Ahmad Hasan
E-commerce Software Engineer
Architecting end-to-end commerce ecosystems — Shopify, WooCommerce, custom business software, ERP integrations, POS, and automation.
E-commerce Software Engineer specializing in architecting and integrating complete commerce ecosystems. With over 6 years of production experience, I bridge the gap between customer-facing storefronts and mission-critical business operations — from high-converting Shopify 2.0 and WooCommerce architectures to custom Laravel backends, real-time POS systems, and bi-directional ERP integrations (including Odoo and SAP). Focused on high availability, data consistency, sub-second speeds, and automated retail workflows for remote-first and international teams.
Core Engineering Principles
E-commerce is more than an online catalog. I design software that seamlessly links digital sales to ERPs, physical branches, warehouse inventory, and automated fulfillment.
Eliminating reliance on bloated third-party monthly apps by authoring clean Shopify Liquid sections, native metaobjects, and optimized Next.js server components.
Webhooks and API requests can fail or duplicate. I implement Redis queues, HMAC validation, exponential retry policies, and idempotency keys to guarantee data integrity.
Preventing negative inventory counts during flash sales or multi-branch POS checkouts using database-level transactional row locks (SELECT FOR UPDATE) and ACID principles.
International Remote Ready
Equipped for remote collaboration across European, Gulf, and US timezones. Experienced with asynchronous communication, Git pull request workflows, documentation integrity, and agile sprint delivery.
