Freelancer profile translated to English.
Back to original languageAbout Guilloux
Senior software engineer, specializing in Java/Kotlin backend with Spring Boot, experienced in cloud-native GCP environments.
Fullstack profile with hands-on experience in frontend (Angular, Vue/Nuxt, React) and CI/CD pipelines.
Concrete production experience in AI architectures: design and production of a conversational agent via Google ADK — a real agentic architecture (not a simple chatbot): the agent queries and modifies a database in real-time via function calling, with RAG on Vertex AI / Gemini.
Daily user of GitHub Copilot and Claude Code, integrated into the core development workflow.
Convinced that AI is profoundly redefining the developer profession — not just as a productivity tool, but in the very design of systems — I am actively involved in this transformation and seeking a team that shares this vision.
