Why You Need a Data Analyst Portfolio

A portfolio for a data analyst serves the same purpose as work examples in other industries. It complements your resume to give prospective employers a deeper look at what you’re capable of when words on a CV may not be enough. That’s important for a few reasons.

First, it helps you stand out in the competition.

The field is growing quickly. The Bureau of Labor Statistics expects data scientist employment to increase by 36% by 2033, leaving plenty of opportunities for hopeful job candidates. But many professionals are aware of this growth, so you’ll face rising competition for these roles.

Second, many data analysis roles can be performed remotely.

Because of this, you won’t just compete against your local labor pool, but you’ll be up against professionals on a potentially national or even global scale. It takes far more than a resume to differentiate yourself, and a portfolio for a data analyst does just that.

Lastly, employers may also specifically request a history or examples of your work.

Companies spent $22 billion on data analytics and infrastructure in 2022 alone and could spend as much as $32 billion on it by next year. Consequently, any analytical errors could be remarkably costly.

Given such high stakes, businesses want to be sure of your skills before entrusting you with their data. A detailed portfolio is your chance to prove they can trust you with the responsibility.

How to Create a Data Analyst Portfolio

Thankfully, building an impactful record of your work and skills is fairly straightforward once you know how to meet employers’ expectations. Here’s how to make a data analyst portfolio in eight steps.

1. Showcase Your Professional Accomplishments

Above all else, your data analysis portfolio should provide examples of analytics projects you’ve completed. While education is still an important part of your resume, 86% of businesses today prefer to hire someone with four years of industry experience over someone with a four-year degree.

Look back over what you’ve done for your current or past positions that show your data analytics skills. Compile a list of the ones you’re most proud of or that seem the most impressive. Be sure to include examples of multiple project types, goals, and datasets if you have them, as this showcases versatility.

For each project in your data analyst portfolio, make sure to include:

A brief summary
The scope and types of data used
Project objectives
Challenges faced and solutions implemented
Final outcomes and impact

Don’t be afraid to describe moments where you’ve had to correct errors or manage unexpected setbacks—these instances show resilience and flexibility.

2. Pursue Your Own Data Analytics Projects

Passion projects and self-sustained work are an easy-to-miss but critical part of your data visualization portfolio. Maybe you're just starting out and lack experience, or your interests go beyond your day job. Pursuing independent projects is a great way to fill these gaps.

Find a data analytics problem, idea, or topic that interests you on a personal level. Then, create your own goals and tackle the project as if it were something you’d do for work. Keep notes of the process so you can list the steps, outcomes, and lessons learned as you would with professional accomplishments.

Pet projects like these serve two purposes in your data analyst portfolio:

They showcase versatility outside of what you’ve done or haven’t been able to do for work.
They demonstrate excitement about data science.

Studies show that passion is positively correlated to commitment to your career, and employers will recognize that.

3. Mention Your Education

A good data analytics portfolio should go beyond just showing your work samples. While project examples are the heart of your portfolio, adding personal details and achievements gives your work more context and meaning. One of the key things to include? Your education background.

Education may not be as crucial as experience in this role, but it’s important to keep in mind that 65% of data analysts have a bachelor’s degree—most employers will value having this credential. Any higher-level degrees will set you apart even more, as just 15% of professionals in this line of work have a master’s.

You should also detail the kinds of analytics work you performed while getting your degree, as this shows how your education is relevant. Consider listing any specific classes you’ve taken that apply to the profession in your data analytics portfolio.

4. List Your Technical Skills and Specialties

In Teneika Askew's portfolio, her certifications take center stage on the first page. She also briefly tells us about herself, which helps create a personal connection.

Remember that a traditional degree is not the only kind of education. Online courses and certifications are also excellent ways to show learning and experience in the work you’ll be performing. These options are becoming increasingly common, with so many online degrees and certification programs available.

Outside of coursework, your data analysis portfolio can showcase any specific skills or specialties you have. General education and experience may look largely the same between data analysts, but people’s unique areas of expertise vary. These are good opportunities to stand out, so cite anything that shows where your talents or knowledge are particularly strong.

You can also list the industries you’ve done the most work in, other jobs you’ve held that help you work with certain topics, or any computing languages you’re proficient in with relevant certificates.

5. Tell People About Yourself

The best data analyst portfolio examples also include a short bio section. Telling clients and employers about yourself is a chance to relate to them on a human level and give them an idea of how you’ll fit within the broader organizational culture.

As many as 90% of today’s employers say it’s important to them to find recruits who are a good cultural fit. But the things that make someone mesh in a workplace don’t always appear in their skills or experience. Being open about yourself in your portfolio is a great way to close this gap and let recruiters recognize your value within their company culture.

