Karim M.

Production-Ready MVP Developer | React, React Native, Next.js, Expo

I'm a software engineer with 10 years of experience building mobile and web applications using Typescript & React.js, React Native / Expo, Next.js, Supabase, Firebase, Node.js and Ruby on Rails. Over the years, I've worked on more than 30 professional projects across a variety of industries, gaining extensive experience building user-facing products from idea to production. While I have a strong technical foundation, I'm also highly product-focused. My goal is not simply to write code, but to build products that solve real problems, deliver value to users, and drive actual business revenue. I believe the best products are built iteratively. Rather than overengineering solutions, I focus on identifying the core features that create the most value, delivering them quickly, and establishing a solid foundation that can evolve as the product grows. When I'm not working on client projects, I'm building my own applications. That hands-on experience of designing, shipping, and iterating on products gives me a practical understanding of both the technical and product side of software development, which helps me work effectively with founders and entrepreneurs. I work mainly with Claude Code, which allows me to develop much faster and offer competitive pricing while still delivering high-quality work. Do not hesitate to reach out to discuss your project(s)! Best regards, Karim
