My extensive experience in developing and maintaining application modules using Core PHP, Python, MYSQL, HTML, CSS, Bootstrap, JQuery, and Javascript, I believe I am well-suited for this role. I would like to highlight some of my key accomplishments in my previous roles: . Designed a website QA automation module in Python using Selenium that significantly reduced the workload of the QA team by 85 percent. This module is now being used for testing website quality and running different test cases. Single-handedly managed the Hello Expert Module and their payments, while also developing a "Sell Document" feature that generated a total profit of almost $1500 per month for the company. Created flowcharts, layouts, and documentation including flow diagrams and network diagrams to identify requirements and solutions. Tested applications and features implemented by other developers by analyzing client requirements and system specifications, preparing test scenarios, documenting test cases, and performing testing on QA and Staging environments using Selenium. This resulted in cutting down deployment time cost by 70 percent. My technical skills include expertise in PHP, Python, Django, MySQL, Github, HTML5, Javascript, and JQuery. Thank you for considering my application.
