Security-focused ServiceOps Engineer · Sysadmin & Dev in C/Python · Securing and automating infrastructure with Linux/Proxmox, Docker & CI/CD
I'm a security-oriented systems engineer with a strong background in infrastructure automation, cybersecurity, and backend/system tooling. I specialize in designing and operating secure, reliable service delivery platforms that bridge deep sysadmin expertise with modern software development practices.
My technical work centers on:
- Infrastructure Automation & Operations: Linux/Proxmox, Docker, CI/CD pipelines, automated provisioning and maintenance
- Cybersecurity: Network scanning, vulnerability assessment, hardening, secure architecture and defense strategies
- ServiceOps & Platform Engineering: Multi-tenant environments, VPS/SaaS platforms, observability and reliability
- Polyglot Development: C, Python, Shell, Go, JavaScript (practical, product-focused, not hype-driven)
I contribute actively to open-source projects and lead initiatives at organizations like MadeiraHackerSpace, balancing hands-on coding with architecture and operational decisions.
catnet_scanner · C
A high-performance network scanner built for security professionals. Designed for internal corporate networks, providing granular control over scanning behavior, timing, and output formats.
Tech: C, low-level networking, custom protocol handling
Why it matters: Pure C implementation showcases systems-level thinking, performance tuning and security discipline.
mhc-cloud-panel · Python/Proxmox
Multi-tenant cloud panel for VPS resale and infrastructure management. Built on Proxmox VE, enabling MSPs to manage customer virtual machines, billing, and resource allocation through a unified control plane.
Tech: Python, Proxmox API, PostgreSQL, REST APIs, multi-tenancy patterns
Impact: Powers real infrastructure management for MadeiraHackerSpace's cloud services.
odoo-serviceops · Infra/Odoo/Shell/Python
ServiceOps-focused platform for running Odoo Community as a business-critical application on secure, automated infrastructure. Includes containerization, CI/CD integration and operational tooling for IT service companies.
Tech: Linux, Docker, Shell scripting, Python, PostgreSQL, Odoo Community
Focus: Treating ERP as a mission-critical workload — automating deployment, updates, backup and hardening in a reproducible way.
| Category | Technologies |
|---|---|
| Languages | C, Python, Shell/Bash, Go, JavaScript, Lua |
| Infrastructure | Linux, Proxmox VE, Docker, basic Kubernetes concepts, CI/CD (GitHub Actions, GitLab CI) |
| Automation & IaC | Ansible, scripting for provisioning and maintenance, (Terraform – in learning/adoption) |
| Platforms | Self-hosted apps (e.g. Odoo ERP), PostgreSQL, Redis, Nginx |
| Security | Network scanning, vulnerability assessment, hardening, secure service operations |
| DevOps/ServiceOps | Automated deployments, monitoring & logging, multi-tenant architectures, backup & recovery practices |
I maintain an active presence in open-source ecosystems:
- Arctic Code Vault Contributor – Code preserved in GitHub's Arctic Code Vault
- Pull Shark – Meaningful pull requests across multiple projects
- Organization Lead – Active contributor and maintainer at MadeiraHackerSpace
- Infrastructure automation scripts and DevOps tooling for Linux/Proxmox environments
- Proxmox ecosystem integrations and operational workflows
- Security-focused tooling in C and Python (scanners, helpers, internal tools)
- Multi-tenant and service-oriented patterns for self-hosted platforms
I'm a disciplined lifelong learner. My learning repositories document structured study across:
- Language paradigms (C, Go, Rust, Dart)
- Modern frameworks and tooling
- Security research, scanning and exploitation techniques
- Systems programming and low-level optimization
Each learning project includes clear objectives and practical experiments—documenting real growth, not just content consumption.
I'm always interested in:
- Security & Infrastructure discussions – networks, hardening, threat modeling, secure operations
- Open-source collaboration – especially infrastructure tooling, security tools and DevOps/ServiceOps
- Platform Engineering & ServiceOps – designing systems that scale securely and are operable in the real world
- Mentorship – helping others break into security and systems engineering
