★ Introduction
About Me
I was born in Leon, a small city in the north of Spain. I graduated with a BSc in Aerospace Engineering at the University of Leon, with minors in both Electronic and Mechanical Engineering. In the last year of my Bachelors, I was awarded with a scholarship to study in the University of Wisconsin Green-Bay (USA), where I graduated with Highest Honors and started developing an interest in the fields of Space and Finance.
Years of experience in top
finance & aerospace companies
Years of higher education in Engineering, AI & Finance
After realising it aligned much better with my long-term career plans and desired skillset, I decided to focus on the financial sector. As of now, I’ve been working for 4+ years as Quant Researcher-Developer at Goldman Sachs and Morgan Stanley, developing multi-asset portfolio strategies and building quantitative models for MS Rates, Credit, Commodities and FX trading desks.
Over these years, I have found great fulfillment in integrating professional endeavors with academia and research. I feel I still have a lot to learn about quantitative finance and investing, therefore in parallel to my full time job I am pursuing a part-time PhD in Artificial Intelligence applied to Asset Price Forecasting and Portfolio Optimization. Also, I’ve developed several personal projects related to Quantitative Finance (see below).
In the next 3 years after my bachelors, I obtained the CFA Level I and completed two Masters of 2 years each: a MSc in Aerospace Engineering at the University of Leon, and a MSc in Space Systems at ISAE-Supaero (France), one of the leading Aerospace universities in Europe.
During that period, apart from my studies I also acquired professional experience in diverse fields across 5 different countries. I did internships as AI Researcher at Drotium, an autonomous driving start-up; as Astrodynamics Mission Analyst at the German Space Agency, optimizing lunar ascending orbits; and as Satellite Control Researcher at Thales, performing statistical analysis in the positioning of EROSS+ satellite. I was also selected by the European Space Agency (ESA) as one of 30 European students to assist the 2020 Space Innovation Workshop.
Aside from finance, I maintain an active lifestyle and a range of intellectual interests. I train daily with weights/cardio and follow almost every sport, specially football, tennis, F1, NBA and NFL. I also played competitive handball in high school (my team won Spanish championship U-14). Apart from sports I enjoy reading, coding, web design, skuba-diving and going to the opera (Bizet’s Carmen is a personal favorite).

Skills
During my first M.Sc. in Aerospace Engineering, I started becoming interested in finance. After a few months learning from different sources, I found the CFA materials and decided to prepare for the CFA I exam on my own. To my surprise, I found more motivation in this endeavor than in any of my university courses. By the time I completed my second M.Sc., I had successfully passed the CFA Level I. After a couple of internships in the Aerospace Industry I realized I wanted to explore a different path. Whether it was the right decision was unbeknownst to me at the time, but I felt compelled to pursue a career in finance –or at least give it a try.
It was in that context when the idea of understanding a long-term view became important to me. I was aware that finance is one of the most competitive fields in the world. I knew top people prepare for years just to have a chance to enter the industry. I knew I wasn’t going to catch these people in a few months, or even in a year or two. I knew it was going to be a marathon. So I sat down and said: “okay, if I want to do this for a living, and I want to be good at it, this is gonna take some thought. What are the fundamentals I need to master in order to catch up and succeed in this industry? What do I need to work on first?”
“The idea of understanding a long-term view became important to me. I knew I wasn’t going to catch up in a year or two. It was going to be a marathon”.
”What are the fundamentals that I need to master to succeed in finance? What do I need to work on first?”
I did a lot of research on the fundamentals of finance — specially quantitative finance, which I felt specially attracted to due to my technical background. I went through the CFA materials, main financial books, syllabus of renowned financial institutions, blogs, scientific articles, and even researched the methods of the greatest investors of all time. I put together a roadmap with all the fundamental skills required to master the field of Quantitative Finance and Investing (detailed below), and elaborated a plan to focus on one single skill at a time.
“If I want to do this for a living, and I want to be good at it, I better give my best shot.
Warren Buffet, Jim Simons... “Can I get to that level?
I don’t know, but let’s find out””
One of the things that captured my attention the most was how hard it is to beat the financial market, and how only a handful of skilled investors (the GOAT mountain of investing: Ben Graham, Jack Bogle, Warren Buffet, Jim Simons…) have managed to do so consistently over long periods of time. “Can I get to that level?” — the most ambitious part of me dared to ask. “I don’t know but, let’s find out”, responded with curiosity my heart.
And ever since then, it has been that curiosity to see how far I can push what has led me down the path of mastering the art of Finance, Investing and Quantitative Research.
I like to think that the field of Quantitative Finance & Investing is the equivalent of a decathlon in athletics. Same as a decathlon is composed of 10 different events that athletes need to master to be competitive at the sport, in Quantitative Finance & Investing there are several disciplines that need to be mastered in order to become an expert in the field.
Below, I present the maps of what I consider are the main domains of Quantitative Finance & Investing, detailing my personal knowledge, skillset and practical experience in each of them:

As "Quant of the Year" Marcos Lopez de Prado states: "Geometric solutions are particularly powerful to solve Finance problems":
"The goal of my research is to forecast financial systems and make optimal decisions under uncertainty. In order to achieve that, I may apply probability theory, inferential statistics, vector spaces, stochastic calculus, etc. However, when possible, I prefer to state a problem Geometrically or Topologically, because it gives me the leverage to comprehend it before committing equations to a paper."
"For example, here is a Geometry work from Ronald Fisher dealing with Karl Pearson 's (Geometry professor at Gresham College) most famous invention: Correlation. Geometry is the right way to think about correlations. And when it comes to understanding complex dynamic systems with logical and hierarchical relationships, Topology is the way to go!"

I am completely self-educated in Finance, a field that first captivated me while studying for the CFA exam during my M.Sc. in Aerospace Engineering. Despite the challenge of balancing both, I found (Quantitative) Finance even more captivating than my uni courses, and ever since then that curiosity to understand and learn more about the topic has only kept growing.
Over the last 5 years I have been combining studies/work with the study of Finance, progressing through the CFA Certification, my PhD in Financial ML, and expanding knowledge through personal research of the topics I find more interesting (fixed income valuation, derivatives pricing, portfolio optimization..). In addition, I’ve taken a hands-on approach and applied the learned theoretical knowledge to personal projects to master the practical side of trading & investing (see my projects in the next tab).
