What I'm looking for

I seek impactful roles building production ML/AI systems, mentoring teams, and driving data-driven strategy in collaborative, growth-focused environments.

I am a Manchester-based Senior Data Scientist and AI specialist with 7+ years delivering production-ready machine learning solutions across the global fintech ecosystem, and an MSc in Artificial Intelligence. I combine applied research in GenAI, RAG, multi-agent systems and deep experience in demand forecasting, automation, and predictive analytics to drive measurable impact, including £2.6M in annual cost savings.

I am a bilingual communicator (English/Portuguese) and technical leader who mentors cross-functional teams, builds data literacy programs at scale, and translates complex technical work into business value. I have led successful initiatives in sustainability, automation, and analytics, and I seek roles where I can continue to deliver production ML systems, drive data-driven decision-making, and grow multidisciplinary teams.
