I build websites and web apps in Next.js, from a marketing site to something with logins, a database, and real functionality behind it. Hosted on Vercel, built to load fast and not fall apart the first time real users touch it. Where it helps I add AI on top: a chatbot, smarter search, an internal tool that used to be a spreadsheet. A 5-page site and a full web app are different jobs, so scope and price depend on what you actually need. Send me your brief and I'll tell you straight what it takes.
