Product @ LSEG — Analytics & AI

Endurance athlete. Builder. Long-distance thinker.

I simplify complex financial systems, build tools for developers and AI models, and spend a lot of time training for long races.

About Me

I build products at the intersection of AI, analytics, and developer tooling. Right now: leading product for LSEG Analytics & AI, shaping how financial markets are understood by humans and LLMs.

Outside of work, I'm deep into endurance sports — 2× Ironman 70.3 finisher (Valencia, Berlin), multiple marathons (latest 3:08 in Florence), and currently training for 70.3 Venice, the Barcelona Marathon, and my first full Ironman in the Loire Valley.

I like long distances — in products, in training, and in life.

Work @ LSEG

Lead product management for LSEG Analytics & AI

AI for Financial Markets

Building the semantics, ontology, and tooling that let LLMs interpret pricing, analytics, curves, events, and research at scale.

Developer Platforms

APIs, SDKs, runtimes, abstractions — the infrastructure that makes financial data feel clean, fast, and consistent.

Simple Philosophy

Complexity deserves clarity. Products should feel inevitable once they exist.

Endurance & Triathlon

Training is where I reset, rethink, and rebuild. The process is hard, and that's the point — it's the discipline it builds that carries into everything else.

"Only the disciplined ones are free. If you are undisciplined, you are a slave to your moods"

How I Train

Discipline. Passion. Motivation. In that order — because motivation fades, passion is the why, and discipline is the must.

Not a Pro… Technically

I'm not a professional athlete — I just play the part with enthusiasm. My quads are still questioning the casting.

Find the Data

A quiet record of the miles, the early mornings, and the long sessions that shape how I work — patient, structured, data-driven.

Metrica.fit

A personal project shaped by endurance training — built to make the sport simpler, smarter, and more accessible.

AI-Driven Training

Training plans that adapt to real life. Lightweight, personalized guidance powered by AI — without the noise or complexity of traditional platforms.

Free Athlete Tools

A growing set of simple, focused tools for triathletes and runners. Designed to remove friction, improve decisions, and support athletes at any level.

ML Bike Fit Analysis

A computer-vision tool that analyzes your bike fit through video. Built so athletes can ride more comfortably and efficiently — entirely free for the community.

My goal: keep athletes focused on what matters, and give back to the sport that changed me.
