I help founders and product teams turn ideas into web and mobile apps that ship fast and scale cleanly. I bring the same engineering standards I used building at Careem, a leading ride-hailing platform in the Middle East, to every project I take on Upwork, where I hold a 100% job success score across 38 jobs. Most of my work is full-stack React and Next.js on the front end with Node.js on the back end, and I build for both web and mobile from a single Capacitor codebase. A good example is EVDC, an EV charging platform I built to run on web and mobile from one shared codebase, which keeps new features fast to ship and removes the cost of maintaining two separate apps. 🛠 What I build: Full-stack MVPs taken from idea to launched product for real market feedback Cross-platform web and mobile apps from a unified Capacitor codebase Scaling and refactoring existing products that have outgrown their first build Figma and design handoffs turned into responsive, production-ready interfaces Integrations with Stripe, AWS, Firebase, and third-party APIs ⚙️ How I ship: I write maintainable, well-documented code and treat production seriously. That means error monitoring with Sentry, CI/CD pipelines on GitLab, and fast delivery through AWS CloudFront, so what I hand over is stable, observable, and easy for your team to build on. 💻 Tech stack: Front-end: React, Next.js, TypeScript, Redux, Formik, Styled-Components, Tailwind CSS, Material UI Back-end: Node.js, Nest.js, Express.js, REST, and GraphQL APIs Mobile and cross-platform: Capacitor, React Native Databases: PostgreSQL, MongoDB, MySQL, Firebase Cloud and DevOps: AWS, AWS CloudFront, Docker, Vercel, GitLab CI/CD I also build on WordPress, WooCommerce, and Shopify when a project calls for it. If you are building something and want one developer who can own both the front end and the back end, send me a message with what you are working on. I will tell you honestly whether I am the right fit, what it will take, and what it will cost.
