Présentation
I build products that combine development velocity with operational excellence.
As a versatile product engineer, I bridge two worlds: the fast delivery of robust backend architectures and the high standards of a fluid and intuitive mobile user experience.
From designing scalable infrastructures to integrating native features, I deploy industrial systems built to last, without ever sacrificing ethics or accessibility: these values are non-negotiable standards for me.
Expertise & Impact
Mobile Ecosystem
Cross-platform development, native integrations, and mobile performance.
SaaS Architecture
Multi-tenant systems, robust APIs, and scalable infrastructures.
Design Engineering
Design Systems, headless components, and accessible interfaces.
Engineering Culture
Automation, end-to-end testing, and DevXP improvement.
Radical Accessibility
Accessibility is not an option, it's a right. Every line of code is designed to guarantee a barrier-free experience, certified by my Opquast expertise.
Privacy First
Ethics is at the heart of engineering. I deploy cookie-less and GDPR-compliant solutions to protect user data integrity.
Industrial Quality
I advocate for tested, documented, and maintainable code. Industrialization (Monorepo, CI/CD) ensures the longevity and scalability of complex products.
Augmented Engineering
AI increases my velocity without ever replacing my judgment. I use these tools to automate tedious tasks and focus on product value.
Engineering Highlights
Native & Web Convergence
Designing cross-platform architectures with Ionic 8 and Capacitor. Advanced management of native APIs: complex hardware permissions, health integrations (HealthKit / Health Connect), and offline storage strategies for critical environments.
Velocity & Complex Systems
Accelerating Time-to-Market via Laravel and Filament. Implementation of robust multi-tenant structures, hybrid monetization funnels (Stripe/IAP), and high-performance administrative dashboards, all in strict compliance with GDPR.
Sustainable Front-end Ecosystems
Managing Monorepos (pnpm) and creating headless Design Systems ensuring large-scale accessibility (Opquast standards). Quality automation via Playwright (E2E) and Vitest, optimizing delivery reliability.
