Email Infrastructure
I am a Site Reliability Engineer focused on the intersection of Python automation and complex email infrastructure. My recent projects involve architecting self-hosted SMTP relays that bypass traditional deliverability hurdles through strict DKIM/DMARC enforcement and custom IP warming scripts. I specialize in troubleshooting edge-case failures in high-traffic LEMP environments. By documenting these real-world case studies, I provide actionable insights into maintaining high-reputation mail servers and optimizing backend script execution for maximum efficiency.
