LOUIS
of the MAHL BROTHERS

PARIS, FR WED, MAY 20, 2026 ENGINEER · TEACHER · BUILDER

Software engineer, part-time teacher, and serial side-project guy with a long-running soft spot for anime, manga, and pretty much anything coming out of East Asia. Studied at ECE Paris, lived a few months in Korea right after, and since then has done time at Thales, in the BI team at Dior Couture, and helped build the data pipelines and front-end at RETCO.ai alongside his brother. Later founded AutoCertif, a self-certification platform for renovation pictures used in state-backed home renovation schemes, where the person paying for the work is often not the one benefiting from it. Now holds a day job at Allianz Partners and runs Alpha Brain on the side, a project fed by the investment communities he reads a little too closely.

Minimalist black-and-white sketch of Louis Mahl
dear reader (and in fact, dear friend), grew up watching one piece marathons and pretty much every science fiction series the early 2000s could throw at a kid, which probably explains a few things. ended up doing engineering at ece paris, spent a few months living in korea right after, and since then i have been splitting my time between teaching at my old school, helping build things on the side, and a day job that keeps me busy. tennis when the weather allows, a little tuning on the car when it does not, manga in the evenings, and a steady diet of investment threads i probably read too much of. love, louis (from online)
