Portfolio

Custom Zend Framework Application Utilizing Sendgrid SMTP API, PHP Mutlithreading , jQUery, AJax, Data-tables.

This application was developed single handedly by myself over the course of a year, though it does utilize an off-the-shelf admin template; template was highly customized based on client needs and UI aesthetics , and to incorporate more Ajax.
Email system features a multi-management role approval system (3 level) in which a campaign cannot be sent until passed all 3 stages of review.
Campaign Creation via a HTML syntax highlighter and automatic template variable insertion.
Template engine was completely custom built for simplicity and to stay lightweight based on the needs of the client.
Mail engine features pnctl utilization to spawn child worker threads to spread workload of processing each mail template and sending it to sendgrid, while also enabling workload to be spread across multiple processors- keeping system load down

Write some Software/ convert a template to a website

MIRV went above and beyond on the project. It was more difficult than initially anticipated but he followed through completely and did a phenomenal job. I would without a doubt hire him for another project in the future. He was easy to get in touch with and very honest. I would definitely recommend him for any project!
