What 60+ Hiring Managers Actually Look For in Developer Portfolios

TL;DR: Your portfolio complements your resume—it doesn’t replace it. 65% of hiring managers review portfolios for candidates without experience, but 51% say not having one won’t hurt you. Structure: Hero → Projects (2-5 max) → About → Skills → Contact. Each project needs a case study explaining the problem solved, your role, and results. Avoid: skill percentage bars, unmodified tutorial projects, broken links, poor accessibility. Quality over quantity—hiring managers spend ~3 minutes per portfolio.

Before investing time building a portfolio, let’s address the elephant in the room: do you even need one?

According to a survey of 60+ hiring managers by Profy.dev, 65% would definitely review a candidate’s portfolio if they lack experience, and 93% would probably look at it. However, here’s the twist: 51% indicated that not having a portfolio wouldn’t hurt your chances compared to someone who has one.

Your resume or your LinkedIn profile is the first thing I’ll see. If you apply for a job, I’ll see a resume, I’ll check your work experience and whether what you did in your past jobs matches what I need. If it’s ok then I’ll check portfolio, GitHub profile etc. — Engineering Manager interviewed by Profy.dev

The takeaway? Your portfolio complements your resume—it doesn’t replace it.

The 2025 Reality Check

The landscape has shifted. As Medium’s Dev Tips puts it:

Portfolios went from ‘must-have’ to ‘maybe-they’ll-look-if-they’re-bored.’ Meanwhile, resumes, GitHub, and LinkedIn became the first (and often only) filters.

The Optimal Portfolio Structure

Based on WebPortfolios.dev research, your portfolio should follow this logical flow:

Hero Section (Introduction)
Projects (The most important section)
About Me
Skills
Contact

Hero Section: You Have Seconds

According to Elegant Themes, the hero section is a strategic element designed to guide users, tell a story, and encourage action. This section should make a strong first impression that encourages visitors to explore further.

Users decide in seconds whether to stay on your site. Your hero needs to immediately communicate:

Your name
Your specialty
A clear value proposition

Projects: The Heart of Everything

Almost all traffic to your web developer portfolio will be looking for your projects section—as a developer, it’s what demonstrates your skills in action. — WebPortfolios.dev

How many projects? Josh Comeau, respected developer and educator, recommends:

It’s recommended to showcase between 2 and 5 projects. A portfolio site isn’t supposed to be an index of everything you’ve ever created—it should be a highlight reel.

Lyrid.io backs this up: hiring managers spend approximately 3 minutes per portfolio. Too many projects make it harder to find your best work.

Project ordering matters. Lead with projects that best represent your current skills, not your oldest work.

Skills Section

According to Roadmap.sh, technical skills:

Should be smartly grouped by category—‘backend,’ ‘frontend,’ ‘cloud,’ and more—following industry best practices. Everything should be carefully arranged above the fold for immediate access.

Contact Information

DEV.to emphasizes making contact easy:

Display email and social links in both header and footer; consider fixing contact icons while users scroll.

The Art of Project Case Studies

A weak project description:

Chat app built with React and Socket.io

A compelling one:

Built a real-time chat application for remote teams, reducing message latency to <100ms using Socket.io. The main challenge was implementing automatic reconnection on connection loss, solved through a heartbeat system and offline message queue.

What Every Project Should Include

According to Tobias van Schneider and Semplice:

Project name and context
The problem you solved
Your specific role
The solution process
Technologies used
Results and learnings
Links to demo and source code

Critical insight from Tobias van Schneider (ex-Spotify designer):

People scan, they don’t read. If we scroll through and only read your 1-2 sentence captions, we should still understand the project. The whole thing should take three minutes to read, tops.

Semplice adds:

Make your case study scannable with headlines, short paragraphs and captions.

Critical Mistakes to Avoid

Skill Percentage Bars

This is unanimously criticized across all sources reviewed.

Using percentages to display skills in various technologies does not add any value. No one knows what it actually means. — DEV.to

FreeCodeCamp agrees:

Avoid self-assigned percentages (85% in Angular). Instead, clearly state what you master, what you’re learning, and what you don’t know.

The fix: Use years of experience or number of projects instead—metrics that are universally understood.

Tutorial Projects

For a junior developer to showcase templated projects shows a lack of skill. Anyone can build a Spotify replica, chess game, or random number generator, but not many can apply the teachings from all three tutorials and create something truly unique. — Lyrid.io

The recommendation is clear:

It is best to take the concepts you learned and take them to the next level by adding your own functionality.

