FAQ
What tech stack do you use?
I specialize in the MERN stack—MongoDB, Express.js, React and Node.js. This unified JavaScript ecosystem speeds up development and allows for seamless collaboration
Can you build both the front‑end and back‑end?
Yes. I design responsive React/Next.js interfaces and write robust Node.js back‑end services. Using MongoDB or Supabase (PostgreSQL), I deliver fully functional full‑stack solutions.
Do you use Supabase or Firebase?
I usually recommend Supabase because it provides root access to a PostgreSQL database, strong security and real‑time features. However, I’m comfortable working with Firebase or other databases if they better suit your project.
How do you handle authentication and security?
I implement secure authentication flows using Supabase Auth and row‑level security, or JWT/OAuth where appropriate HTTPS, environment variables and role‑based access control are standard in every project.
Will you deploy my project?
Absolutely. I deploy to Vercel or alternatives. I understand that Vercel’s usage‑based pricing and serverless limits can be tricky, so I configure deployments to balance cost, performance and scalability.
Do you integrate third‑party APIs?
Yes. I connect payment gateways, social logins, analytics services and any REST/GraphQL API your application requires. API integration is part of every Standard and Premium package.
How do you ensure scalability?
I design architectures with modular code, environment‑based configurations and cloud‑native patterns. Supabase and MongoDB scale horizontally, while Node.js and React allow for optimized performance under high traffic.
Can you build AI‑enabled features?
Yes. Supabase’s pgvector support enables vector searches and recommendation systems. I integrate AI APIs or custom models to deliver intelligent user experiences.
