Veelgestelde vragen
Do you build both frontend and backend for a full stack web app?
Yes. As a full stack MERN and Next.js developer, I handle everything — React/Next.js frontend, Node.js/Express or FastAPI backend, and MongoDB or PostgreSQL database — so you get one complete, production-ready app
Can you fix or improve an existing Next.js or React project?
Absolutely. I regularly take over existing MERN stack and Next.js codebases to fix bugs, optimize performance, and add new features without breaking what's already working.
Can you add AI features like chatbots or automation to my web app?
Yes, I can integrate AI features like chatbots, smart search, or automation into your full-stack app using OpenAI or Claude API. For advanced multi-agent systems or complex AI workflows, check out my dedicated AI agent gig for a deeper build.
How fast can you deliver a full stack web app?
Most full stack projects (React/Next.js frontend + Node.js backend) are delivered in 3-7 days depending on scope. I'll give you an exact timeline after reviewing your requirements.
Can you integrate OpenAI or Claude API?
Absolutely. I specialize in AI integrations including OpenAI, Claude, and LangChain-based agents.
Do you sign NDAs?
Yes, I'm happy to sign an NDA before starting. Just send it over and I'll get it sorted quickly.
Do you build with Next.js or just React?
Yes, I use Next.js as my primary framework for most projects — including App Router, server-side rendering, and API routes on top of the MERN stack (MongoDB, Express, Node.js).
