About Sam

I am a Senior Full-Stack Developer with strong expertise in Angular, React, Node.js, and .NET, specializing in building scalable web applications, secure APIs, and data-driven systems. I help companies design and deliver reliable software solutions that are cleanly architected, performance-focused, and ready for real-world use.

On the frontend, I develop modern, responsive user interfaces using Angular, React, Next.js, HTML5, and TailwindCSS. I focus on component-driven architecture, clean state management, and user experiences that scale across devices and browsers.

On the backend, I build robust services using Node.js, ExpressJS, and the .NET Framework, with a strong emphasis on RESTful API design, authentication systems, and business logic implementation. I work extensively with MySQL and SQL-based systems, ensuring efficient queries, data integrity, and long-term maintainability.

I have hands-on experience developing real-time applications using WebSockets, implementing secure user authentication, and integrating payment systems such as Stripe for subscription-based and transactional platforms. My background allows me to work comfortably across both JavaScript and C# ecosystems, making me effective in mixed-technology and enterprise environments.

What I help clients with:
  • Full-stack web application development (Angular, React, Node.js, .NET)
  • RESTful API design and backend architecture
  • Secure authentication and authorization systems
  • SQL and MySQL database design and optimization
  • Real-time features using WebSockets
  • Stripe payment and subscription integrations
  • Clean, maintainable, production-ready code
I work best with startups, SaaS companies, and enterprise teams that need a developer who understands both technical depth and business requirements.

If you’re looking for a reliable full-stack developer who can own features end-to-end and deliver high-quality results, I’m ready to help.