A good biography includes a bit about your professional and educational background, how and why you got started in this field, your career goals, and your specific interests or specialties. It should mostly focus on work-related concerns, but feel free to add some personal details in your data analyst portfolio. Showing passion for something can make you stand out as an enthusiastic and engaged employee.

6. Consider Building a Blog

Another way to make your portfolio stand out is to start keeping a blog. As you take on new projects or think of interesting topics in data science, compile your thoughts into regular blog posts. These don’t need to be long or contain anything revolutionary, but they can boost your value as a data analyst in several ways.

The primary advantage of a blog is that it demonstrates your ability to boil complex, data-heavy topics into natural language. Communicating analytics findings is a huge but often overlooked part of the job. While 82% of modern companies use dashboards to communicate findings, 61% say these lack context. By contrast, 92% say storytelling is an effective way to deliver results.

In addition to honing your data storytelling skills, running a blog shows that you’re fully engaged in the field. Employers know these posts are not part of your profession, so the fact that you’ve taken the time to craft them shows you’re dedicated to what you do.

So, when thinking about how to create a data analyst portfolio, don’t forget to think outside of the usual websites—create your own!

7. Include Testimonials

Depending on how long you’ve worked in this field, you may have a few satisfied clients. Reach out to these parties to see if they can provide testimonials about the quality of your work. Co-workers and former employers may be able to offer similar reviews.

People often see reviews as more trustworthy than claims you make yourself. While this is most common in consumer circles, it applies to business contexts, too. Studies have found that 86% of B2B buyers say reviews are important to their decision-making. Even if you’re not necessarily selling something, you should capitalize on that tendency when marketing yourself as an asset.

Testimonials shouldn’t take up too much space in your data analyst portfolio, but you should include a few sentences from previous clients if available. Quotes from educators, colleagues, and readers of your blog can also work if you haven’t been able to complete projects for any professional customers yet.

8. Choose Where to Host Your Portfolio

Tim Hopper’s site provides clear links to his GitHub and social media, and also has a section with links to his other websites.

Once you’ve compiled all these elements, you’re ready to build your data analyst portfolio. But there’s one more step you shouldn’t skip. You’ll need to decide where to host it to make the most impact.

GitHub is a popular choice, as 94 million developers, including 90% of the Fortune 500, use the platform. Still, while GitHub is a great place to share your data science projects, it’s not the best for organization or blogging. Similarly, you can showcase your experience and link to completed projects on LinkedIn, but it may not support all file types.

One alternative is to build a dedicated website for your portfolio. Here, you can host your blog, highlight projects, and cite testimonials, all while linking to your LinkedIn and GitHub pages. You can also include a link to this website on your resume and in your profile on job sites like Indeed.

Data Analysis Portfolio Tips and Best Practices

Now that you know how to create a portfolio for data analyst positions, you should keep a few best practices in mind. Following these three tips will give your site an additional edge when appealing to potential employers.

Keep It Simple

At first, it may be tempting to include every project you’ve ever completed. While that may be the case if you’re just getting started in this career, you’ll eventually have too much to fit in without drowning recruiters in information. Focus on highlighting your best work rather than showing all of it.

To ensure recruiters notice your best efforts and most impressive accomplishments, make those the focal point of your data analyst portfolio.

Be sure to keep a variety of project types on your site, but don’t include too many examples in each category. Rather, aim for just a few of each kind to ensure hiring staff have time to take in all your best work.

Keep It Organized

Similarly, avoid listing everything in a single column. Your portfolio should be well organized for two main reasons. First, it makes it easier for prospective employers to find what’s most relevant to them. Second, it offers an example of your data visualization and communication skills.

Split project examples into different categories. Organize your work, reviews, and links on separate pages, with clear navigation menus at the top to help visitors find each section. Use simple designs and contrasting colors to catch the eye but minimize distractions.

Keep It Up to Date

Remember to update your data analysis portfolio as time goes on. Keep adding to your blog and changing up the projects you highlight even after securing the position you want. Keeping your portfolio updated as your career grows will help attract opportunities you haven't yet imagined and ensure your site accurately reflects your current professional level.

It may seem counterintuitive to update your data analyst portfolio when you’re satisfied with your current role, but you never know when something else will come along that you weren’t expecting. A recent study found that 37.3% of employees are passively open to new positions but not actively looking for one—and employers are aware of this. An up-to-date site helps you stand out among these passive candidates.

As you complete new projects or gain new certifications, remember to replace existing portfolio entries rather than add to them. Think of it as an opportunity to showcase newer and better work, not a larger volume of it.
