As an app developer, you have the potential to earn between $20 and $40 per hour—a range influenced by factors like your experience, the complexity of projects, and the unique value you provide to your clients.

2. E-commerce website development

Venturing into e-commerce website development will have you creating and enhancing online stores for retailers and entrepreneurs.

Your tasks span from developing engaging storefronts with a responsive design to integrating secure payment gateways and optimizing user experiences.

The earnings potential within the e-commerce development field can vary based on factors such as skill level, experience, and project scope.

On average, a Shopify developer or a WooCommerce developer typically earns an hourly rate ranging from $15 to $29. Similarly, for those who possess more general coding or web design skills, the hourly earnings tend to fall within the range of $15 to $30.

Platforms like Upwork offer an easy way to connect with clients looking for e-commerce expertise. Simply showcase your e-commerce portfolio—which might include online storefronts and product displays—and reach out to potential clients to secure your first project.

3. Online coding courses

Creating online courses lets you share your programming expertise with eager learners on platforms like Udemy. You can create in-depth lessons on areas like web development, coding languages, app creation, or AI. The courses can even include hands-on exercises or fun projects for your students to work on.

You also don’t need professional filmmaking skills. You can simply videotape yourself explaining concepts, add a voiceover to your screen recordings, and even use user-friendly programs to create stunning visuals that make learning easy.

Pricing for these courses can vary widely. Some courses may be priced as modestly as $20, while others can command higher prices. Your earnings as a course creator are closely tied to two key factors: the level of engagement your courses achieve and the number of students who decide to enroll and make a purchase.

4. Affiliate marketing for tech products

Engaging in affiliate marketing for tech products offers a unique way to promote cutting-edge software and tech items while earning commissions. This side job involves partnering with software and tech product companies that align with your passion for technology. Your role is to market these products to your audience through various platforms like websites, blogs, social media, and more.

By embedding special affiliate links in your content, you can track the sales generated through your promotions. You earn commissions based on a percentage of sales made through your links.

Specific earnings from affiliate marketing can fluctuate significantly, as they are typically a percentage of the total sales. This percentage often falls within the range of 5% to 30% of the total product cost.

What sets affiliate marketing apart from traditional business models is that it doesn't demand you to manufacture the products or handle customer service; instead, you focus on marketing strategies and delivering value to potential customers.

5. Plugin and template development

Template and plugin development involves creating tailored components for platforms like WordPress and Shopify. These elements serve as essential building blocks to enhance website functionality, aesthetics, and user experience.

Plugins enable seamless integration of specialized features, ranging from e-commerce capabilities to SEO functionalities. On the other hand, themes and templates provide visually appealing designs coupled with user-friendly interfaces.

Once you've made these plugins and themes, you can set up your own online store to sell them. But remember, you'll need to let people know about your products. That's where platforms like Upwork come in handy.

Upwork connects you with clients who are already on the lookout for plugins and themes for their businesses. It's an easy way to find people who need what you're offering without the hassle of searching around.

On average, a web designer might charge between $15 and $30 per hour for their services. However, specializing in certain aspects of web design, along with your personal experience and skill set, can open the door to higher-paying clients.

6. API and SaaS solutions

If you've got a knack for business and a passion for problem-solving, getting into API development and Software as a Service (SaaS) solutions might be for you.

Tasks involve understanding the unique challenges of a business, designing APIs that facilitate smooth data exchange between different software systems, or crafting SaaS platforms that offer efficient solutions.

Platforms like Upwork can connect you with clients seeking your tech expertise. With an average hourly rate of $15-$30 for software developers, your earnings can grow with the experience and complexity of projects.

7. YouTube coding tutorials

Creating YouTube coding tutorials lets you share your knowledge as a programmer with a global online audience. By creating engaging and informative videos, you have the chance to empower aspiring coders and tech enthusiasts while building a community around your channel.

To make the most of this side hustle, focus on creating content that's accessible to learners of various skill levels. Walkthroughs, problem-solving sessions, and coding challenges can really capture your audience.

However, you should be realistic about monetization. While YouTube does offer potential earnings through ad revenue and memberships, building a substantial income takes time, consistent effort, and a sizable viewer base.

