I’m a Computer Scientist & Engineer and an independent consultant specializing in OpenBSD and FreeBSD systems.
My work focuses on DevOps, DevSecOps, and secure infrastructure design, with an emphasis on building robust, privacy-respecting, and maintainable systems.
I provide architecture, deployment, and ongoing operational support for high-security Internet and network services, including:
- Hardened and standards-compliant email infrastructures (OpenSMTPD, Postfix, DNSSEC/DANE, spam/abuse mitigation, TLS enforcement)
- Secure, high-availability web hosting environments (httpd/nginx, reverse proxies, TLS automation, load balancing)
- Performance-optimized database servers (PostgreSQL/MySQL tuning, ZFS optimization, backup and replication strategies)
- Network-level security engineering (pf firewalling, VPN design, intrusion reduction, log and audit pipelines)
I also offer remote consulting for system audits, security hardening, infrastructure modernization, and long-term server maintenance on BSD-based or mixed-UNIX environments.
Beyond consulting, I write technical articles and deep-dive gu-ides on my blog: https://ozgurkazancci.com
