I am Ailton Baúque (vybraan), a software engineer with a focus on cybersecurity, web development, and practical systems work. I also serve as a part-time system administrator, where I provision and manage servers, automate deployments, and keep infrastructure secure and reliable.
I am a lifelong learner, currently exploring software testing and embracing the collaborative spirit of DevOps culture. Outside of work, I enjoy a good book, long walks around Maputo City, and the occasional run.
Most of what I build is in Go — CLI tools, auth middleware, and the occasional protocol experiment. Infrastructure, security, OAuth2, and Linux are my daily drivers.
Systems
I run and maintain Linux/UNIX servers, network services, and secure access paths for real workloads.
- Linux, Ubuntu, Debian, Red Hat (CentOS), UNIX, FreeBSD, Solaris
- SSH, TLS, DNS, HTTP, SMTP, IMAP, POP3, LDAP, Samba, SFTP
- Nginx, Apache, Traefik, Redis, PostgreSQL
DevOps
I automate deployments, work with containers, and keep small systems observable and recoverable.
- Kubernetes (k3s), Docker, LXC, VMWare, VirtualBox
- Git, GitHub, GitLab, Gitea, AWS, Vim/Vi, TMUX
Backend
I build practical tools and services, mostly in Go, with security and operations in mind.
- Java, C#, Python, Go, Bash, POSIX Shell, JavaScript, SQL
