What I'm looking for

I want to work on secure, high-availability fintech platforms with strong engineering practices—using Java and cloud-native architectures—while helping expand authentication, fraud detection, and practical AI integrations to improve security and operations.

I am a highly enthusiastic Java software developer with hands-on experience gained through personal projects and production work. I have served as a Lead Developer at EGS/Worldline (2018–Present), where I spearheaded management and enhancement of the ACS3 (Access Control Server) platform for secure online transactions using the 3D Secure protocol.

I architect and implement advanced authentication methods to strengthen transaction security, designed and developed a fraud detection engine that significantly reduced fraudulent transactions, and integrated multiple banking systems to ensure interoperability and compliance with PSD2. I also ensure full compliance with PCI-DSS and maintain high availability (99.9% uptime), while leading technical initiatives in a fast-paced, regulated environment; since 2026 I have been a member of an AI squad, analyzing AI integration opportunities for the ACS project.
