Technical Notes Small fixes, practical systems and documented experiments.
This archive collects practical notes from my own technical workbench: Shopify adjustments, Microsoft 365 mail-flow problems, DNS records, automation ideas and other small systems that solved real problems.
These pages are not meant to be oversized tutorials or polished agency case studies. They are working notes: enough context to understand the problem, the idea and the result — without pretending that every solution should be copied blindly.

A growing collection of practical notes about Shopify, Microsoft 365, DNS, automation, e-mail delivery and small technical decisions that solved real-world problems.

Some notes deliberately describe the problem and the direction of the solution without publishing every technical detail. A copied configuration is not always a good configuration.
Built from small business reality, technical curiosity and the occasional desire to make systems behave.
