Jase Warner

Creative Front-end Developer

I am a freelance front-end developer based in London. I love code, design, and making sounds. Since switching from full-time to freelance over 5 years ago, I have worked on a variety of front-end and full stack contracts in London.

My go-to programming language is PHP and I specialise in building WordPress and Shopify websites from the ground up. My skill set also includes React, JavaScript (ES6), HTML5, CSS3, SCSS, C#, Gulp, Webpack, BEM methodology, Bootstrap 4, Git, Less, C#, jQuery, Liquid, HTML responsive emails, Sketch, Zeplin, Photoshop, Illustrator, and InDesign.

I pride myself on writing tidy and robust code. Working in a collaborative environment suits me to a T.

I have been dealing with web designers for a long time now and I have never worked with someone as fast, transparent, fair, involved and trustworthy! I feel really lucky for having worked with him, knowing I had to deal with a lot of people who took advantage of my lack of technical knowledge. Super thankful! My website works perfectly after he redesigned it in a week only, my sales have gone up considerably as well. Best experience, couldn't be happier!

Anissa Kermiche, Founder, Anissa Kermiche

We needed a freelancer to come in and take on a project head on and who could do it independently, Jase did just that. Really helpful and fitted easily into the team. He was willing to talk to the client and help support myself as the Account Manager with any questions we had. We would definitely look to using Jase again in the future. Thanks for your work!

Holly Clemens, Account Manager, Mediablaze

Working with Jase has been really great. Our brief was simple: Make our new website- clear and modern. We are very happy with both, creative and technical solutions Jase came up with. The process was seamless and delivered above expectations. Also appreciate his ability to assist with updates and future proofing methods. A great partner!
