About

I build e-commerce
systems that scale.

I'm an experienced back-end developer with a demonstrated history of working in the internet industry. My core strength lies in PHP ecosystem mastery — from raw PHP to modern MVC frameworks like Symfony and Laravel, and enterprise e-commerce platforms like Magento and OpenCart.

I specialize in payment gateway integration — connecting web and mobile applications with providers like Stripe, PayPal, Paymob, and regional Middle Eastern payment processors. This has been the backbone of most projects I've delivered over the past 9 years.

Recently, I expanded into Flutter & Dart for cross-platform mobile development, allowing me to deliver complete solutions — from backend APIs to the mobile app — for clients who need a full product shipped. I'm also a strong Linux administrator, comfortable with server setup, deployment, and DevOps tasks.

I like working on Full Projects, and I'm also a good team player. Whether you need a senior engineer to lead a build, a freelancer to ship a feature, or a consultant to audit your payment flow — I'm ready.

Reading & Reviews

Continuous learning is part of the craft. Below is 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

by Dr. Flávio Gomes da Silva Lisboa
Reviewed November 2025

This book is for PHP developers, including beginners with basic PHP syntax knowledge, and intermediate developers seeking to adopt TDD and improve their application architecture. Familiarity with fundamental web development concepts will be beneficial for understanding the practical examples.

★★★★★

Symfony 6: The Fast Track

by Fabien Potencier
Reviewed March 2024

The definitive guide for any developer serious about mastering modern Symfony. As someone who has shipped Symfony applications for years, this book sharpened my understanding of the framework's internals — from the HTTP kernel to the new attribute-based routing. A must-read for backend engineers.

Symfony PHP Architecture
★★★★★

PHP 8 Objects, Patterns, and Practice

by Matt Zandstra
Reviewed February 2024

Remains the most thorough treatment of OOP and design patterns in PHP. The PHP 8 edition covers match expressions, named arguments, enums, and fibers. I reference this book weekly when architecting Laravel and Symfony services — an indispensable part of my professional library.

PHP 8 OOP Design Patterns
★★★★☆

Flutter in Action

by Eric Windmill
Reviewed January 2024

My gateway into Dart and Flutter development. Eric Windmill explains widgets, state management (Provider, BLoC, RxDart), and platform channels with clarity. While newer Flutter versions have evolved, the foundational concepts remain rock-solid. Highly recommended for PHP/backend developers transitioning to mobile.

Flutter Dart Mobile
★★★★★

Domain-Driven Design in PHP

by Carlos Buenosvinos
Reviewed December 2023

A practical, code-first approach to DDD in the PHP ecosystem. The authors demonstrate hexagonal architecture, CQRS, and event sourcing using real Symfony and Laravel examples. This book transformed how I structure complex e-commerce domains — particularly for multi-vendor marketplaces where bounded contexts matter.

DDD Symfony Architecture
★★★★★

Clean Code: A Handbook of Agile Software Craftsmanship

by Robert C. Martin
Reviewed November 2023

Uncle Bob's Clean Code is timeless. Although examples are in Java, the principles translate directly to PHP. I enforce these standards in every codebase I touch — from Laravel services to Magento modules. Every senior developer should re-read this annually.

★★★★☆

Magento 2 Development Beginners Guide

by Branko Ajzele
Reviewed September 2023

The most accessible entry point into Magento 2 module development. Covers dependency injection, plugins, events, and the UI component system. While some chapters need updating for Magento 2.4+, the architectural foundation remains invaluable for any developer building on Magento.
