FAQ
Can you build a SaaS without real-time features?
Yes, I build both real-time and traditional SaaS platforms. Real-time features (like live chat or updates) are optional and can be added based on your needs.
Do you handle subscription payments and user management?
Yes, I can integrate Stripe, PayPal, or other payment gateways and build full user management systems with roles, permissions, and dashboards.
Can you work with our design/UI files?
Absolutely. I can implement designs from Figma, Adobe XD, or Sketch with pixel-perfect accuracy using React and Tailwind CSS.
What’s your experience with Next.js and Supabase?
I’ve built multiple production apps with Next.js (SSR, ISR) and Supabase (auth, real-time, database). Recent projects include ResearchCollab (real-time tool) and Huntsavino (SaaS platform).
Do you provide documentation and handover?
Yes, every project includes technical documentation, code comments, and a live handover session to ensure your team can manage the system.
Can you scale the app later as we grow?
Yes. I design the architecture with scalability in mind (database schema, API design, auth, roles) so we can add new features and users without rewrites.
What’s your experience with real-time features and WebSockets?
I’ve built production apps with live collaboration, presence, and activity feeds using Supabase real-time/WebSockets and similar technologies, including a research collaboration tool used across multiple teams.
