About Marwan
Full-Stack Software Engineer • .NET • React • Scalable Web & Enterprise Solutions
I’m a results-driven full-stack software engineer with solid experience building robust, scalable applications using .NET, .NET Core, React and modern web technologies. I design and implement high-quality software that aligns with both technical requirements and business goals — from backend APIs and microservices to intuitive front-end interfaces.
I’ve delivered complex solutions in enterprise environments, contributing end-to-end development expertise through the full software lifecycle: architecture, coding, testing, deployment, and iteration. I collaborate effectively with product owners, cross-functional teams, and stakeholders to deliver value-driven outcomes.
Core strengths include:
Backend development with C#, .NET / .NET Core
Front-end engineering with React
RESTful API design, integration & optimization
Clean, maintainable code and best engineering practices
Agile teamwork and transparent communication
I’m open to freelance projects where I can help build, improve or scale your software products — whether you need feature delivery, architecture support, or performance enhancements.
