Software Engineer, Mentor, and Consultant (ex-Microsoft, ex-GoJek)

Website: https://linktr.ee/YoKulGuy --- I'm a realist, aspiring general system thinker, and software craftsman. Despite specialists giving much contribution and productivity to society, general system thinkers and their general system thinking can help us solve the second-order effect of human creation. As a society, we build civilization; we build skyscrapers, aeroplanes, gadgets, and all the advancements in technology, but we overlooked the second-order effect of our creation. Global warming and gadget addictions are an example to name a few. The more people adopt general system thinking, the more we can achieve a better society and brings our world to the next thousand years. I do research and craft code as my way of expressing my idea and belief. I crafted a scientific computation tool and instrument to help researchers do better research when I was in college. I'm currently leading a team in a startup called Mekari to empower businesses in Indonesia. I previously worked at Midtrans, enabling software developers to be more productive and better empower commerce through technology. I write production code in Elm, JavaScript, Bash, Ruby, and Java. In 2020 I did functional programming on Elm and built a community around it. Feel free to reach out to me if you are an Elm user!

Easy 🙂 **Backstory** I started programming in 2018 after my mentor told me that it really fits the way I think. Before I started I was learning marketing, working in Facebook Ads and Shopify Stores (with Google Analytics, VWO, and other website optimization softwares), I was more interested in automation, and building to do tasks only once. I started at first learning Python for automation (which is still my primary language and what I really enjoy coding in). Eventually, I learned that by itself, Python isn't that sharable if you want other non-coders to use the my apps, so I grew my way into web development, diving deep into Django, HTML & CSS, building multiple sites with only those to get experience, for example: - My website: https://www.zackplauche.com/ - A mini app I built: https://www.dollarperhourcalculator.com And more :) Then eventually learning JavaScript and the Vue.js framework to take my websites, designs, and User Experiences to the next level, building at first simple apps like my DollarPerHour Calculator (https://zackplauche.github.io/DollarPerHourCalculator/), and more advanced ones, like the current one I'm developing (still in progress, but it's the biggest app I've ever build, using both Vue.js and Django). I've been teaching programming since 2019, and my students have loved me. I have students I work with that have been working with me weekly since I first started (more than 5 years now!). They helped me keep both my coding and teaching career sustainable as I was helping them with their issues, training them to be effective developers, starting my own software agency, and building my own apps. I'm extremely grateful to my students and truly care about and do my best to support their success in whatever their endeavors.

Frequently asked questions

JavaScript is a programming language that is used across almost the entirety of software development, from front-end engineering to mobile development and even for game development. It is so popular, in fact, that it continues to be the most commonly used programming language, according to the annual Stack Overflow survey; 2022 marks its 10th year in the top spot.

JS, as JavaScript is often abbreviated, is used on a majority of websites, up to 98% actually. Just about any visit you make online will involve JavaScript, a language that traces its origins back to the mid-90s and the once-great Netscape company, makers also of the now-defunct Netscape browser.

JavaScript is quite versatile, but it is most often used to add dynamic content and features to otherwise static web pages. It is regularly used for calling APIs to serve fresh content, storing values, manipulating data, and a whole lot more.

Every modern web browser includes a JS engine to parse code, but there are also runtime environments such as Node.js. JavaScript frameworks help software developers by offering “building blocks” of pre-built code to use for routine tasks.

Because of its ubiquity and necessity in just about everything we do nowadays, particularly online, you’re probably going to be using it for your project. So, whether you choose a JavaScript freelance developer or not, you’ll likely need a developer who’s well-versed in JS.

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 JavaScript 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 JavaScript request on Codementor, check out our article.

We don’t charge anything when you post a freelance hiring request for JavaScript 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.

When hiring a freelance JS developer, consider the depth of their JavaScript knowledge. If you will require them to work with JavaScript almost exclusively, they’ll need a good understanding of the entire ecosystem, with some knowledge of React, Angular, Node, jQuery, Typescript, and other technologies. If you’re looking for a good well-rounded developer, you may choose someone with less depth in JavaScript but more breadth across other areas of engineering.

Aside from technical skills, be sure your prospective freelance JavaScript programmer has the soft skills to be a good fit, as well. Every solid coder you hire should be a great analytical thinker, problem solver, and decision maker. Plus, you’ll want to check to see if they have the experience and abilities to work well with you and your team as a remote hire.

We do a comprehensive technical and communications screen of all JavaScript 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 JavaScript developers’ user satisfaction rates.

On the technical side of things, ask questions about JavaScript and any other technologies you may want them to utilize, of course. However, dig a little deeper with your questions. Use your interview questions to understand how they go about solving problems and what their thought process is like.

Ask questions to delve further into their soft skills and remote abilities, too. Use the interview to get a sense of how well they communicate, and try to work out how well they’d do managing their own time and staying organized, as well.

As a platform, we strive to ensure you’re always happy with your JavaScript 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.
