writing
Files beat a database, and the biggest mistake is blocking the crawlers that actually send you traffic. The whole setup, including what we built for this site.
Almost always missing DNS records, not your code. What SPF, DKIM, and DMARC do, the order to set them up, and the From-address mistake that undoes all three.
mobile
Wrap it in a native shell that loads your existing screens. What it costs, what the stores require, and the in-app purchase rule that decides your economics.
security
Twelve checks that separate a demo from something you can put in front of strangers, ordered by how much damage each one prevents.
jobs
No. A queue on your existing database removes a service to run, secure, and pay for. The real tradeoff, and four rules that make jobs reliable.
payments
The checkout is the easy half. The whole flow, why the webhook is the source of truth, and four failures that let people use what they never paid for.
sign-in
Emailed codes and social sign-in remove the password database and the reset flow. What you gain, what you take on, and the detail everyone gets wrong.
deploy
One command, a $5 box, and a container. What running your own server involves in 2026, what it costs, and when a managed platform is the better answer.
