At PlasBit, I own PCI DSS 4.0.1 compliance for a regulated crypto payments platform. I passed certification and reverification with external auditors and deliver evidence across all 12 PCI requirements.
I engineered Wazuh detection across Linux and Windows endpoints and AWS services, tuning log events to critical-only alerts routed into DFIR-IRIS. I also maintain Puppet modules for system hardening and compliance baselines.
I co-built a blue-green deployment system using target groups, Auto Scaling, and load balancer switching, replacing single-server releases and adding traffic-switch rollback. I also migrated production MongoDB from a self-managed EC2 instance to Atlas.
I founded and operate Zalfres, an early-stage SaaS that routes waiter orders to a real-time kitchen screen and serves three paying restaurants. I manage its infrastructure on Google Cloud Run, Cloudflare, and Neon Postgres.
