How to Write a Professional Bio
A professional bio is one of the most read things you will ever write — and most people write it once, badly, and never update it. Here is how to get it right.

Step-by-Step Guide
Choose the right length for the context
Long bio (250-300 words): for a full speaker profile, company about page, or author page. Short bio (75-100 words): for a conference program, a guest post byline, or a social media about section. Twitter/LinkedIn headline version (1-2 sentences): for a quick intro in an email or a referral. Write all three — having them ready saves time every time you are asked.
Write in third person for formal contexts, first person for social
Third person ("Jane Smith is a Product Manager...") is appropriate for conference bios, company websites, and published author pages. First person ("I am a Product Manager...") is natural for LinkedIn, personal websites, and speaker introductions where the person introduces themselves. Use the convention that fits the context.
Lead with your current role and most notable credential
The first sentence establishes who you are. Lead with your title, organization, and the most relevant credential or achievement: "Marcus Chen is a Staff Engineer at Google and co-author of the distributed systems textbook used in 40 university programs." Front-load the information that makes them want to keep reading.
Include 1-2 sentences of background and expertise
Add context for your current role: your career arc, your domain expertise, or the specific problem you focus on. "With 12 years in healthtech infrastructure, she specializes in systems that operate at clinical-grade reliability under consumer-scale demand." This signals depth without requiring the reader to parse a full resume.
End with a human detail
One personal sentence makes a bio memorable and approachable: where you are based, a specific interest, or a community contribution. "He lives in Austin with his family and is currently building a community-funded cycling trail in his neighborhood." This is the sentence people actually remember.
