most AI translations sound correct in Portuguese. That’s exactly why they fail. I help international companies localize SaaS products, apps, websites and AI-generated content for the Brazilian market with language that feels natural, trustworthy and conversion-oriented. My work combines Brazilian Portuguese localization, AI translation review, cultural adaptation and messaging refinement to help companies avoid the common mistakes that reduce engagement, retention and user trust in Brazil. Over the past years, I’ve worked with international companies across SaaS, technology, education, apps and digital platforms, supporting both large-scale localization projects and ongoing product updates. I’m a native Brazilian Portuguese specialist with a background in language, localization and Brazilian consumer behavior. Areas I support most often: ✔ Brazilian Portuguese localization for SaaS and apps ✔ AI-generated translation review and refinement ✔ Localization QA and terminology consistency ✔ Website and product localization ✔ UX language adaptation for Brazilian users ✔ App Store and Google Play localization ✔ Brazilian market language adaptation ✔ Ongoing localization support for growing platforms What clients usually value in my work: • Natural Brazilian Portuguese that does not sound translated • Consistency across products and updates • Fast communication and reliable delivery • Ability to identify cultural and UX language issues early • Long-term support for evolving products My workflow is structured for scalability and consistency, which allows me to support both ongoing projects and high-volume localization demands without compromising quality. If you are looking for Brazilian Portuguese localization that goes beyond literal translation and actually works for Brazilian users, feel free to reach out.
