Project rating:

John has been absolutely great and outstanding to work with. He is professional, thorough, trustworthy and skilled. On a 5-star rating scale, I would rate his work as a 10. He went way above and beyond expectations working on a WordPress project with several Custom Post Types, Advanced Custom Fields, custom Plugin integration, with unique client requirements. He is very dedicated to a successful project and works extremely hard. I am very impressed.

Working with John these last couple of weeks has been a true pleasure. While I can focus on laying down the foundation of my website, getting the branding to my liking, hardening the LAMP stack underneath, John was working on customizing the User Experience (UX) portions of the website. Customizing the UX usually means getting hands on with PHP, CSS, JS; these languages are not part of my wheelhouse, and I'm glad that there are people like John and the service community of Codeable, where I can rely on to get these projects done without myself getting a crash course in web-development.The tasks that I asked John to work on involved customizing an existing theme, including changing the how the header behaves on certain conditions, building a new 404 page, mobile optimization, changing how the menu colors are managed, moving the search button, and he helped out with UX refinements with both desktop/laptop and mobile environments.If I were to do these tasks myself, they probably would’ve delayed my website launch by many weeks. With John here to assist me, I’m glad that my website can be launched as scheduled. I will be looking at John and the rest of Codeable in the future when I launch more websites.Thank you John, and Codeable.Franklin

John has been instrumental as one of our developers from the start to the go-live of the development of our site vilmer.no, which is an online community site for Norwegian Seniors. He has the right balance of implementing according to specification and, when appropriate, challenging our thinking with alternative scenarios and ideas based on his experience. John is always professional and walks the extra mile in delivering according to, and above, expectations. Any request has gotten a prompt answer, and all requirements have been followed up in a structured and professional way. I percieve John as honest, profesional, available and efficient. I would give my warmest recommendation to any company implementing wordpress based solutions considering John Leskas as a developer.John's tasks have been ranging from solution design, php development, theme development, integration and modification of open source plugins, css, javascript and general wordpress consulting.CTO, VilMer AS, Terje Øfsdahl