Buggy or Incomplete Projects

Sending out an unfinished or buggy project to a hiring manager demonstrates a lack of skill, no care for attention to detail, and creates an unenjoyable experience. Having buggy or unfinished projects in your portfolio says novels about your work ethic! — Lyrid.io

Accessibility Failures

FreeCodeCamp’s review of 50 portfolios found:

34% couldn’t be navigated with keyboard alone
40% had low contrast text/background combinations

Low contrast makes sites unusable for those with low vision conditions.

Over-Reliance on Frameworks

About 19% of portfolios featured projects relying too heavily on frameworks without demonstrating vanilla CSS, JavaScript, or HTML skills.

Bootstrap themes help rapidly build nice looking pages through pre-packaged components. But they conceal pure CSS mastery that companies still require. — FreeCodeCamp

Broken Links

Nothing kills excitement faster than clicking a demo link and getting a 404 error. Test everything, then test it again. Check all your links monthly. — DEV.to

Using Stock Images

BrainStation warns:

Using stock images might be tempting, but custom-designed artwork and unique photography is far more eye-catching. People tend to glaze over stock images because we see them repeatedly. Making it more personable will go above and beyond everyone else.

What Recruiters Actually Prioritize

According to CodersRank and Nucamp research:

60%+ of recruiters look for projects solving real-world problems
70% want to see project variety demonstrating adaptability
Clean, documented code is highly valued
Evidence of continuous learning
Open source contributions

Code Visibility Matters

Without any opportunity to inspect your code, you’re making the reviewer’s job tougher. We’ll struggle to know whether it’s worth our time to move you on to the next step. — FreeCodeCamp

Codementor adds:

By including code samples, recruiters can get a better sense of your coding style, problem-solving abilities, and attention to detail.

Always provide both live demos AND source code access.

Beyond the Code

CodersRank observes:

It’s not enough to have a presence on social media and developer forums - you have to be engaged. Recruiters will look at the conversations you participate in and topics you lend expertise to. It’ll give recruiters insight into your communication skills and technical ability.

Design Principles

Keep It Simple

SiteGround Academy recommends:

The portfolio should have a clean, modern, and professional design that captures your brand with consistent elements across all pages.

For colors, DEV.to suggests:

Opt for simplicity (max 3 colors, 2 fonts) if inexperienced with design, then add creativity as you gain expertise.

Another DEV.to guide adds:

Keep colors minimal — use 2 primary shades + 1 accent color.

Mobile First

63% of global web traffic comes from mobile devices. Your portfolio must work flawlessly on all screen sizes.

Performance and SEO

Run Google Lighthouse before deploying. As DEV.to notes:

Add a custom domain (yourname.dev or yourname.tech). It boosts credibility instantly.

Portfolios Worth Studying

According to Emma Bostian’s GitHub repository and Hostinger’s analysis:

Brittany Chiang — “Her portfolio is a favorite among aspiring developers, featuring a sleek, dark theme with a vibrant accent color, clean layout and crisp typography.”

Bruno Simon — “His portfolio is a masterclass in interactive web design, featuring a game-like experience where you drive a small jeep through a 3D world to explore his projects and skills.”

Tamal Sen — “Nails the developer aesthetic with a sleek dark theme that mimics an IDE, adding code snippets in the background and smartly uses screenshots to showcase his previous projects.”

Jesse Zhou — “Created a 3D portfolio using Three.js and Blender with an interactive experience to showcase his skills, experiences, and hobbies, performing well on both desktop and mobile devices.”

Community Perspectives

From Hacker News

In Hacker News discussions, an important perspective emerges:

Build your portfolio for yourself, not for what you think recruiters/employers want to see. The goal should be to have a place to collect projects you work on, and more importantly, one that captures your personality.

On what hiring managers value, from another HN thread:

Portfolios are often viewed as most relevant for junior devs and graduate students leaving academia. Hiring managers tend to look for things uncommon in those environments: engineering over theory, documentation and tests over novelty.

The Time Investment Debate

The community debates whether portfolios are worth the effort:

It’s debated whether a portfolio matters enough to bother creating one, but a common ground is that it shouldn’t be a task you spend significant time on unless you’re freelancing.

Pre-Launch Checklist

Before publishing, verify:

Key Takeaways

Resume comes first. The portfolio complements, not replaces, a solid CV.
Quality over quantity. 2-5 well-documented projects beat 20 mediocre ones.
Show, don’t tell. Working demos and visible code are essential.
Fundamentals matter. Demonstrate vanilla technology mastery, not just frameworks.
Accessibility isn’t optional. A third of portfolios fail basic navigation tests.
Personality with professionalism. Your portfolio should reflect who you are while maintaining professional standards.

Build something that represents you—and make sure it works.
