Bartmoss St Clair
@bartmossstclair
AI leader combining NLP research, product strategy, and team building to deliver scalable AI solutions.
What I'm looking for
I am an AI leader with a strong foundation in mathematics and theoretical physics, over a decade of industry experience, and deep expertise in NLP, ML, and MLOps. I build and scale AI teams, drive product-focused research, and translate complex models into production systems.
As Head of AI I scaled a team from 3 to 10 engineers, moved from third-party models to in-house solutions reducing costs by 10x, improved latency and accuracy, and delivered high-conversion AI-driven paraphrasing features. I have led cross-functional programs, managed AI budget and roadmaps, and developed RAG and other retrieval-based solutions.
I advise startups and enterprises on AI strategy, teach and upskill teams, contribute to open-source projects like Secret Sauce AI, and have worked with organizations such as Samsung, Harman, MSD, Citigroup, and others. I prioritize pragmatic, cost-efficient AI adoption that empowers engineers and leadership to act on data.
