Want to grow in your tech career? Start a “brag document” today.

It sounds arrogant, but it’s actually just smart documentation.

I’ve been in tech for over a decade, living and working abroad for the last few years. I’ve noticed a pattern in almost every company: good work does not speak for itself.

If you don’t record your contributions, they get lost or remain invisible.

We often assume our managers remember every bug fix, every optimized query, and every time we helped a junior dev. The reality is, they have their own work to worry about. If you rely on memory for your performance review, you’re leaving your promotion up to chance.

A brag doc is a simple, running record of your wins. You can use Google Docs, Notion, or even Apple Notes. Just write it down! I keep mine updated weekly with:

• Projects delivered (and the specific role I played)
• Measurable impact (did that refactor speed up build times? by how much?)
• Positive feedback (screenshots of Slack messages, emails from stakeholders)
• Ideas that improved team processes
• Knowledge sharing (presentations, docs written, mentoring sessions)

When review cycle comes around, you don’t stare at a blank screen wondering what you did for the last six months. You open your doc, copy-paste your evidence, and make a concrete case for your impact.

It’s your career. Don’t expect anyone else to track it for you.
