About

Each topic works through a stack — Python, Django, PostgreSQL, MongoDB, AWS and more — from beginner explanations up to the kind of detail that shows up in a production incident or a senior interview. Every concept pairs a worked explanation with runnable code, and most topics carry a diagram gallery and a printable quick-reference sheet.

Reading requires no account and no email. Your theme and text size are kept in your own browser and never leave it. Pages do carry ads — see the privacy policy for what that means for cookies.

/jobs is an optional, signed-in workspace for the other half of learning a stack: getting hired with it. It aggregates public job postings, ranks them against a résumé profile you provide, and drafts tailored application material with AI models — reviewed by you before anything is saved or sent.

• a résumé profile you control, editable and deletable at any time;
• job triage, notes and saved searches against postings from public sources;
• optional Google Drive export, scoped to documents the app itself creates.

Developers learning a stack for the first time, engineers going deep on a topic they already use day to day, and anyone prepping for an interview or a job search in either case. The two halves share content on purpose — the same explanations that teach a concept are what a technical interview actually asks about.

Pressentify is an independently operated project, offered as-is — see the terms of service for what that means in practice. There is no company behind the domain and no outside funding; it stays free to read because the cheatsheets carry no accounts to bill.
