What should a short professional bio include?

Five things, in this order: who you are, what you do, who you do it for, one proof point, and one human detail. Anything beyond those five is usually the part that should be cut. The proof point is what separates a bio that works from one that reads as filler.

How long should a short bio be?

Match the length to the slot. One line for a byline or profile tagline, around 50 words for a website or speaker page, and around 100 words when you have room for proof and personality. Very few contexts justify more than 150 words.

How do I write a bio about myself in third person without it feeling strange?

Write it in first person first, then convert the pronouns and read it aloud once. Feeling odd about it is normal and does not show in the finished text. The one thing to watch is that third person tempts people into grander claims than they would make as themselves, so keep the same factual restraint.

What do I write if I do not have impressive achievements yet?

Use scope and specificity instead of prestige. What you work on, who you work with, and the size or type of the problem are all concrete without requiring an award. ‘Writes documentation for a 30-person engineering team’ tells a reader far more than ‘passionate about communication’.

Do I need a different bio for every platform?

No. Write one 100-word version, then cut it down to 50 and to a single line. Keep all three in a note and adapt the emphasis rather than starting again. Most people need the short one far more often than they expect.

How to write a short professional bio

Q: Should a bio be in first person or third person?

Match the context. First person for a personal site, a LinkedIn About section, or anywhere you are clearly speaking as yourself. Third person for a conference programme, a company team page, a book jacket, or a byline, where someone else is nominally presenting you. Write one version, then switch the pronouns.

A bio is not your life story. It is a quick answer to one question: why should this person care who you are? Most bios fail by trying to cover a career instead of earning ten seconds of attention. The trick is to be specific and to stop early.

What to include

Five parts, in this order. Almost any bio you will ever need is a longer or shorter version of this.

Who you are. Your name and your role, in the words a normal person would use.
What you do. The actual work, not the job title’s self-description.
Who you do it for. The audience or the kind of organisation. This is the line most people skip, and it does the most work.
One proof point. A number, a named employer, a recognisable client, a shipped thing. One is enough.
One human detail. The line people actually remember.

Write the length the page needs

One line for a byline, a profile tagline, or a conference badge.
About 50 words for a website, a speaker page, or a panel introduction.
About 100 words when you have room to add proof and personality.

Write the 100-word version first, then cut it to 50 and to one line. Cutting down produces a better short bio than padding up, because you keep the strongest material rather than reaching for filler.

Examples by length

One line

Product designer working on software for people who find software difficult.

About 50 words, first person

I am a product designer who helps small teams build software that non-technical people can actually use. I spent six years at a fintech untangling complex flows, and now build practical tools on the side. I live in Edinburgh and make a poor but enthusiastic coffee.

About 100 words, third person

Dave Weatherall is a product designer who helps small teams ship software that older and non-technical users can actually use. He spent six years at a fintech turning complicated account flows into something people could finish without calling support, and now builds and runs a suite of small writing tools used by several thousand people a month. He writes about design decisions that are unglamorous but load-bearing, and is happiest working on the parts of a product nobody wants to own. He lives in Edinburgh and makes a poor but enthusiastic coffee.

Examples by context

LinkedIn About section, first person

Slightly warmer, and it can afford to say what you are looking for. Pairs with your LinkedIn headline, which is doing more of the work than the About section is.

I make complicated software feel simple, usually for teams too small to have a design department. Most of my work is in fintech and B2B tools: onboarding that people finish, forms that do not lose your data, admin screens that a new hire can learn in a morning. Six years at Monzo-adjacent scale, four as a freelancer before that. I am currently taking on one or two projects a quarter, and I am most useful when something works but nobody enjoys using it.

Speaker or conference page, third person

Priya Raman is a staff engineer at Sable, where she leads the team responsible for payments infrastructure processing around £400m a year. She has spent a decade on systems that are not allowed to fail, and speaks mostly about the boring operational work that keeps them running. She has a low opinion of microservices and will explain why if asked.

Company team page, third person

Tom joined as our second support hire and now runs the team. He is the reason our median first-reply time is under an hour, and the person most likely to have already written the help article you are looking for. Before this he taught secondary school maths, which he says was harder.

Byline for an article

Priya Raman is a staff engineer at Sable and writes about payments infrastructure.

First or third person

Match the context rather than your preference. First person for a personal site, a LinkedIn About section, a newsletter, or anywhere you are plainly speaking as yourself. Third person for a conference programme, a company team page, a book jacket, or a byline, where someone else is nominally introducing you.

Write one version and switch the pronouns. The content does not change. The one thing to watch is that third person quietly invites grander claims than you would make in your own voice, because it feels like someone else is making them. Keep the same factual restraint in both.

Weak

Priya is a visionary technology leader and passionate advocate for engineering excellence, with a proven track record of driving transformational outcomes across the payments landscape.

Stronger

Priya is a staff engineer at Sable, where she leads the team behind payments infrastructure that handles around £400m a year.

If you do not have an obvious achievement

Most people writing a bio feel they have nothing to put in the proof slot. The fix is scope and specificity rather than prestige. All of these are concrete and none require an award:

The size or type of the team or organisation you work with.
The particular problem you handle that others avoid.
How long you have been doing it.
A thing you made that exists and can be pointed at.
What people come to you for.

“Writes the documentation for a 30-person engineering team” tells a reader far more than “passionate about clear communication”, and it is available to almost everybody.

Common mistakes

Listing every job. A bio is highlights, not a CV.
No specifics. “Passionate professional” and “results-driven leader” tell the reader nothing and are true of everyone.
No personality. One human line is what people actually remember.
Job-title language. If your mother would not understand the sentence, rewrite it.
Letting it go stale. A bio naming a job you left two years ago is worse than a shorter one that is current.
Writing a fresh one every time. Keep three lengths in a note and adapt.
