About Chloé

QA Engineer with strong technical and product expertise, I combine a rigorous approach from scientific research (PhD in astrophysics, NASA, Columbia) with comprehensive software development and architecture experience as CTO and founder of BavAR[t], a mobile augmented reality application designed from A to Z (backend, API, Unity frontend, UX).

I currently work to improve the quality, robustness, and user experience of applications, particularly on complex products (mobile, Unity, 3D, data).

My approach to QA is holistic: I don't just identify bugs, I analyze systems in depth to understand their origin, impact, and propose concrete solutions.

🔍 My areas of intervention:
• Functional and exploratory testing (mobile, web, Unity)
• Technical QA (API, business logic, data, performance)
• UX analysis and user journey optimization
• Product quality audit (functional, technical, experience)
• Reproduction and diagnosis of complex bugs
• Acceptance testing before production release

🎮 Specialties:
• Mobile applications (Android / iOS)
• Unity, 3D, augmented reality
• Interactive products and immersive experiences
• Systems involving data, calculations, or complex logic

💡 What I bring:
• A complete product vision (tech + UX + real usage)
• An ability to detect complex and invisible issues
• Smooth communication between technical and business teams

🎯 Goal: improve the quality perceived by the user, not just fix bugs.
