01About me
Eleven years of building web applications end to end — from the interface people use to the APIs, databases and cloud infrastructure behind it.
I'm Hamza, a Senior Full Stack Engineer with more than eleven years of professional experience. I currently work as a Senior Software Engineer at Seamless Distribution Systems AB in Sweden, leading frontend development of enterprise products with React, Next.js, TypeScript and a micro-frontend architecture.
Before that I spent six years at the same company as a Software Engineer, delivering client projects end to end: PHP backends on Laravel, CodeIgniter and other frameworks, JavaScript frontends, AWS infrastructure, and integrations with payment, messaging and email providers.
Alongside that work I've built more than 150 websites and web applications for clients across 30+ industries and 15+ countries — business platforms, e-commerce stores, WordPress builds and SaaS tools. I'm as comfortable designing a database schema as refining a UI detail, I work well in agile teams, and I use AI-assisted tools like Claude, GPT and GitHub Copilot to move faster without cutting corners.
