Cybersecurity
Engineer
I'm Pedro Martins, an engineer who builds and operates production systems across AWS, self-hosted, and company infrastructure with security as the architecture, not the afterthought.

Inside My Creative Core
I'm a Cybersecurity Engineer with 3+ years building and operating production systems across AWS, Linux, and containers. My approach starts with the adversarial questions: how does this fail, and what leaks when it does?
I came up through backend automation — securing PII pipelines for enterprises like Hyundai — and discovered the part I couldn't stop thinking about was protecting the systems, not just building them. Today I practice secure-by-default engineering: least privilege, secrets management, hardening, and zero-open-port ingress, on infrastructure I run myself.
