How to Become a Freelance Data Scientist

If you are considering a career as a Data Scientist, you may wonder about freelance opportunities. Is it possible for Data Scientists to work as freelancers? Data is of crucial importance to all organizations, including small businesses, startups, and nonprofits. Some organizations may not have the means to hire a full-time Data Scientist, and therefore will gladly work with a freelance Data Scientist who can provide the insights the organization needs. You can find freelance data science work by building a list of clients through networking or posting your portfolio and services on freelancer websites like Upwork and Fiverr. The following sections further detail how to find work as a freelance Data Scientist.

What is a Data Scientist?

Data Scientists extract meaning from raw data to detect patterns and propose solutions that meet an organization’s needs, especially the needs to compete and grow. A Data Scientist’s responsibilities include finding valuable data from data sources, developing machine learning algorithms, improving data collection procedures, cleansing and validating data integrity to ensure accuracy, and detecting patterns and solutions based on data. Data Scientists build models based on data, create data visualizations that communicate patterns and findings to stakeholders, and automate collection processes. Because data plays a critical role in the success of any organization, Data Scientists can build careers in business, technology, finance, nonprofits, and many other industries. 

Those who wish to become a Data Scientist should develop the analytical, statistical, and programming skills needed to manage and interpret raw data. These skills include understanding statistics, machine learning, and reporting tools. Aspiring Data Scientists also benefit from understanding the programming languages R, SQL, Python, Java, and C++.

What is Data Science Freelancing Like?

When you work as a freelance Data Scientist, you are running your own small business. This means you have the freedom to set your own schedule and routine, but it also means that you face additional challenges, such as finding and retaining clients. Freelance Data Scientists can look for organizations that may have job postings for part-time or freelance Data Scientists. They can network locally and online to find organizations that need their services. They can also post their services to sites such as Upwork and Fiverr where organizations or individuals may be looking for data science services. 

As with any freelance profession, the key to maintaining good client relations is to have reliable and steady communication, deliver your work on time, and to meet or exceed client expectations. 

Is Data Science Freelancing Right for Me?

Freelancing can be both freeing and frustrating. As a freelancer, you set your own schedule. You choose the clients and projects you want to take on. However, unless you are working with other freelancers to handle such tasks, you are also in charge of communicating with clients and handling all other aspects of the business. This means you handle client complaints, the invoicing, marketing your services, juggling projects, and more. And unlike a full-time position with an organization, your income will likely vary weekly and month to month. The unpredictability of such work may not suit those who prefer routine and consistency.

Steps to Become a Freelance Data Scientist

If you are interested in starting a career as a Data Scientist, you will want to outline the steps needed to meet your goal. This includes outlining your career goals, identifying the right learning method, dedicating time to learning the necessary skills, creating a professional portfolio, networking with others in your field of interest, and starting your job search. 

Determine Your Goals and Learning Path

The first step toward starting a career as a Data Scientist is to identify your career goals and learning path. Is there a particular area of data science you wish to specialize in? What skills do you need to become a Data Scientist? Data Scientists must understand how to use data management and visualization tools, how to use machine learning to process data and forecast outcomes, and how to use R programming, Python, Java, and sometimes other programming languages such as C++. Identifying the skills necessary to reach your career goal will help you determine what learning method to pursue.

How do you go about learning data science skills? While earning a four-year degree related to data science is an option, it is a costly and time-consuming one. Most working professionals wishing to launch a new career as a Data Scientist learn data science skills through on-demand classes, in-person classes, or live online classes. On-demand classes such as those found on Skillshare and LinkedIn Learning provide the most flexibility since you can stop and start the course whenever you choose. The major drawback to the on-demand/self-paced learning method is the lack of access to an instructor if you have questions. In-person classes are those taught by an expert instructor in a physical learning location, allowing you to network with local professionals such as your classmates.

In-person learning works well for those who prefer face-to-face, and it provides access to all necessary equipment and software. In-person classes also incorporate hands-on assignments that help you retain what you learn, develop your skills, collaborate with others, and build a professional portfolio. The major drawback to in-person classes is the extra time and expense that commuting to the class requires. 

Live online learning offers many of the same benefits as in-person learning including real-time feedback from your instructor, the ability to collaborate with classmates, and the use of hands-on assignments. Live online classes have the benefit of letting you learn from anywhere. Virtual classes do, however, require that you have the necessary software and tools needed for you to learn. Remote learning may also mean that your classmates do not live in your local area, so the class may not provide the chance to network locally.

When deciding which learning method works best for you, keep both your budget and learning preferences in mind. If you want to start learning data science skills before committing to a paid learning method, you can explore free learning tools through Noble Desktop’s Data Science Learn Hub.

Learn Data Science Skills

Once you have decided on the learning path that fits your needs, it’s time to start learning the data science skills needed to launch your career as a Data Scientist. Learning these skills requires setting aside dedicated time. If you are taking an in-person or live online class, you will meet a scheduled time, but you may also wish to supplement what you learn in class to help you retain the information and further develop your skills. The skills required to become a Data Scientist include learning programming languages such as SQL, R, and Python, understanding mathematics including linear algebra, calculus, statistics, and probability, and understanding machine learning, natural language processing, and file management.

A critical part of developing data science skills is gaining hands-on experience. In-person and live online classes often include hands-on activities as part of the curriculum. To truly understand the work of a Data Scientist, you must put lessons into practice through hands-on assignments. Such projects also allow you to build a professional portfolio. 

Create a Professional Portfolio

Creating a professional portfolio allows you to show prospective employers the evidence of your hard work and data science skills. Portfolios can also help you to land part-time and freelance jobs as a Data Scientist if you decide to pursue that path or wish to gain additional experience before finding a full-time role. So how does one assemble a professional portfolio for Data Scientist jobs?

If you participate in hands-on activities through an in-person or live online class, you can save your work as part of your portfolio. You can also add other projects that showcase your work if you choose. Having a mentor review your portfolio will help to ensure you have everything you need to make a good impression during your job search. Live online classes and in-person classes that include portfolio reviews and mentorship with your tuition can therefore help you have the edge over the competition when you start your job search.

Make Industry Connections

Making industry connections can greatly benefit you when you start your job search, but networking doesn’t just serve your short-term goals. The industry connections you make can prove helpful throughout your entire career. You can learn new skills from mentors and others in the industry. You may learn about new opportunities through your connections as you work to advance your career. 

In-person data science classes allow you to network with locals while learning the necessary skills to become a Data Scientist. You also have a professional connection through your instructor/mentor. Live online classes also connect you to industry professionals, though not always in your local area. If you want to network beyond your class, identifying local data-related professional organizations can provide a means of connecting with others.

Review Your Resume and Start Your Job Search

The final step to finding a job as a Data Scientist is to review your resume and start your job search. Reviewing your resume with your mentor or another professional helps you to ensure your resume stands out to recruiters. You will want to highlight the skills key to the job you want, including any soft skills relevant to the position. Also, take advantage of any other job search assistance in your data science program.

Once you have a polished resume, you are ready to start your job search. You can find Data Scientist job postings on Glassdoor, LinkedIn, Indeed, and more. Setting up email alerts for relevant keywords and postings can help you stay on top of all available opportunities.

Learn Business Skills

In addition to all the skills of a regular Data Scientist, future freelance Data Scientists will need to learn skills for running their own business (such as finance and contract law) and marketing their business (such as web design and social media marketing). Even freelance Data Scientists who plan to contract consultants to help run their small business should have a basic understanding of these areas to understand what kind of outsourcing they need to support their freelance work.
