About Me

Data & AI Student interested in Software Engineering and new technologies.

Hello! I'm Ethan, a final-year engineering student specializing in Data & AI at ECE Paris, and a builder at heart. I split my time between product, AI engineering, and mobile development, with a strong focus on turning ideas into real, usable products.

Today, I'm the Co-Founder & CTO of Fidjoo, a creative AI platform where children can generate their own animated books. I design the full technical architecture: React Native + Expo, FastAPI microservices, LLM pipelines, Supabase/PostgreSQL, distributed tasks and scalable generation workflows.

Alongside Fidjoo, I work as a freelance software engineer, helping companies build AI-powered products, automate workflows, and ship robust mobile or web applications fast and clean.

Previously, I was the first employee at Vocca AI, a health-tech startup that recently raised €5M. I built internal tools, integrated medical software, developed Python APIs, processed audio data, and contributed to the core AI receptionist able to schedule, modify, or cancel medical appointments.

My background mixes mathematics (statistics, probability, linear algebra), software engineering (React, Python, TypeScript), machine learning, and product mindset. Early in my journey, I also explored finance and management during an exchange in London, and developed several ML projects, including a facial recognition system in MATLAB.

Outside tech, I'm involved in youth programs as a long-time Moadon camp director, and I enjoy music, sports, and discovering new cultures through travel.
