I build scalable apps
that people actually use.
Full-stack developer crafting mobile apps, SaaS platforms, and payment systems
that solve real problems for real businesses.
About Me
I'm Usman Sharif, a full-stack developer at Fiction Developers based in Pakistan, working with international clients to build products that matter.
Over the past 3+ years, I've shipped mobile apps to the App Store and Play Store, built SaaS platforms handling real revenue, and architected payment systems that process thousands of transactions. I don't just write code—I solve business problems.
My focus is on building scalable, maintainable systems. Whether it's a React Native app with complex state management, a Node.js backend handling millions of requests, or integrating payment gateways that need to work flawlessly—I deliver.
I work with startups and established companies who need someone who can move fast, think critically, and ship production-ready code.
