Based in Paris

After 4 years as a financial analyst in investment banking at Société Générale CIB, I transitioned into software engineering by joining École 42 in 2022 and later the Assurly engineering team as a Software Developer. Combining a strong background in finance with modern software architecture, I specialize in building end-to-end digital products — including two AI-powered mobile applications leveraging LLMs, agentic workflows, and cloud backends.

Projects

Miles.ai — application de coaching IA par Valentin Escaffre

AI Coach for Endurance Sports

Mobile app where athletes chat with an AI coach grounded in their own training data. Workouts sync automatically from Apple Health and Health Connect. A serverless AWS backend builds a structured context and orchestrates an LLM with tool calls — web search and route generation — returning interactive blocks: charts, tables, workout cards and maps. Also features on-device analytics (VO₂max estimation, training load, personal-best detection), AI-generated training plans, voice and image input, subscriptions and push notifications.
