About Yosri

Senior IT Consultant specializing in full-stack engineering and advanced security testing, I support organizations in designing, building, and securing high-performance digital systems in complex and demanding environments.

With a strong track record across sectors such as banking, insurance, and industry, I bring a dual expertise combining robust software development and deep cybersecurity practices. I design scalable architectures, deliver clean and maintainable code, and ensure systems are resilient by design.

My expertise extends to penetration testing, secure code review, and vulnerability assessment, enabling organizations to proactively identify risks and strengthen their security posture. I focus on embedding security early in the development lifecycle through a DevSecOps approach, aligning engineering excellence with risk management.

I am particularly driven by building secure, reliable, and future-proof systems that meet both technical and regulatory requirements, while delivering measurable business value.

    March 2024 - August 2025 (1 year and 5 months)
    Luxembourg, Luxembourg
    Led the design and implementation of a robust interoperability solution to synchronize Microsoft Dynamics NAV with the B2C e-commerce platform Wengler.lu, ensuring seamless data exchange and real-time consistency across systems.

    The project focused on enabling reliable bidirectional synchronization of key business data, including product catalog, pricing, stock levels, customer information, and order flows. I designed and developed integration layers and APIs to ensure secure, scalable, and maintainable communication between the ERP and the online platform.

    A strong emphasis was placed on data integrity, performance, and fault tolerance, with mechanisms for error handling, monitoring, and recovery to guarantee business continuity. Security was also a key component, including validation controls and secure data flows between systems.

    This integration significantly improved operational efficiency, reduced manual interventions, and ensured accurate, up-to-date information across all customer touchpoints, ultimately enhancing the overall user experience and business performance.
