1. What technologies do you use for Full-stack development?
I specialize in the modern JavaScript ecosystem. For the frontend, I use React and Next.js (for better SEO and performance). For the backend, I leverage the power of Node.js and Express.js to build scalable APIs. I also have extensive experience with jQuery for legacy system maintenance.

Security is my top priority. Drawing from my experience in runtime security and projects like NodeShield, I implement industry-standard security practices. This includes protecting against common vulnerabilities, managing dependencies through SBOM/CBOM analysis, ensuring secure API communications.

Yes, absolutely. I have significant experience developing robust management systems, featuring complex data visualization, user role management, and real-time updates.
4. What do you need from me to get started?
To provide the best results, I need a clear description of your project requirements, any existing design mockups (Figma/Adobe XD), and access to your hosting environment or repository if we are working on an existing codebase. If you use pnpm or specific Node.js environments, please let me know.
5. Do you provide support after the project is completed?
Yes, I offer a period of free support to ensure everything runs smoothly. Whether it's a minor bug fix in JavaScript or an environment configuration issue on your server, I am here to help you maintain a stable application.
