About Me

I support tech, fintech, and e-commerce companies in designing, building, and modernizing reliable mobile applications that are built to last.

Across high-scale and high-constraint products (logistics, payments, digital identity, mobility, banking), I help teams deliver robust Android/iOS apps, secure critical user journeys, and structure maintainable mobile + backend architectures.

What I Bring

  • End-to-end ownership: mobile, backend (BFF), architecture, CI/CD.
  • Strong expertise in security-sensitive systems and compliance constraints.
  • Ability to frame products technically from MVP stage to large-scale platforms.
  • Pragmatic delivery mindset focused on production outcomes.

Core technologies I use regularly:

  • Flutter
  • Android
  • iOS
  • Kotlin
  • Python
  • Swift
  • KMP
  • Node.js
  • Ktor
  • OpenAPI
  • EUDI
  • OpenID4VCI
  • OpenID4VP
  • Verifiable Credentials
  • TypeScript
  • Docker
  • CI/CD
  • Clean Architecture

Professional Experience

Senior Mobile Engineer @ INGroupe

Apr 2025 - Present

Paris, France

  • Developing a cross-platform digital identity wallet aligned with EUDI wallet reference architecture on Android (Kotlin, Jetpack Compose) and iOS (Swift, SwiftUI).
  • Bootstrapped the application from scratch with modular Clean Architecture, MVI patterns, and secure identity handling flows.
  • Designed and implemented identity SDK capabilities for credential provisioning via NFC (ISO-DEP) and QR code, plus identity derivation/authentication with X.509, PKCS#12, and HOTP.
  • Designed and developed backend issuer services for credential issuance using OpenID4VCI, with secure, standards-aligned API contracts.
  • Implemented EUDI-compatible credential protocols, including OIDC4VCI/OpenID4VCI (issuance), OIDC4VP/OpenID4VP (presentation), and SD-JWT selective disclosure/signature validation.
  • Developed and evolved BFF services to simplify mobile integration, orchestrate identity/payment flows, and reduce client-side complexity.
  • Delivered age-verification and digital badging use cases, including Badgemeup, an EUDI-compliant badging and credential issuance app.
  • Built and maintained mobile CI/CD pipelines with Bitbucket, Jenkins, Fastlane, Docker, and automated quality gates (JUnit, XCTest, MockK).
  • Delivered end-to-end identity-sharing workflows aligned with eIDAS 2.0 requirements while collaborating on architecture decisions, cross-team coordination, and technical mentoring.
