    My passion is making ideas come to life, be it working solo, as part of a team or leading a team of fellow developers. Throughout my 5 years of development experience, I worked everywhere from startups to big companies, building products from the ground up or implementing new features. Also relevant to my set of skills is that - previously to becoming a developer - I worked as product manager for some of the biggest tech companies in the world, which still helps me to have a more holistic view of the whole work that goes into making a successful product. My go-to technologies are React and Node.js, and I have completed a wide range of projects using them. Those are not the only two libraries/frameworks I'm familiar with though, and I'm always happy to discuss my client's needs and find the best solutions for them. I consider myself creative and hardworking, as my stats show. If you liked my profile so far, drop me a message and we'll discuss how I can be useful to your project.

    I am passionate about bringing websites to life for my clients that reflect their brand, vision, and personality. One of the things I take most seriously is providing support throughout the entire journey and communicating clearly through the process! I have built a wide range of websites related to the following industries: psychology, authors, basketball leagues, fitness studios, coffee shops, equipment rentals, home defense, energy work, etc. Any chance I have an opportunity to work in a new field, I consider it a chance to become a better version of myself as I get to learn about something new! Webflow has become my CMS of choice! It allows me to build the client a completely custom design, while also giving the client the ability to maintain the site themselves moving forward! When I build a new website, I make them modern, clean, and bold. Depending on budget, I also offer branding, logo, and design packages as well! Reach out if you want to partner up and begin the journey of developing a new website with me!

    I have 15 years of experience working with Drupal and 20 years of experience with full stack Web development. I've worked almost exclusively with Drupal for the past 6 years. I currently manage 2 large and several small Drupal sites in versions 7, 8 and 9. I have also recently taken an intensive course to shore up my knowledge of Drupal 8. Led by a Drupal Grandmaster and former Acquia engineer, this rigorous course taught me common usages and Drupal 8 best practices for the following technae: Composer, Drush, Drupal Console, Git commands & workflows, SASS, Twig, custom module development and how to work within a remote development environment.

How to Hire Top JavaScript Developers

What is JavaScript?

JavaScript serves as the dynamic powerhouse of web development. If HTML is responsible for the structure of a web page and CSS is responsible for the style, JavaScript breathes life into the experience by enabling interactivity and responsiveness. Whether it's implementing complex functionalities, handling user interactions, or updating content dynamically, JavaScript plays a pivotal role in crafting modern, dynamic web applications. A skilled JavaScript developer is critical for unleashing the full potential of web technology.

How do you hire a JavaScript developer?

You can source JavaScript development talent on Upwork by following these three steps:

  • Write a project description. You’ll want to determine your scope of work and the skills and requirements you are looking for in a JavaScript developer.
  • Post it on Upwork. Once you’ve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
  • Shortlist and interview JavaScript developers. Once the proposals start coming in, create a shortlist of the professionals you want to interview. 

Of these three steps, your project description is where you will determine your scope of work and the specific type of JavaScript developer you need to complete your project. 

How much does it cost to hire a JavaScript developer?

The first step to determining the cost of hiring a JavaScript Developer will be to define your needs. Rates can vary due to many factors, including expertise and experience, location, and market conditions.

Rates typically charged by JavaScript Developers on Upwork are:

  • Basic Developer: $15-50+ per hour
  • Intermediate Developer: $35-100+ per hour
  • Advanced, Full-Stack Developer: $100-150+ per hour

Learn more about the cost of hiring JavaScript Developers on Upwork.

How do you write a JavaScript developer job post?

Your job post is your chance to describe your project scope, budget, and talent needs. 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 JavaScript developer job post titles:

  • Seeking a full-stack JavaScript developer (MEAN)
  • Building a universal JavaScript app with React and Node.js
  • JavaScript developer needed for an ecommerce website

Project description

An effective job post should include: 

  • Scope of work: From dynamic single page applications (SPAs) to progressive web apps (PWAs), 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 specific technologies, such as React Native for mobile apps, mention them here. 
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

JavaScript developer job responsibilities

Here are some examples of JavaScript developer job responsibilities:

  • Write scalable, testable, well-documented JavaScript code
  • Build, test, and deploy front-end features
  • Use JavaScript on the back end for APIs and server-side logic
  • Optimize apps for cross-platform compatibility and performance

JavaScript developer job requirements and qualifications

Be sure to include any requirements and qualifications you’re looking for in a JavaScript developer. Here are some examples:

  • Web fundamentals, including HTML, CSS, and JavaScript
  • Proficiency in the latest version of ECMAScript (a JavaScript specification)
  • JavaScript frameworks such as Vue, React, and Angular. 
  • Back-end technologies such as Node.js, Express.js, and Horizon
