Hamza A.

Senior Software Engineer building and maintaining production web applications: SaaS platforms, marketplaces, e-commerce systems, and API backends that handle real users, real payments, and real data every day.
Over 10 years, I've shipped full-stack products for long-term international clients, owning everything from database to UI to deployment. I take over existing codebases, stabilize them, and extend them without rewriting what already works.

Products I've built and maintain:
Hively: Multi-tenant HR SaaS I built end-to-end with Laravel, React, TypeScript, and Inertia. Attendance, leave, payroll workflows, and payment integrations serving live customers daily.
KeyLight: Payment and subscription platform on Symfony with full Stripe integration: checkout, webhooks, retry logic, and subscription lifecycle management.
Vayzone: Multi-vendor marketplace on Symfony and Sylius: custom storefronts, seller onboarding, order workflows, and third-party integrations.
Getin: Events platform with a Laravel REST API backend and Flutter mobile apps for iOS and Android.

Stack:
Backend: Symfony, Laravel, PHP 8, Node.js, REST APIs, Doctrine, Eloquent
Frontend: React, Next.js, Vue.js, TypeScript, Inertia.js
E-commerce: Sylius and Shopware 6, builds, customizations, plugins, and migrations
Mobile: Flutter and React Native when the product needs iOS and Android
AI: LLM and AI features integrated as clean backend services with defined inputs, limits, and failure handling
Database: PostgreSQL, MySQL, Redis
Infrastructure: Docker, AWS (EC2, S3, RDS, Lambda), CI/CD with GitHub Actions

How I work:
I ship in small, reviewable releases. Every change goes through version control with tests alongside production code. I communicate directly — no disappearing, no surprises.
When I take over a codebase, I audit first, flag risks, and propose a plan before writing a line of code. Most clients hire me for a fix or a feature and stay long-term because the code is clean, communication is clear, and nothing breaks after I ship.

Results:
Symfony REST API systems serving 2M+ requests per day
Reduced application response times by 60% through query optimization and caching
Migrated legacy PHP systems to modern frameworks without downtime
100% Job Success Score, Top Rated Plus, $500K+ earned on Upwork
Symfony Certified Developer (SensioLabs)

If you have a product that needs a developer who can take ownership and deliver, send me the project details, and I'll get back to you with a practical plan.
