Ivan Kostic – Founder & CEO of webiFed

Ivan Kostic

My name is Ivan Kostic, a founder of webiFed. I’m a Top Rated Plus freelance web developer on Upwork. You can check what my clients say about my work at any time.

Working with front-end at most, my specialty is converting mockups and designs (PSD/Sketch/Figma/AI) to responsive HTML5 & CSS3 code, especially for WordPress custom themes. Personally, I don’t recommend just customizing free/premium bloated themes, I would rather go and code exactly the things suited for your needs and your site. So, building many websites with WordPress had a huge impact on growing my freelance web developer career further. I also created a number of WordPress widgets, including some custom PHP & MySQL projects from scratch like, for instance, a betting script. I’m producing robust, well-commented, and clean coding only – no hard-coding and messy coding!

You must not mistake in your web development choice!

I have 10+ years of experience in making the web a better place, including two years of working experience in local companies. Things have changed a lot in web development in recent years, so in order to keep my freelance web developer career alive, I need to follow the latest trends and methods.

When I was starting, websites were viewed mostly on desktop devices, which isn’t the case anymore! “The Responsive website era” has begun many years ago, and coding for mobile devices is a must today! Also, coding languages evolved, so I’m educated with the latest versions of HTML5, CSS3, JS (ES6). Actually, I write my CSS as modular SCSS in WebPack workflow, as I moved from Gulp recently. More about this will be written in my blog, which I would strongly advise you to follow. It’s unlikely that you can ever stop learning things as a freelance web developer. Therefore in my spare time, I’m exploring one of the most popular JavaScript frameworks today – ReactJS. Coding web apps are in my long-term plans.

Knowing visitors’ intentions is helping me to create astonishing user experience (UX) interfaces, that will keep visitors engaged in your website. That’s one of the most important factors in SEO. You need returning visitors/customers for your websites, and awesome content in order to get succeed in Google rankings. As I already stated, I’m delivering SEO-ready code, and also have a bunch of SEO advice to help you to grow your business to the next level. Being on the web for so many years makes me the SEO expert as well. Google Search Console is my best friend for playing within Google’s rules for site ranking.

We all know that good communication is key for every kind of work, so don’t hesitate to write to me anytime!
