    I'm one of the highest-rated WordPress developers on UpWork - carrying a "Top-Rated Plus" badge and plenty of reviews from highly satisfied clients. Efficiency and quality are my priorities - typically delivering ahead of schedule and above & beyond client expectations. I'm fast and thorough and have seen just about everything you can imagine within the WordPress framework. I have been immersed in the fields of web development, design, and digital marketing for over 10 years. My specific expertise lies in WordPress web development, site migrations, speed optimization, site security, plugin & theme development/customization, UX / UI design, eCommerce and SEO. I'm an all-around talent working on both the frontend and backend on every job I'm involved in (saves you hiring a designer, and then a developer, and then a project manager, etc.). I can handle any web development or design project regardless of scope. Some of the plugins/themes that you don't have to buy since I have the agency/lifelong offerings: - Borlabs Cookie (for GDPR compliant site) - WPML (for multilingual site) - WP All Import (for importing and exporting data) - Elementor Pro (if i work with page builders then mostly with Elementor) - Impreza theme (Popular theme with own page builder) - JetPlugins by Crocoblock (Plugins for Gutenberg and Elementor) - All in one WP migration (for quick migrations of websites I have the addon plugins) - My self developed table of contents plugin (the best TOC plugin. All other TOC plugins have issues) - Presto Player (for self hosted Wistia like functionality) - ACF Pro …

    Creating top-notch Drupal sites is what I do best. With more than 10 years of experience in Drupal, I’ve delved deep into its core APIs and numerous contributed modules, covering almost every aspect of Drupal development. My approach is always about doing things the 'Drupal-way' — ensuring your site is not just built, but built to be easily extendable and maintainable. I genuinely love what I do. There's a real satisfaction in doing a job right, in seeing clients happy with the work, and feeling proud of what I've achieved. I understand that my skills are my most valuable asset, so I'm always on the lookout for new knowledge and experiences that can enhance my expertise. Whether it's a complex task or a unique problem, I'm ready to tackle it head-on and deliver results that exceed expectations. With me, you're not just getting a developer; you're getting a dedicated partner who's committed to making your Drupal site the best it can be.

    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!

So far, I worked with Laravel, express.js, feather.js, socket.io, Vue.js, React.js, and React Native Web as a web stack. On the other hand in mobile, I am using Native Android, IOS, Flutter and React Native to develop applications. I'm addicted to clean workflow using testing frameworks like Karma, Mocha, and Tape.

Each project is different but I do all my best to build as robust and scalable solution as possible within a given budget. I am motivated, responsible, punctual person and attentive listener. Always dedicated to work and ready to defend own opinion if I believe it is more efficient and better for the project success. Please take a look at my work history for comments from other clients.

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
