About Me

Hallo! Mein Name ist Huzaifa Mustafa.

I am a Technical Director and Founder with over a decade of professional software engineering experience.

I began my career in 2014 building a broad, full-stack foundation. For the last eight years, I have focused exclusively on mastering the complexities of the Shopware ecosystem.

As the founder and technical lead, I use this combined "big picture" and "deep specialist" expertise to architect solutions and guide my expert teams at Elixent Digital and Synhex Solutions.

Elixent Digital

On the e-commerce side, I'm a Shopware 6 Certified Advanced Developer. My team tackles complex Shopware challenges. We've built over 150 custom plugins that help businesses scale.

Synhex Solutions

For everything else, my team builds custom web applications, mobile apps for Android and iOS, and scalable backend APIs from scratch.

I'm big on long-term relationships built on honest, straightforward guidance. My job is making sure every project gets expert architectural oversight so your business can actually grow.

Need a project partner? Reach out to me and I'll direct your project to the right agency for our collaboration.

E-commerce Integration

Slashing Import Times by 91% for 530K SKUs

A German e-commerce client struggled with a 33-hour product import process that throttled their catalog updates and operations. I engineered a custom Rubin API integration with optimized batch processing, database indexing strategies, and asynchronous handling to reduce import time to under 3 hours - enabling daily catalog refreshes and real-time inventory synchronization.

Automation

Zero-Touch Order Processing with Intelligent Automation

Manual order fulfillment created bottlenecks, shipping delays, and human error for a growing online retailer. I designed a fully automated fulfillment pipeline that integrates Shopware with warehouse management systems via webhooks and API orchestration - eliminating manual intervention, reducing order processing time by 85%, and cutting fulfillment errors to near zero.

Custom Plugin Development

Custom Tender Platform for Industrial Machinery Sales

An industrial machinery dealer needed to facilitate tender-based procurement but Shopware's standard cart system doesn't support bidding logic. I built a custom plugin architecture that transforms the checkout into a bidding interface, manages multi-party tender workflows, and integrates approval chains - enabling B2B clients to submit and track competitive bids directly through the storefront.

Key Technologies: Shopware 6, Custom Plugin Development, Symfony, Vue.js, MySQL, Entity Extensions
Multi-Platform Plugin

Cross-Platform Charity Donation System Architecture

Developed a custom charity donation plugin initially for Shopware 5, then rebuilt the same functionality from scratch as three completely separate plugins for Shopware 6, Shopify, and WordPress. Each platform required a native implementation - Shopware 6's entity system and DAL, Shopify's Liquid templating with webhook infrastructure, and WordPress's plugin hooks. Four distinct codebases, four different technical approaches, delivering identical checkout integration, donation tracking, and automated receipt generation. The challenge wasn't code reuse - it was reimplementing complex business logic four times while ensuring feature parity across incompatible platforms.

Key Technologies: Shopware 5/6, Shopify, WordPress, PHP, JavaScript, MySQL, RESTful APIs
Plugin Development

Enterprise Search Plugin from RC to Production with 100% Test Coverage

Took over maintenance of Findologic's Search and Navigation Plugin for Shopware 5, then rebuilt it from scratch for Shopware 6 starting from the initial RC version. Progressed the plugin through multiple Shopware 6 releases up to version 6.4, implementing complete unit and functional testing infrastructure achieving 100% code coverage. The open-source plugin handles advanced product search, intelligent filtering, navigation optimization, and analytics integration. Available on GitHub with comprehensive documentation and continuous integration.

Migration

Seamless Platform Migration Without Business Disruption

A small business faced the end-of-life for Shopware 5 but couldn't afford downtime or data loss during migration. I executed a complete migration to Shopware 6.6, mapping legacy data structures, rebuilding custom themes with responsive design, and ensuring plugin compatibility - delivering a modern, performant store with zero customer-facing disruption and improved conversion rates post-launch.

ERP Integration

Real-Time Inventory Sync for 300K+ Pharmaceutical SKUs

A pharmaceutical distributor required HIPAA-compliant ERP integration to manage complex product catalogs with batch numbers, expiry tracking, and regulatory compliance data. I architected a bidirectional sync system that handles 300,000+ SKUs in real-time, maintains audit trails for compliance, and prevents stockouts through predictive inventory alerts - ensuring zero fulfillment errors and regulatory adherence.

Huzaifa has worked for Findologic with me for about 2.5 years. Throughout the time span we worked together, it was great to see how Huzaifa grew from a fairly competent developer, to a developer who knew how to perfectly utilize his tools, knowledge, and passion to achieve what a client really needed. I had a very good experience working with him, he was always eager to learn, and got the grasp of new programming concepts very quickly. Overall I remember him as a professional developer who is passionate about the code he writes and a person with whom you can discuss very technical topics. Also on a personal level it was always great working with you. Keep it up!
