Why I'm building this in public
A short note on why I started writing here, and what to expect on this blog going forward.
Credit quantitative strategist, London
I build pricing and risk models by day, and write about markets, code, and careers on the side.
I'm Jehoiakim — a quant working in fixed income and credit markets, originally trained in mathematics and computer science in France. This site is where I share what I'm learning, take on the occasional consulting project, and keep a public record of the things I build.
What I do
Quantitative strategy
My day job: pricing, risk, and portfolio optimisation for credit and fixed income desks — from index quoting models to structured financing analytics.
Consulting, on the side
I take on a small number of independent projects in data-driven forecasting and automation, helping businesses replace guesswork with proper models. Get in touch.
Writing & teaching
I write about quantitative finance, career transitions, and the odd bilingual perspective. I also founded Studies and Careers, a YouTube project for students.
