Secure Multi-Account AWS Landing Zone for Banking

Designed and implemented a production-grade AWS Landing Zone for French banking institutions subject to DORA and RGPD regulations. The architecture provisions seven dedicated accounts across four OUs, with centralized security monitoring, immutable audit logging (365-day S3 Object Lock), hub-and-spoke networking via Transit Gateway with route table segmentation, dual-path hybrid connectivity (Direct Connect + VPN), and cross-region disaster recovery (RTO 4h, RPO 1h).

AWS Cloud Resume Challenge

Architected and deployed a full-stack serverless resume website using S3 (static hosting), CloudFront (CDN), Route 53 (DNS), DynamoDB (visitor counter), and Lambda (API backend) — demonstrating end-to-end AWS architecture design and implementation.

WordPress High-Availability Deployment

Designed and deployed a highly available WordPress application on AWS using EC2, RDS (Multi-AZ), Route 53, Application Load Balancer, and Auto Scaling Groups — showcasing multi-tier architecture, fault tolerance, and scalability patterns.
