FAQ
What tech stack do you use?
Frontend: React, Next.js, TypeScript, TailwindCSS. Backend: Node.js or FastAPI with PostgreSQL or MongoDB. I recommend the best stack for your project after we discuss your needs.
Can you build a dashboard with charts and analytics?
Yes — it is one of my specialties. I use Recharts or Chart.js for interactive visualizations. I have built agricultural dashboards, energy analytics platforms, and fleet management dashboards with real-time data.
Do you handle deployment?
Yes. Premium package includes Docker setup and full cloud deployment to Vercel, AWS, or Azure. Standard package includes deployment instructions and guidance.
Can you add authentication and user roles?
Yes — Standard and Premium packages include JWT authentication. I can also set up OAuth (Google, GitHub login), role-based access control, and multi-tenant architectures for the Premium tier.
Will the app be mobile-responsive?
Every app I build is mobile-first responsive. I use TailwindCSS or Material-UI for clean, adaptive layouts that work on all screen sizes — phones, tablets, and desktops.
Can you work with my existing project or design?
Yes. I can build from a Figma design, extend an existing React/Next.js codebase, or add backend features to your current frontend. Just share what you have and I'll review it before starting.
