Back to original languageAbout Clément
AI Engineer for mobile-first products — I help founders, CTOs, and product teams design AI features from idea to production.
10 years of mobile development, two co-founded startups, and a genuine product, UX, and back-end culture. I design reliable AI systems that live within a real user journey.
What I can do for you
→ **AI Agents**: design of autonomous agents: OpenAI/Claude API, Google ADK, MCP, orchestration
→RAGPipelines: your data, actionable by AI. Vector databases, chunking, re-ranking.
→ Evaluation Frameworks: benchmarking, prompt **eval**, logs, and observability for reliable models
→ Back-end: Python FastAPI **API**, PostgreSQL, AWS, Firebase, Node.js
→ Mobile Integration: iOS, Android, Flutter, SwiftUI, in-app journeys, and mobile constraints.
→ AI Product & **UX**: use case framing, prototyping, architecture, roadmap, success criteria, and impact measurement.
Experience and Portfolio
I've worked with LCL (bank), Dream Energy (EV charging, Stripe), heypster (GIFs, Apple Watch, Apple Vision Pro), and about a dozen other projects.
I've also designed my own apps: Leafty (sustainable tourism), Rheaparks (hiking, maps), and Mediary (RAG, Agent Skills).
How I work
Co-founding two startups has been a rich learning experience. I know what it's like to prioritize with a limited budget, design a solid V1, and make the right technical decisions from the start to avoid paying for them later.
→ AI Audit: UX, Architecture, and Proof of Concept
→ Short Sprints: deliveries every two weeks — you maintain clear visibility on progress.
→ Mastery of Claude Code, Codex, and harnessing to deliver faster, without compromising quality
→ Clean, tested, and easily maintainable code that you own.
Describe your project in a few lines, I'll respond within 12 hours.