To monetize your YouTube channel, consider joining the YouTube Partner Program to access ad revenue and channel memberships. Additionally, you can explore sponsorships, merchandise sales, and even offer premium content through platforms like Patreon. You’ll need to balance your passion for teaching with a practical understanding of the income potential.

8. Freelance software development

If you want to manage your own schedule and share your coding expertise with businesses across the globe, software development freelancing is a great option to showcase your tech skills. Upwork’s platform provides you with the opportunity to find coding jobs, whether you're a versatile full-stack developer or a specialized back-end expert.

If you choose to offer full-stack development services, you can expect to earn between $16-$35 per hour, while back-end specialists often charge $20-$40. Keep in mind that these figures can rise with experience and the complexity of the projects you take on.

9. Custom software projects

You can use your software engineering expertise to create special software that's tailor-made for different businesses. Think healthcare, finance, and even small startups—they all want unique software to make their work better.

For example, a doctor's office might need a special system to keep track of patients, while a new online store could use software to manage its inventory. These are like custom tools for their jobs.

Getting into custom software projects involves more than just coding. You might need to understand a business's unique needs, plan how the software will work, and then put it all together.

As a software developer, you're looking at earning around $15-$30 per hour on average. However, your earning potential can grow depending on your specialization.

If you focus on User Experience (UX) design, you could make between $25-$39 per hour, showcasing your talent in creating user-friendly interfaces. Alternatively, if you specialize in a specific programming language like Python, then your hourly rate might reach around $20-$40, reflecting your proficiency in a sought-after skill.

Finding clients who need these custom solutions is where Upwork comes into play. You can create a profile there to showcase your skills. To build a portfolio, you can create mock projects.

For example, design a simple customer management system for a fictional coffee shop. Show how you'd organize customer data and orders. This gives potential clients a taste of your skills and creativity.

10. Tech blogging and writing

Getting into tech blogging means sharing your expertise while tapping into potential earnings through ad revenue and sponsored content. While the average blogger’s salary is $48,690, tech blogs may earn more due to their need for an expert voice, ability to tackle high-value subjects, and their in-depth insights.

Tech blogging involves creating content that appeals to tech enthusiasts, whether it's breaking down difficult concepts or reviewing the latest gadgets. Earnings come from sources like ads placed on your own blog, technical writing for other companies, or even setting up subscription models on your website for exclusive tech insights.

Tasks include writing with clarity, establishing yourself as a credible source, operating a content management system, and dedicating time to research and writing. Ultimately, tech blogging is a blend of knowledge sharing and entrepreneurial spirit, offering a chance to inform, entertain, and potentially earn.

11. Consulting

Offering consulting services involves being a tech advisor or mentor for businesses, guiding them through business decisions surrounding software selection, digital transformation initiatives, and system optimization.

Your tasks may include setting up client meetings, staying updated on the ever-changing technology landscape by keeping a close watch on industry trends, and explaining abstract ideas.

You might also recommend software solutions that align with a business's specific needs. This may involve suggesting tools or platforms that can enhance operational efficiency, or developing comprehensive strategies for improving existing technological systems.

Tech consultants can expect to earn anywhere from $12-$30 per hour, but you can earn substantially more depending on the scope of the project.

Tips for succeeding as a software engineer

Below are some helpful tips for success as a software engineer.

  • Set achievable goals. Software engineering can be overwhelming. Break down projects into smaller, achievable goals. This makes tasks more manageable while also giving you a sense of accomplishment.
  • Master one language before moving on. While there's a myriad of coding languages out there, focus on becoming proficient in one before jumping to others. Mastering one area of expertise equips you with a strong foundation to tackle others more effectively.
  • Prioritize testing and debugging. Writing code is only half the battle—testing and debugging are equally crucial. You’ll need to know how to regularly test your code to catch and fix errors early, ensuring your programs run smoothly.
  • Develop mock projects. To gain practical experience, create mock projects that mimic real-world scenarios. This helps you apply your skills, troubleshoot challenges, and showcase your work to potential employers.
  • Cultivate a network. Connect with fellow software engineers, attend tech meetups, and engage in online forums. Networking opens doors to learning opportunities, mentorship, and potential collaborations.
  • Embrace lifelong learning. Technology evolves rapidly. Keep up by dedicating some spare time to learning new skills and tools for your next project. Explore new languages, frameworks, and tools to remain adaptable and relevant in the ever-changing tech landscape.
