Self-taught full stack developer. Helped over thousands of clients to build their small to large scale websites. I love building high performance and scalable websites. Over the past few years, I have been heavily working on WordPress and Laravel. My top skills are: WordPress (oh, not to mention I used many popular plugins like: ACF, Gravity Forms, etc.), Laravel, MongoDB, MySQL, ElasticSearch, jQuery, Bootstrap, Redis, RETS integration, Plesk, WHM and many more! I occasionally do system admin tasks as I am managing plenty of servers running on CentOS. If you are lost in coding, need a hand or running out of ideas, feel free to reach out to me. I am not available for a full time hire but happy to help you with any kind of help you need with your projects.
