Senior Backend Developer · PHP & Laravel
I'm Ahmed Elhefny. I've worked with PHP and Laravel for more than five years, over four of them professionally, building the server side of marketplaces, booking systems and SaaS platforms: payment flows, wallets, order lifecycles and the architecture that keeps them maintainable.
Five projects, each told as a problem, the decisions I made and what came out of them.
Two team projects worth a closer look.
Multi-vendor local delivery · 2024–2025
Backend developer in a small team
A delivery marketplace for supermarkets, pharmacies and produce shops with three apps (customer, store and driver) and an order that moves through 13 states. I set up the service layer and its generator, built the driver side of the order lifecycle, and built its most distinctive feature: ordering something that has no price yet.
What stood out: Negotiating a price inside the chat
Academic research services marketplace · 2025–2026
Lead backend developer
A live platform that connects researchers with consultants, technicians and institutions. It covers about thirteen request workflows (consultations, research, partial services, ethical approval, publishing, conferences and grants) plus a course platform, across five kinds of account.
What stood out: Many order types, one lifecycle
I built a workflow that turns a Figma file and a business analysis into small feature packs, then has AI agents implement each one under fixed architecture rules. I review every change and own the decisions.
Sole backend developer on most of what you see here, and a former backend team head who led up to 8 developers: reviewing code, mentoring developers and owning delivery.
