FAQ
What do you need from me to get started?
Simply share your project brief, wireframes/designs (Figma or sketch, if available), and a list of required core features or API integrations. If you only have a rough concept, we can refine the scope together.
Do you provide the full source code and ownership?
Yes, every package includes 100% complete, well-documented source code ownership with clear repository structure upon project completion.
Can you help design the UI/UX in Figma before coding?
Absolutely. You can select the Figma UI/UX Gig Extra, and I will design interactive, editable wireframes and components to finalize the layout before writing production code.
What technologies do you use for backend, database, and auth?
I build scalable backends using Node.js/Express or Next.js API routes, paired with PostgreSQL or MongoDB databases, and implement secure auth via Clerk, NextAuth, or JWT/OAuth 2.0.
Will the web application be mobile-responsive and SEO-optimized?
Yes, all applications are built mobile-first with Tailwind CSS, fully responsive across devices, and optimized for fast load times and Core Web Vitals.
Do you assist with hosting setup and cloud deployment?
Yes, I handle end-to-end production deployment on platforms like Vercel, AWS, or Render, including custom domain DNS configurations and environment security setup.
