At MontyPay, I integrate the payment gateway with Shopify, WooCommerce, OpenCart 4.x, and Drupal Commerce. I build REST API connections and webhook/IPN handlers that keep order and payment status in sync.

I deliver Hosted Payment, S2S Direct Card, Apple Pay S2S, and Hosted Payment Fields integrations. I guide merchants from requirements and sandbox testing through go-live, and troubleshoot issues using Postman, logs, and Jira.

At Presentail, I integrated the e-commerce platform with CRM, warehouse, and marketing systems. I also built automated workflows with Make.com and Zapier and real-time inventory and order-processing pipelines across thousands of SKUs.

On the Abed Tahan Website project, I built an automated product integration that imported 4,500+ products and synced them three times a day. Earlier, at Bouncing Pixels and Codi-Tech, I developed websites and e-commerce and financial tracker systems.
