The most common reason a strong engineer gets filtered out is not keywords. It is that every bullet on the resume describes a responsibility rather than a result. 'Responsible for the payments service' tells a reader what you were assigned. It says nothing about whether you were any good at it.
A bullet that works names three things: what you did, how you did it, and what changed because of it. The third is the one people leave out, and it is the only one a hiring manager is actually reading for. This rewrites each bullet you paste, keeps your facts, and tells you which number to go and find when a bullet has no outcome to point at.
Questions people ask
What makes a resume bullet point strong?
It names the action, the method, and the measurable outcome. 'Cut p99 latency from 900ms to 120ms by adding PgBouncer and consolidating three queries into one' works because every clause is checkable. 'Responsible for database performance' does not.
Will it invent numbers for me?
No, and that matters more than it sounds. An invented metric falls apart in the first interview where someone asks how you measured it. Where a bullet has no outcome, it tells you exactly which figure to go and find.
How many bullets should I paste at once?
Six or fewer. The rewrite is better when it can see the pattern across a few bullets from the same role, and worse when it is handed an entire resume at once.
Do these bullets get past an applicant tracking system?
An ATS filters on keywords and parseability, not on writing quality. Use the resume checker for that. Strong bullets are for the human who reads you after the filter, which is where most rejections actually happen.
