Senior E-commerce Developer with 9+ years of hands-on experience in building and scaling high-load online stores. My core expertise lies in architecting complex backend systems for Magento (Adobe Commerce) and Shopify, ensuring they are secure, performant, and future-proof.
As a former Magento Development Instructor, I maintain the highest standards of code quality. I specialize in turning complex business requirements into stable technical solutions.
Key Expertise:
• Magento 1 & 2 (Adobe Commerce): Expert-level data migrations, version upgrades, and performance tuning for large-scale databases.
• Custom Business Logic: Proven track record in developing advanced features like real-time dynamic product availability and tiered VIP loyalty programs.
• Shopify: Custom Liquid development, rapid MVP launches, and seamless 3rd-party integrations.
• Tech Stack: Deep knowledge of PHP (Symfony, Yii2), Python, Docker, and CI/CD workflows.
Efficiency Advantage:
I integrate AI-assisted development tools into my workflow to accelerate delivery speeds by 2-3x. This allows me to handle bug fixes, refactoring, and feature development significantly faster than traditional methods while maintaining Senior-level architectural integrity.
I focus on business ROI and long-term stability. Let’s connect to discuss how we can optimize your e-commerce infrastructure.
