About François

👋 I am François, a passionate senior developer, Tech Lead, and entrepreneur, with over 20 years of experience in creating innovative digital solutions. My mission: to build robust, high-performing, and user-centric tech products.

🎯 As a Full Stack development expert, I master Java and JavaScript and their key frameworks (Spring Boot, React, VueJS, Node.js...). I work across the entire application chain: design, architecture, implementation, and performance optimization. I am also comfortable with relational databases (PostgreSQL, MySQL) and NoSQL (MongoDB, ElasticSearch).

🚀 As a Tech Lead, I have led agile teams in complex environments (trading ERP, public sector, banking-finance, transport). I drive technical choices, implement best practices (CI/CD, Docker, automated testing), and support team skill development through active and participatory mentoring.

🌟 Founder of the innovative dating app (on iOS and Android) KONOYO, I designed a product integrating neuroscience, embedded AI, and gamification. This venture allowed me to acquire in-depth expertise in product strategy, digital marketing, GDPR, monetization, and crowdfunding (ULULE). I also developed key skills in pitching and presenting to investors and incubators.

📊 I also master modern data and AI tools (ChatGPT... TensorFlow.js...) to create relevant analytical features.

✨ As a communicator and educator, I am committed to sharing my technical and methodological knowledge with rigor and enthusiasm.
