In the article you will learn:
What is a portfolio?
First and foremost, it’s important to understand what a portfolio actually is. Nowadays, the term is often used to refer to various websites, LinkedIn profiles, or even CVs—though this isn’t entirely accurate. Put effort into it, as it serves as a calling card for every skilled professional – whether you’re a developer, designer, or creative.
A work, career, or professional portfolio is a tool that helps Java Developers showcase work experience, skills, and accomplishments. Compared to a LinkedIn profile or CV, it is usually more detailed. You can describe individual roles and milestones in greater depth – even in a few sentences or paragraphs.
A portfolio gives you much more space than any other document you might send to clients or employers. It often includes samples and detailed descriptions of your work – such as links to completed websites or applications you’ve built. Another option is incorporating photos or even videos where you discuss a project in more detail.
The difference between a CV, LinkedIn and a portfolio
To better understand what a portfolio is, let’s compare it to a standard CV and LinkedIn profile.
CV
In most cases, a CV is concise and straightforward. It includes a few basic sections, such as personal details, education, work experience, and skills. Information is listed in bullet points or short sentences, with some sections (e.g., education and work history) arranged in reverse chronological order. A programmer CV shouldn’t contain too much information, which is why it’s often supplemented with a cover letter or portfolio.
In many ways, LinkedIn resembles a CV. Details about individual roles or skills are usually more succinct. However, a LinkedIn profile can provide potential employers with more insight into you – especially through published posts or articles. Even so, it’s a good idea to complement it with a portfolio.
Portfolio
A portfolio typically takes the form of a website, online presentation, PDF document, or video. Its design depends on your preferences. Unlike a CV, which should be minimalist, an online portfolio allows you to unleash your creativity. Just ensure the final product is logical and easy to navigate. The information can be more extensive, but avoid overly long paragraphs. Include only the key details – a few of your best projects will suffice – you can always discuss the rest in an interview.
How can creating a portfolio help with job hunting and attracting clients?
Now that you know what a portfolio is, let’s explore how it can assist you in your job search.
A well-crafted portfolio makes a strong first impression and presents you effectively to clients or employers. It also provides additional information that you’d otherwise have to include in a cover letter or follow-up email (such as links to finished apps, websites, or other projects).
Another big advantage of a portfolio is that, unlike a CV, it doesn’t follow a strict template. You can tailor it to your exact needs, helping you stand out from other applicants.
A portfolio also demonstrates your professionalism. A website, online presentation, or PDF document showcases your experience far better than a simple list in an email or cover letter.
What should a portfolio include?
A portfolio should primarily focus on your work experience – this is where you should dedicate the most space and attention. Beyond basic details like job titles, employment periods, and companies, mention your responsibilities, key achievements, and what you learned.
Also include something about yourself – your interests, skills, and education. However, these details are secondary, and since they’re usually covered in your CV (which you’ll send alongside your portfolio), they don’t need to be as extensive.
What projects to include in a Java developer’s portfolio?
If you’re a Java developer and just starting to work on your portfolio, first focus on your projects – from the initial brief to the final implementation. The best ones will demonstrate your technical skill level and whether you’re a suitable candidate for the job. Often, the biggest challenge is selecting the right projects that will impress potential employers.
Your Java portfolio should include:
Real-world projects
If you’ve ever contributed to open-source projects on platforms like GitHub or GitLab, be sure to mention them in your portfolio. This shows that you can understand others’ code and work well in a team.
Personal projects
Do you have a personal project you’ve been working on? Whether it’s applications, frameworks, API services, or anything else, feel free to add them to your portfolio. This signals to potential clients that you’re genuinely passionate about the field and continuously improving your skills in your free time.
Commercial projects
This includes all work you’ve done for employers or clients. Examples might include corporate applications, internal tools, database work, and similar projects.
