Entrepreneur with many hats, focused on ES, HW and CV.

I'm currently a full-time startup managing director with main focus in technology, where provide two solutions: 1) driving behavior evaluation based commercial fleet management 2) rolling stock based digitalized railway infrastructure inspection based on our dual edge-AI camera and enterprise cloud platform. I spend most of my time on managing developers or developing myself for the industrial design, AI engine, computer vision application, hardware (10 layer PCB with 3 subsystems), imaging system and camera, cloud application and a custom Linux kernel where I develop some of the basic kernel drivers as well business development and some communications. Last year I had 5 masters thesis students in - AI, embedded systems and cloud - where I was their industrial advisor and indeed that was great fun for me. Now that I lack that opportunity, I joined Codementor to have similar engagements. I hold a double masters in Embedded Systems with Innovation and Entrepreneurship from KTH Royal Institute of Technology and Technische Universität Berlin where I held an excellence scholarship. I'm bilingual in English and Turkish. Also can communicate in German, Spanish and French in a basic level. You can check my Codementor profile here: https://www.codementor.io/@tolgavarol

Frequently asked questions

C is one of the world's oldest mid-level programming languages, going back to the early 1970s. Initially, its main point was to make the UNIX operating system compatible with multiple devices. However, the fact that it contained many valuable features of other popular programming languages at the time allowed it to become dominant quickly and spread to everything from supercomputers to embedded microcontrollers.

Most of today’s programming languages are based on C, including Python, C++, C#, JavaScript, Java, and others. C is used for many embedded systems and system application development. Also, MySQL was built on C++ and C, and the same goes for operating systems like Windows and Apple OS X. In the IoT era of embedded software, it’s gained even more use.

C is a middle-level language combining many features of low-level and high-level languages. For instance, it can be used for making kernel and driver scripts- low-level programming – but it also supports scripts for software applications, meaning it’s usable for high-level programming too.

Today, C is mainly used for embedded software. Its features like C compilers, dynamic memory allocation, deterministic resource use, and access to machine-level APIs make it an ideal choice for embedded systems.

Though, it’s still a general-purpose language – meaning it works on games, enterprise apps, graphics, etc. It’s also great for swiftly implementing data structures and algorithms, making it an excellent choice for applications that perform higher-level calculations – like Mathematica and MATLAB.

The length of a project depends on many factors, including the scope of your project and the technical complexity of it. When you post a freelance C project request on Codementor, you’ll have the option to indicate when you’d expect the project to be completed. We suggest chatting with the interested developers to ensure both sides are on the same page. For more information on how to post a freelance C request on Codementor, check out our article.

We don’t charge anything when you post a freelance hiring request for C developers! You’ll have the chance to determine what the budget for your project is when you post the request. You’ll only need to pay the developer if you’re 100% satisfied with their work. Please know that Codementor charges a small service fee when a developer completes the job.

C developers work on code that gets integrated into kernel modules, base operating systems, and embedded systems that support other higher-level languages. In modern programming, C is a pretty niche language used only by highly specialized developers who usually work on embedded systems.

As such, C developers often identify CPU bottlenecks, implement performance modules, and fix various bugs. A modern freelance C developer needs to be proficient in C and C++. Also, they need to be familiar with code versioning tools like Git and have strong problem-solving abilities. For developers working on embedded projects, knowledge of low-level hardware and systems design is a must – as well as knowledge of the standard C library, defined by ANSI and ISO.

Also, embedded engineers usually have a firm grasp of real-time environments, low-level threading, and memory management. Depending on the project, they might also have to write native modules for other higher-level languages like Python or Node.js.

We do a comprehensive technical and communications screen of all C developers at Codementor. Our network includes book authors, popular open source contributors, top Stack Overflow users and engineers at top tech companies. In addition, to continually ensure the quality of our freelancers, we regularly check in on existing C developers’ user satisfaction rates.

Suppose you’re looking for a freelance C programmer to join your project. In that case, you need to ensure they’ve got the proper technical knowledge – and, just as importantly, experience working on similar projects, so you can be sure they’re a great fit.

Here are a couple of C interview questions you can use to test all of that:

  • What is C used for in modern programming?
  • What are mid-level programming languages?
  • What are the main advantages of C?
  • What are tokens?
  • How are the scanf() and printf() functions used?
  • What C projects have you worked on before?
  • What embedded software projects have you worked on before?
  • How long have you worked as a freelancer?
  • How many other clients are you working with at the moment?
  • What are preprocessors?
  • Explain a recursion in C.
  • Why is n+1 slower than n++?
  • Explain what an l-value and an r-value are.
  • How do you avoid memory leaks?

As a platform, we strive to ensure you’re always happy with your C project’s results. If you’re unsatisfied with the results, you can choose to get a refund for the project. Additionally, you can contact our support team should you need any further assistance with your project.
