Thoughts on software architecture, building scalable SaaS products, and optimizing enterprise email infrastructure for high deliverability.
Building is cheap. Attention is expensive. And verifying AI-generated technical debt is the new bottleneck in software development. Here is how to survive and thrive as a system architect.
The exact DNS records, PowerMTA DKIM config, alignment troubleshooting, and validation commands I use to pass authentication on every domain.
The exact commands, accounting-log fields, and threshold numbers I watch daily to spot deferrals, blocks, and reputation drops before they cause blacklisting.
Real explain() output, compound index strategies, aggregation pipeline fixes, and when to bring in Elasticsearch — from optimizing 40M+ records.
My step-by-step production setup — server hardening, PM2 cluster mode, Nginx reverse proxy, Let's Encrypt SSL, and zero-downtime deployments.
The exact day-by-day warmup plan I use for every new IP and domain — with PowerMTA config progression, Google Postmaster Tools monitoring, per-ISP throttling, and more.
My production setup — Virtual MTAs, IP rotation, bounce processing, domain throttling, and MailWizz integration.
