Build or Extend a Next.js Web Application with AI Features
I build production-ready Next.js applications with AI capabilities built in—from scratch or integrated into your existing codebase.
What I deliver:
• Full-stack Next.js (App Router, TypeScript, Tailwind CSS)
• AI features: chat assistant, semantic search, recommendations, content generation
• Auth (Auth.js), database (MongoDB, Postgres/Prisma), REST APIs
• Payment integration (PayPal, Stripe)
• Real-time features (Socket.io)
• Deployed on GCP, Railway, or Vercel
Production reference: mequedo.app — AI booking platform with natural language concierge, built entirely by me and currently live.
Packages:
Starter · $800—Core app + 1 AI feature, auth, deployed (7 days)
Growth · $1,500—Full app + 3 AI features, payments, real-time, 30-day support (10–14 days)
Custom · $2,500+ — Complex platforms — let's scope together

About Carlos
Full-Stack AI Engineer | LangChain RAG Pipelines Next.js N8N Autom
Barquisimeto, Venezuela - 7:26 pm local time
My most recent project, Mequedo, is a live booking platform where an AI concierge recommends accommodations based on natural language input. Built end-to-end: Next.js + TypeScript, Django/DRF, LangChain RAG pipeline powered by Llama 3 via NVIDIA API.
I also served as Lead Software Engineer at One Community Global (US nonprofit), contributing 63 commits to a production MERN dashboard used across the organization.
What I build:
• Conversational AI agents with custom knowledge bases (LangChain, RAG, vector DBs)
• AI-powered web apps (Next.js, TypeScript, React, Python/Django)
• Business automation workflows (N8N, Make)
• Real-time features (Socket) and payment integrations (PayPal)
• REST APIs with Express.js and Django REST Framework
Stack: TypeScript · Node.js · Python · Next.js · React · Django · LangChain · RAG · Llama 3 · NVIDIA API · N8N · Make · Socket · MongoDB · GCP
English C1 — clear async communication, no repeated back-and-forth.
If you need an AI feature shipped to production, a RAG chatbot trained on your own data, or automation that saves your team hours every week — I deliver on time.
Steps for completing your project
After purchasing the project, send requirements so Carlos can start the project.
Delivery time starts when Carlos receives requirements from you.
Carlos works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & architecture
I review your intake answers, codebase (if existing), and design files. I define the full tech stack, database schema, API structure, and AI feature design. You receive a written scope document to confirm before any code is written; no surprises...
Project setup & scaffolding
I initialize the Next.js project (or branch your existing repo), connect the database, configure authentication with Auth.js, set up environment variables, and wire the deployment pipeline. Everything is connected before features are built.
