What I'm looking for

I'm open to remote and relocation opportunities where I can build and operate secure, highly available cloud infrastructure, automate delivery, improve observability, and optimize costs for production SaaS or regulated workloads.

At T4ISB, I architect a multi-tenant biometrics SaaS platform on AWS, with dedicated tenant compute, PostgreSQL, and secrets that can ship in under four business days. I also built active-passive disaster recovery for banking systems, reducing recovery to an 8-minute RTO and 90-second RPO.

I codified 140 AWS resources with Terraform and built GitHub Actions and Atlantis review gates, reducing environment provisioning from two days to 22 minutes. By right-sizing 60 EC2 instances and designing autoscaling, I cut monthly compute spend by 72% while maintaining P95 latency below 250 ms.

Previously, I automated GitLab CI/CD and Ansible delivery across services at STEPS and Younes Consulting, improved Nginx throughput, and built Prometheus/Grafana monitoring. I bring a master's degree in Cloud Computing and hands-on experience operating secure, observable production infrastructure.
