Convert - NodeJS, React, MySQL, JavaScript As a Full Stack Developer on the Convert.com (http://Convert.com) project, I built & optimized an A/B testing tool using React, Node.js, & JavaScript. On the frontend, I developed interactive, high-performance UIs with React, ensuring seamless experiment creation & real-time result tracking. In the backend, I implemented RESTful APIs, authentication, & experiment data processing using Node.js. I optimized performance with caching, asynchronous execution, & scalable architectures. Additionally, I ensured security, role-based access control, & seamless third-party API integrations for analytics & reporting.

Ticket Create/Print SaaS Tool Revamp We encountered a dysfunctional online SaaS software for ticket printing, which had become useless due to the outdated flash-based ticket editing software. To rectify this, we rebuilt the editor using AngularJS and seamlessly integrated it with the product page, making online editing functional and valuable. As part of the project, we also performed upgrades to the Laravel versions and system packages. MongoDB was utilized for storing all ticket information, while MySQL, integrated into the Laravel software, handled tasks such as authentication and customer information management.
