    I am an enthusiastic, Denver based mechanical engineer with an extensive background in design for manufacturing and the appropriate use of additive manufacturing technology. With over 13 years of industry experience, I'm passionate about designing exceptional and innovative products. Before I started freelancing, I was a Sr. Mechanical Engineer at Aleph Objects and worked with a multidisciplinary team to produce several award winning 3D printers and accessories. Following that, I launched my own brand and line of niche products in the industrial 3D printing space, gaining experience with brand communication, crowdfunding and small scale production management. As a freelancer, I've had the opportunity to work with some fantastic clients producing everything from EV chargers and home battery systems to fitness equipment, college courses and medical devices. I run a small print farm in house for prototyping, including resin and oversized material extrusion printers. This helps reduce prototyping costs, speeds up the development process and allows the fastest iteration time possible when needed. Here are some of the services I offer: - Design Conceptualization (early stage sketches and ideation) - 3D Design - Photorealistic Product Renderings - Manufacturing Documentation *Bill of Materials (BoM) * 2D Drawings * Material and Manufacturing Method Advice * Tech Packs - Electronics Prototyping - Product Prototyping - Small Batch Production - Contract 3D Printing

A good freelancer will be upfront if something is outside of their skillset or if they can't fit the project in their schedule, and is careful not to overpromise. Wasting a client's time and money to deliver low-quality results isn't a sustainable business. If your project uses some technology I'm unfamiliar with, I generally don't charge for the time spent educating myself on it. I like learning new things, and it may be useful to know in the future.

How to Hire Top Open-Source Developers

How to hire open-source developers

It may seem counterintuitive to release your intellectual property to the masses for free, but open sourcing your software can help you attract top talent, bolster your branding, help your product gain market share as a platform, and leverage the collective experience of a global community of passionate developers.

So how do you hire open-source developers? What follows are some tips for finding top open-source consultants on Upwork.

How to shortlist open-source development professionals

As you’re browsing available open-source development consultants, it can be helpful to develop a shortlist of the professionals you may want to interview. You can screen profiles on criteria such as:

  • Technology fit. You want an open-source developer who understands the technologies you wish to open source.
  • Project experience. Screen candidate profiles for specific skills and experience (e.g., open sourcing a Python machine learning library on GitHub).
  • Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what it’s like to work with a particular open-source developer.

How to write an effective open-source development job post

With a clear picture of your ideal open-source developer in mind, it’s time to write that job post. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.

Job post title

Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample open-source development job post titles:

  • Need help open sourcing our material component library for Vue.js
  • Need help managing an open-source C++ library on GitHub
  • Building an open-source image-recognition library with TensorFlow

Open-source development project description

An effective open-source job post should include: 

  • Scope of work: From GitHub listings to feature development, list all the deliverables you’ll need. 
  • Project length: Your job post should indicate whether this is a smaller or larger project. 
  • Background: If you prefer experience with certain industries, software, or developer tools, mention this here. 
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

Open-source developer responsibilities

Here are some examples of open-source developer job responsibilities:

  • Design and develop open-source software
  • Host and maintain open-source projects on a remote repository (e.g., GitHub, Bitbucket, GitLab)
  • Write and maintain open-source documentation (e.g., README, contributing guidelines, code of conduct)
  • Monitor and handle bug reports, feature suggestions, contributor comments, and questions 

Open-source developer requirements and qualifications

Be sure to include any requirements and qualifications you’re looking for in an open-source developer. Here are some examples:

  • Application-specific programming language (e.g., C# for ASP.NET) 
  • Software development methodologies (e.g., Agile, Scrum, XP)
  • Familiarity with the SDLC (from requirements gathering to deployment and maintenance)
  • Code documentation

Open-Source Developers FAQ

What is open-source development?

Open-source development is the practice of releasing software source code to the public. Source code released under an open-source license can legally be inspected, copied, shared, altered, and extended by anyone who follows the terms of the open-source license agreement. 

More broadly, open source reflects an altruistic philosophy of collaboration and sharing, permitting people to modify source code and incorporate those changes into their own projects. 

How much does it cost to hire an open-source developer?

The first step to determining the cost to hire an open-source developer will be to define your needs. Rates can vary due to many factors, including expertise and experience, location, and market conditions.

Cost factor #1: project scope

The first variable to consider when determining scope is the nature of the work that needs to be completed. Not all open-source projects are created equal. Open-sourcing a simple web service will typically take less time than launching a new open-source web development framework. 

Tip: The more accurately your job description describes the scope of your project, the easier it will be for talent to give you accurate cost estimates and proposals.

