Aspiring DevOps engineer building secure infrastructure, including a PKI-secured web app with automated certificate management.
PortugalWhat I'm looking for
I designed and deployed a two-tier PKI for a secure web app, using OpenSSL and mutual TLS on Nginx. I automated certificate issuance, renewal, revocation, and reissuance with Bash scripts.
On that project, I diagnosed a revocation issue that blocked every client and fixed it with a combined Root and Intermediate CRL. I validated access scenarios with curl, OpenSSL, and a browser, and kept CA passphrases out of the code.
For a distributed systems project at UTAD, I built a client-server task dispatch system in C# with gRPC and RabbitMQ. I also set up local SQL Server and RabbitMQ infrastructure with Docker Compose and automated database setup with EF Core migrations.
I'm currently co-developing a mobile platform for event management and social networking, focusing on its C# backend. I'm seeking a DevOps Engineer or Platform Engineer role, and I'm deepening my skills in Kubernetes and platform engineering.
