Unlocking the Potential of Freelance Developers: Their Impact on Your Company

Before diving into the hiring process, it’s crucial to recognize the substantial contributions freelance developers can offer to your startup. Their expertise in high-demand services and cutting-edge technologies empowers businesses of all sizes to enhance their online presence, create innovative mobile apps, and develop tailored software solutions. By leveraging their skills, companies can gain a competitive edge, meet customer demands, and optimize their operations effectively.

Startups seek developers for various reasons, including:

  • Establishing a Tech Stack

  • Staying within Budget
  • Building a Strong Team


However, hiring developers for startups presents several challenges, such as:

  • Recruitment Challenges


To address these hurdles, consider the advantages of hiring remote developers:

  • Access to a Global Tech Talent Pool
  • Expedited Recruitment Process
  • Flexibility in Team Structure
  • Cost-Efficiency
  • Greater Experience and Expertise


Notably, a remarkable 70% of U.S. SMBs have engaged with freelancers, underlining their widespread adoption. An impressive 81% of these businesses intend to rehire freelancers, attesting to their satisfaction with the value freelancers bring. These statistics underscore the pivotal role freelancers play in helping SMBs achieve their growth objectives.

7 Steps to Secure Your Ideal Developer for Your Startup

While there isn’t a one-size-fits-all approach to finding and hiring exceptional programmers, we’ve outlined several effective steps to help you in the process:

  1. Define Your Business Needs: Before you start hiring developers, clarify your project requirements and specifics. Determine the type of developer(s) necessary to meet your project goals.
  2. Choose the Hiring Model: Decide whether your project requires a project-based, dedicated team, or extended team model.
  3. Explore Talent Sources: Utilize online talent platforms like Toptal, Upwork, and Fiverr to discover qualified developers. Filter potential candidates based on their skillset, experience, and location if relevant.
  4. Review CVs & Portfolios: Assess the quality and caliber of their previous work to evaluate their technical capabilities. Understand the range of tools and technologies they are experienced with, and whether they are accustomed to working independently or with project managers. If you use services like Toptal, they may handle this vetting process for you.
  5. Engage with Shortlisted Freelance Developers: Schedule calls with potential candidates to gauge their personality and compatibility with your team. Inquire about their past experiences working on similar projects and assess their problem-solving abilities.
  6. Detailed Project Discussion: Break down your project and explain its objectives and functionality. Provide context by describing the project’s main purpose.
  7. Commence Development: Once you’ve selected a developer, initiate the work on deliverables. Establish regular check-ins and milestone discussions to ensure the project stays on track

What's the Price Tag for Hiring a Freelance Developer?

Breaking Down the Cost of Hiring a Freelance Developer

According to Upwork, the cost of hiring a freelance developer can vary significantly based on several factors. For a full custom site code, typically enterprise-level, involving building a website design from scratch with custom code and design elements, the average hourly rate ranges from $75 to $150 or more. Conversely, a basic one-page site, such as a lead-gen page or landing page, will cost an average hourly rate of $15 to $40 or more.

The following factors play a crucial role in determining the cost of hiring a freelance developer:

  1. Skill Demand: The specific skills in high demand can impact the hourly rate.
  2. Project Complexity: The complexity and scope of project requirements influence pricing.
  3. Geographic Location: The location of qualified candidates may affect rates.
  4. Expertise and Experience: Developers with extensive expertise and experience often command higher rates.
  5. Past Work and Brand Associations: Developers with a track record of working with well-known brands may charge more for their services.

Essential Skills to Seek When Recruiting a Startup Developer

As eloquently put by the distinguished software engineer, Martin Fowler: “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.”

This quote underlines the significance of not only possessing fundamental technical knowledge but also the skill to produce clean, maintainable, and comprehensible code. Employing developers who embrace this perspective can significantly enhance project success and team efficiency. When seeking a freelance developer, it’s crucial to identify someone with a broad spectrum of technical competencies, which may include:
  1. Coding Languages:
  2. Web Frameworks:
    • ReactJS, Angular, and others Systems Architecture
  3. Database Technologies:
    • MySQL, MongoDB, and others Cloud Computing
  4. DevOps Tools:
    • Docker, Kubernetes, and more

The practice of hiring remote and freelance developers is gaining widespread acceptance, with numerous websites claiming to be the optimal resource for finding such talent. Each platform comes with distinct structures and assurances, so it’s essential to be comfortable with a specific site’s parameters. We have compiled a list of recommended top sites for locating developers with diverse skills, but how do you determine which type of site aligns best with your requirements?

Services Specializing in Talent Matching

Not everyone possesses the technical expertise to screen and validate developers’ qualifications. Platforms like Toptal and Hired take on these responsibilities and exclusively endorse top-tier developers. Leveraging talent-matching sites allows you to efficiently and swiftly discover developers tailored to your project’s requirements. This not only saves time and resources but also guarantees that your developer team possesses the qualifications necessary for project success.

Marketplaces for Freelance Developers

Marketplaces provide a platform for skilled developers to showcase their services. While most of these sites do not perform extensive developer screening or vetting, some do offer such services. If you are working under time constraints or lack the confidence to evaluate a candidate’s qualifications independently, this type of site may not align with your needs.

Job Boards for Developers

If your preference is to post your project description and job openings, consider utilizing a developer job board. These platforms enable interested developers to submit applications, and they may also offer assistance in the selection process.
