The Mathematics Behind LLM Fine-Tuning: A Beginner's Guide to how and why finetuning works
July 28, 2025
Experienced analytics leader with more than a decade of global experience spanning data and AI, private equity, management consulting, and software engineering.
I enjoy challenges that demand both technical expertise and practical execution. Whether it's scaling distributed systems, applying statistical learning to improve decision-making, or turning cross-disciplinary ideas into products that deliver measurable value, I'm drawn to problems that require real engineering depth. I like getting deep into the code, but I'm just as energized by leading initiatives, driving execution, and collaborating across domains to make things work in the real world.
I've built teams, functions, and companies from the ground up and led analytics-driven initiatives across portfolio and client organizations. My work often sits at the intersection of finance, strategy, and advanced analytics, helping businesses launch and scale new capabilities with purpose.
Over the years, I've worked across the full data and technology spectrum—from software and data engineering to data science, strategy, and investing. This breadth helps me bridge the gap between technical, business, and executive teams, keeping communication clear and aligned. I aim to strike the right balance between quick wins and long-term thinking—whether I'm building scalable platforms or helping teams focus on the 80/20, the goal is the same: make progress that actually moves the needle.
I've lived and worked across North America, Latin America, Asia, and Europe, and currently call Singapore home. Before that, I was based in San Francisco and spent time in cities like Jakarta, Boston, São Paulo, London, Berkeley, Zurich, San Jose, Hong Kong, and Stuttgart. This global exposure has shaped how I lead and collaborate—giving me a grounded sense of how culture, context, and communication styles shape how work actually gets done. Along the way, after nearly 15 years on the go, I've learned how to get things done in unfamiliar settings and stay grounded—even when things are a bit messy or the path forward isn't perfectly clear.
