    I am a highly motivated software developer with three years of work experience and a Master's degree in applied computer science. At work, I've learned valuable things about full-stack development, in particular with C++, SQL and SOAP on the backend and with Java, JSF and Primefaces on the frontend. After that I went back to studying with a main emphasis on JavaScript/TypeScript based applications and Web security, in particular with OAuth 2.0 and JSON Web Tokens. Currently, I prefer to work with Node.js combined with ReactJS, Express.js and MongoDB, but furthermore, I am always passionate about new technologies. Over the years I came in contact with a lot of transferable concepts and with technologies, I could pick up again.

    I am a full-stack web developer with over 9 years experience in the industry. A solid part of the projects were connected with the cloud-based ecommerce platforms like Shopify, Bigcommerce and Amazon. Shopify is my favourite one that's why I know this platform backwards and forwards and have my strongest expertise here. Around 30 public and private Shopify apps were built by me or with my help as a consultant. Many of them are published in the app store and have more than 100K active installs. Although the main expertise is Shopify, I can efficiently work on other projects as well, because the tech stack is standard enough for any web project. Please find the list of my skills below: ✔ Ecommerce Platforms: Shopify, Amazon, Bigcommerce ✔ Server side: Node.js (express, koa, next), Typescript, PHP (Laravel, Zend Framework, CakePHP) ✔ Databases / storages: MySQL, PostgreSQL, MongoDB, Redis, ElasticSearch ✔ Queues: RabbitMQ, SQS ✔ Web servers: Nginx, Apache ✔ Client side: HTML/CSS/SASS/LESS, Javascript ES5/ES6, jQuery, React, Next, Webpack, Vite ✔ CI/CD: Jenkins, SemaphoreCI, Bitbucket Pipelines, Terraform, Docker, Docker Compose, Git ✔ Unit testing: PHPUnit, Codeception, Mocha, Jest ✔ Cloud computing: Amazon Web Services, Serverless During my career I was working on different size projects and had different roles including back-end, front-end, lead developer and architect. 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.

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.

    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.

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.

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.

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
