Jonathan Racaud

@jonathan-racaud

Software engineer specializing in mobile and backend.

I am a software engineer with broad experience across mobile (Swift), backend (C#/.NET) and embedded systems (Arduino, ESP32), focused on building robust, modular cross-platform solutions.

I have developed iOS SDK components, backend data pipelines, and firmware, and I advocate for maintainable architectures and clear documentation that speeds onboarding and collaboration.

Recently I have expanded into AI/ML, working on Retrieval-Augmented Generation (RAG), prompt engineering, and LLM integration, including a public Astro Mind project using Qdrant and Python.

I work in agile teams using Git, Jira and Confluence, and I bring technical rigour, pragmatic design, and a drive to deliver future-ready software that scales across platforms.