Portfolio for beginners
Even beginners can create a strong portfolio that presents them in a positive light. If you’re applying for your first job and unsure what to include, here are some suggestions:
- Student or hobby projects – If you’re studying a technical subject like computer science, you’ve likely worked on at least one project that could appeal to a potential employer. Another option is mentioning your bachelor’s or master’s thesis if it involved programming or software solutions. If you’ve switched to Java development later and studied a different field, include your personal coding projects.
- Code challenges – You can showcase your skills through coding challenges – programming tasks or problems you’ve solved. Popular platforms for such challenges include LeetCode, HackerRank, and CodeWars.
How to present your projects?
There are several ways to showcase your completed projects. Each format has its advantages – a brief description is ideal for a quick summary, a code repository demonstrates your technical precision, and a live demo lets employers or clients see the result in action. Combining multiple methods can enhance your portfolio’s credibility.
Brief project description
The simplest way to show employers what you’ve worked on. The description should include the project’s purpose, technologies used, challenges you faced, and the results. You don’t need excessive detail – just the key points. You can elaborate more in the results section.
GitHub repository
A great way to present your code. A well-organised repository with a README file (project documentation) provides essential details about the project, technologies used, etc.
Demo applications
If you’ve built an app and want to show it to potential employers or clients, first choose a hosting platform like Heroku, Render, Netlify, or Vercel. Then, add a link to the live demo in your portfolio.
Technology stack
You can also present your application or any other project by listing all the technologies, programming languages and tools you used to create it, such as Spring Boot, Hibernate, REST API, Docker, and others.
Tests and documentation
These make your portfolio appear more professional. Documentation helps others understand your code, while tests prove its quality and functionality. Mention unit tests, integration tests, or end-to-end testing.
Project presentation via a website
On a website, you can describe your projects in more detail – either as a traditional article or a case study. Case studies are particularly popular as they demonstrate real-world applications of your work.
How to create a professional online presentation?
Building a strong portfolio isn’t difficult, but you’ll first need to decide which format works best for you.
- Personal website – A website looks professional and trustworthy but requires more time and often financial investment. Templates and portfolio samples can simplify the process by handling the web design.
- LinkedIn and GitHub – You can also showcase your projects and work through LinkedIn and GitHub profiles. The advantage is that they’re free, quick to set up, and easy to update.
- Medium/Dev.to blog – If you have more time, you can write a blog about your projects, new skills, and experiences. You can integrate it into your LinkedIn and GitHub profiles or feature it on your website. Popular blogging platforms include Medium and Dev.to.
- YouTube or podcasts – You can use these to showcase your past projects or offer mentoring – another great boost for your career.
- PDF document or presentation – An ideal choice for anyone who doesn’t want to spend hours creating or updating a portfolio. You can easily send a PDF document or presentation to an employer along with your CV.
What do recruiters and hiring managers look for?
During the selection process, recruiters and hiring managers evaluate several factors. In a portfolio, they pay particular attention to code readability, clarity, and structure. They also look for the use of best practices, such as SOLID, DRY, or Clean Code, and the relevance of projects. They assess which technologies you work with and whether they are currently in demand in the market.
For hiring managers, the quality of documentation and written content is also important, as well as your activity in the IT community – whether you follow or participate in conferences and meet-ups, or contribute to open-source projects.
If you’re a freelancer, your portfolio is your primary sales tool. Recruiters and clients look not only at the technical level of your projects but also at their business impact – what specific problems you solved and what results they delivered. How you present your work is also crucial – clear descriptions, real code samples or functional demos, and the way you communicate solutions to clients.
Common mistakes when creating a portfolio
When building a portfolio, you can make several mistakes. One of them is failing to keep it up to date – it should reflect your most recent work. Ideally, update your portfolio every six months.
The most frequent mistakes include:
- Unclear or incomplete GitHub
- Outdated or weak projects
- Lack of real work examples
- Overly broad focus
- Missing explanations and context
- Chaotic appearance or illogical organisation of information
