Platforms
I build systems
that scale.
Back-end developer with deep roots in the PHP ecosystem — from raw PHP to modern frameworks like Symfony and Laravel, and enterprise e-commerce platforms like Magento and OpenCart.
My speciality is payment gateway integration — connecting web and mobile applications with Stripe, PayPal, Paymob, and regional Middle Eastern processors. This has been the backbone of most projects I've shipped over the last nine years.
I recently expanded into Flutter & Dart, which lets me deliver complete products — backend API to mobile app — for clients who need a full solution, not just half a stack.
I'm equally comfortable leading a build solo or working inside a cross-functional team. Whether you need a senior engineer, a freelancer to ship a feature fast, or a consultant to audit your payment flow — I'm ready.

Books I've
reviewed.
Continuous learning is part of the craft. A curated selection of technical books I've read and reviewed — covering PHP, Symfony, Magento, Flutter, and software architecture. These are the books I recommend to every developer I mentor.
Mastering Test-Driven Development with PHP 8
Written for PHP developers from beginners with basic syntax knowledge to intermediate developers seeking to adopt TDD and improve their application architecture. Practical, grounded, and immediately applicable.
Symfony 6: The Fast Track
The definitive guide for mastering modern Symfony. Sharpened my understanding of the framework's internals — from the HTTP kernel to attribute-based routing. A must-read for backend engineers.
PHP 8 Objects, Patterns, and Practice
The most thorough treatment of OOP and design patterns in PHP. Covers match expressions, named arguments, enums, and fibers. I reference this book weekly when architecting services.
Flutter in Action
My gateway into Dart and Flutter. Explains widgets, state management (Provider, BLoC, RxDart), and platform channels with clarity. Highly recommended for backend developers transitioning to mobile.
Domain-Driven Design in PHP
A code-first approach to DDD demonstrating hexagonal architecture, CQRS, and event sourcing with Symfony and Laravel examples. Transformed how I structure complex e-commerce domains.
Clean Code
Timeless principles that translate directly from Java to PHP. I enforce these standards in every codebase I touch — from Laravel services to Magento modules. Re-read annually.
Magento 2 Development Beginners Guide
The most accessible entry point into Magento 2 module development. Covers DI, plugins, events, and the UI component system. The architectural foundation remains invaluable even for 2.4+.
Let's build
something great.
Open to senior PHP development roles, freelance projects, and consulting — full-time, part-time, or contract. Whether you need a Symfony/Laravel backend, a Magento store, or a Flutter mobile app — I'd love to hear about your project.
