- Desktop apps: JavaFX, Python
- Cybersecurity: secure coding practices, OWASP-aware development, vulnerability scanning (Snyk), secrets management
- DevOps basics: Docker, Docker Compose, Linux, Nginx, CI/CD with GitHub Actions
- Self-hosted infrastructure: I run my own production-grade VPS with 16+ services, a full SOC stack (Wazuh, Falco, CrowdSec, Prometheus/Grafana), and a centralized secrets vault (OpenBao)
