I'm an aspiring Linux / Systems Administration / Cybersecurity professional based in Sweden 🇸🇪.
I enjoy working close to the system layer: Linux, networking, Docker, infrastructure automation, backend APIs, and the security details that keep things from catching fire.
This GitHub is where I document my hands-on projects, labs, and experiments as I build my way deeper into systems administration and cybersecurity.
Linux administration • Networking • Secure backend APIs • Docker • Infrastructure automation • Cybersecurity labs
A production-style FastAPI backend for secure multi-tenant webhook ingestion, event tracking, message logging, operational metrics, PostgreSQL/Alembic persistence, Redis support, and Docker-based deployment.
Core focus:
- Secure FastAPI backend architecture
- Multi-tenant API design and webhook security
- PostgreSQL, Redis, Prometheus, Docker, and Alembic
Automated server deployment project using Terraform, Docker, Cloudflare, DigitalOcean, Bash, and Linux.
This project focuses on infrastructure automation, server provisioning, DNS configuration, Dockerized deployment, and production-oriented setup practices.
Core focus:
- Infrastructure as Code with Terraform
- Linux server automation and Docker deployment
- Cloudflare DNS and DigitalOcean infrastructure
A backend security learning project built with FastAPI, PostgreSQL, SQLAlchemy, Pydantic, JWT, OAuth2 concepts, and Docker.
The goal of this project is to explore secure authentication, admin-controlled user creation, API structure, and backend security best practices.
Core focus:
- Secure API authentication and authorization
- JWT-based login flows and admin-controlled user creation
- PostgreSQL, SQLAlchemy, Pydantic, and Docker
A Python-based reconnaissance CLI tool for authorized security assessments, lab environments, and security learning.
ActiveRecon combines Nmap scan profiles, DNS analysis, HTTP service detection, header collection, TLS checks, JSON/Markdown reporting, and interesting signal generation into a structured workflow for documenting early-stage reconnaissance.
The project focuses on practical Linux-based security tooling, service enumeration, automation, reporting, and responsible recon methodology.
Highlights:
- CLI-based reconnaissance workflow
- Configurable Nmap scan profiles
- DNS, HTTP, and TLS analysis
- Markdown and JSON report generation
- Scope-aware scanning support
- Interesting signals for follow-up review
- Modular Python project structure
A practical networking lab simulating a multi-site company environment with Stockholm and Helsinki sites, segmented networks, pfSense firewalls, routing, NAT, Active Directory, DNS, DHCP, NTP, GPOs, and Windows/Linux machines.
Core focus:
- Multi-site network design and segmentation
- pfSense routing, NAT, and firewall configuration
- Windows Server, Active Directory, DNS, DHCP, NTP, and GPOs