Cost factor #2: open-source developer experience

Choosing the right level of expertise for the job is closely tied to how well you determined the scope of your project. You wouldn’t need an advanced programmer to maintain the code documentation and maintenance of your open-source project listing on GitHub. On the other hand, building an open-source software development platform from scratch will require a skilled programmer. 

Beyond experience level, you need to consider the type of experience the talent possesses. Generally speaking, an open-source developer is any developer familiar with the process of hosting a project on a remote repository such as GitHub, GitLab, or SourceForge. The following table breaks down the rates of the typical types of open-source developers you can find on Upwork. 

Rates charged by open-source developers on Upwork

Type of Developer

Description

Hourly Rate

Web development

Front-end development (e.g., HTML, CSS, JavaScript). Back-end development (e.g., databases, web servers, cloud storage). Experience with CMSs (e.g., WordPress), JavaScript frameworks (e.g., React), and/or app-specific frameworks (e.g., WooCommerce).

$30-120+

Mobile development

iOS app development (e.g., Swift, Objective-C, Xcode, Cocoa Touch). Android app development (e.g., Java, Kotlin, Android SDK, Android Studio). Hybrid app development (e.g., Flutter, React Native, Ionic).

$30-120+

Embedded systems

Programming languages (e.g., C, C++, Rust). Experience programming microcontrollers (e.g., Arduino), microcomputers (Raspberry Pi), and other hardware. Robotics, IoT, and operating-system-level code. 

$50-120+

Cost factor #3: location

Location is another variable that can impact an open-source developer’s cost. It’s no secret that you can leverage differences in purchasing power between countries to gain savings on talent. But it’s also important to factor in hidden costs such as language barriers, time zones, and the logistics of managing a remote team. The real advantage to sourcing talent remotely on Upwork is the ability to scan a global talent pool for the best possible person for the job. Location is no longer an obstacle. 

Cost factor #4: independent contractor vs. agency

The final variable regarding talent cost is hiring an independent contractor vs. an agency. An agency is often a “one size fits all” model, so you’ll often have access to a designer, a project manager, an engineer, and more. When hiring individuals you have total autonomy regarding who is responsible for which part of the project, but you’ll need to source each of those skills separately.

The trade-off between hiring individuals vs. hiring an agency is the level of administrative overhead you incur personally in coordinating tasks among all members of the team. Project scope and personal preference will determine which style is a better fit for your needs.

Open-Source Developer Tips and Best Practices

Choose the right open-source license for your needs

MIT, Apache 2.0, and GPLv3 are examples of other open-source licenses. Using a license is as simple as copy-and-pasting it into your repository. Open-source licenses differ from typical intellectual property licenses in that their goal is to help others contribute to and use your work without needing to seek special individual permission to do so. That said, these licenses still place restrictions on how source code can be copied, used, and distributed, usually to discourage abuse of the open-source license (e.g., someone charging others for free code you developed). 

For example, the GNU General Public License (GNU GPL) allows unlimited copying, distribution, and changes to the source code. You can even charge someone for software built partially with technologies open sourced under the GNU GPL, but only if you provide a copy of the GNU GPL so that others can see which part of your code is technically open source and available for free. This also gives you a chance to justify why you’re charging for your fork of the original source code. 

Write clear contributing guidelines

Maintaining an open-source project on a remote repository will of course become more challenging as more people become interested in your project. It helps to have clear guidelines for how developers can contribute to your project. You can include these guidelines in a README file along with your project description or in a separate CONTRIBUTING file. 

Contributing guidelines should communicate expectations for contributors such as:

  • Procedure for submitting a new feature suggestion
  • Bug report best practices
  • How to set up a test environment for a new feature
  • Types of contributions you’re looking for
  • Project roadmap
  • Contact information

The more detailed your CONTRIBUTING file, the easier it will be to manage your open-source project. 

Don’t forget to include a code of conduct

If your goal is to build a community around your open-source project, adopting a formal code of conduct can go a long way toward encouraging the type of behavior you wish to see within this new community. 

A code of conduct usually provides guidelines for how contributors and community members should interact with one another. You can establish community standards such as:

  • Demonstrating empathy and kindness toward others
  • Offering constructive criticism and receiving it gracefully
  • Abolishing derogatory language and harassment 

A code of conduct will give you a handy tool to use to moderate discussions about your project in your online communities. You can enforce it by banning offenders and removing comments on the grounds of violating your code of conduct. 

Don’t want to write your own code of conduct? There are plenty of drop-in open-source code of conduct documents available on the web (e.g., Contributor Covenant, Citizen Code of Conduct). Copy and paste the one that best suits your needs.
