Marin is a full-stack web developer who, for the past few years, has been building custom websites and apps for various agencies. A constant about Marin is his dedication to reaching targets on time but not at the cost of the quality of output. In his mind, the given timeframe, the quality of the product, and the client’s satisfaction come first. Marin is looking for long-term projects where he can grow while realizing the client's vision.

WordPress Theme Development

During the past two years, I've created custom WordPress themes and plugins as an outsourced developer for other agencies and therefore I cannot showcase them in my portfolio.

WordPress eCommerce Website

I built, as an outsourced remote developer, a WordPress custom eCommerce site that connects customers with suppliers. I developed the whole eCommerce process, from the product to cart and checkout. I also developed a front-end dashboard for administrators, customers, and suppliers allowing them to handle orders, quotes, and shipment tracking. Payments are done via Square and everything was connected to Xero for online accounting.

WordPress Video Training Site

I developed a custom WordPress video training site that had different payment plans, video progress tracking, and a dashboard for individuals to modify their details, update their subscription, and look over their video viewing and commenting history. Payments are done via Stripe.

JobAdder WordPress Plugin

I developed JobAdder WordPress plugin for recruitment & HR client. Used JobAdder API and cron to import and maintain available jobs. I also developed front-end job apply form, job listing with location, keyword and category filter.
