Want to integrate AI into your product or automate your business, without hiring a team or losing 6 months in R&D?
I design and deploy custom AI agents, chatbots, and automations for startups and SMEs. From POC to production, solo, in a team, or as a technical lead.
━━━━━━━━━━━━━━━━━━━━━━━━━━━
What I deliver:
→Business AI Agents & Chatbots(customer support, lead qualification, onboarding, conversational coaching…)
→ **AI Workflow Automation**: connect your tools (CRM, Slack, WhatsApp, Notion, APIs) with solutions that run 24/7
→Web & Mobile Applications with Integrated AI(RAG, semantic search, computer vision, content generation, recommendation)
→AI Audit & Roadmapto identify the highest ROI use cases
━━━━━━━━━━━━━━━━━━━━━━━━━━━
What sets me apart:
A graduate of **HEC Lausanne Master's degree**, I founded and built several AI products solo and in a team, from idea to production:
•Yuzu— recipe mobile app, 1800+ users, CHF 35,000 raised
•Calerys(calerys.com) — WhatsApp nutritional coaching AI assistant
•LipoTrack— health app for people with lipedema
I can speak to CTOs and CEOs alike, which accelerates decisions and avoids unnecessary iterations.
