You will get Full-stack AI SaaS MVP built with Next.js in 4-6 weeks
Project details
I build full-stack AI SaaS products from idea to live, paying users in 4 to 6 weeks. If you have a concept and need a working product instead of a prototype, this is for you.
Your MVP runs on Next.js, with a Supabase or PostgreSQL backend, Stripe subscription billing, secure authentication, and AI features powered by OpenAI or Claude. Everything is structured so you can launch, charge customers, and scale later without rebuilding.
What you get:
A complete full-stack web app: frontend, backend, database, and deployment
User authentication, accounts, and role-based access
Stripe subscription billing and customer management
AI features built into the core: chat, content generation, RAG, or agents
Admin dashboard to manage users, data, and usage
Clean, documented code that you fully own
I work in clear weekly milestones, so you see progress every week instead of waiting until the end. You receive a working product, the full source code, and documentation your team can build on.
Tell me about your idea and I will map out the scope, stack, and timeline before we start.

About Saifullah
AI Full Stack Developer | AI Agents, AI SaaS, RAG, n8n, Claude, MCP
Woodbridge, United States - 12:05 am local time
Hi, I'm Saif — a full-stack AI developer who builds production-ready AI applications, SaaS products & integrations for founders, agencies & growing businesses.
Over the past 4 years, I've delivered 50+ AI products & full-stack systems for clients across healthcare, SaaS, e-commerce, real estate & agency operations. I work across the entire stack: backend APIs, frontend interfaces, database design, AI workflow integration, and deployment.
My background combines strong software engineering fundamentals with deep, hands-on AI expertise — which is why clients keep coming back when they need to scale or expand their systems.
My focus is on building things that ship and hold up under real users — AI-powered SaaS platforms, intelligent web & mobile applications, RAG-based knowledge systems, AI agents, voice bots & automation workflows that quietly do the work of a small team.
⭐ What I Can Help You Build:
✔️ AI-powered SaaS products — MVP development, full-stack architecture, multi-tenant systems, admin dashboards
✔️ Custom AI agents & multi-agent systems - LangChain, LangGraph, CrewAI, AutoGen
✔️ RAG pipelines & AI knowledge bases with vector databases like Pinecone, Weaviate, Chroma, Qdrant & pgvector
✔️ Full-stack web applications with AI features built in from the architecture up
✔️ Mobile applications with AI capabilities using React Native & Expo
✔️ E-commerce platforms with AI-powered search, recommendations & customer support
✔️ Voice AI agents built on Vapi, Retell AI, ElevenLabs, Twilio & Deepgram
✔️ Workflow automation with n8n, Make , Zapier & custom Python services
✔️ MCP (Model Context Protocol) servers & integrations — connecting Claude & other LLMs to your tools & data
✔️ OpenAI, Anthropic Claude & Gemini API integrations into existing applications
✔️ Custom REST and GraphQL APIs, plus third-party integrations (CRM, CMS, payment gateways, communication tools)
✔️ AI-powered chatbots, customer support systems, and internal copilots
⭐ Tech Stack I Work With:
✔️ Languages & Frameworks: Python, JavaScript, TypeScript, FastAPI, Node.js, Express, NestJS, Next js, React, React Native, Expo
✔️ AI & LLM Tools: LangChain, LangGraph, LlamaIndex, CrewAI, AutoGen, OpenAI API, Anthropic Claude API, Google Gemini, Hugging Face, DSPy
✔️ Vector & Search: Pinecone, Weaviate, Chroma, Qdrant, pgvector, Elasticsearch
✔️ Databases: PostgreSQL, Supabase, MongoDB, Redis, MySQL, Prisma, Drizzle
✔️ Voice & Telephony: Vapi, Retell AI, ElevenLabs, Twilio, Deepgram, Whisper
✔️ Automation: n8n, Make, Zapier, Pipedream, custom Python workers
✔️ Cloud & DevOps: AWS, Vercel, Railway, Render, Docker, GitHub Actions, Cloudflare
✔️ Payments & Auth: Stripe, Paddle, Clerk, Auth0, NextAuth, Supabase Auth
✔️ AI Dev Tools: Claude Code, Cursor, GitHub Copilot, v0, Replit Agent
⭐ Industries I've Worked With:
Healthcare & medical practices, SaaS startups, digital agencies, e-commerce and D2C brands, real estate, fintech, legal services, education & training organizations & B2B service businesses.
⭐ Why Clients Choose Me:
I take ownership of every project, which means I don't just write the code you ask for — I help you think through the architecture, flag potential issues early and make sure what we build can actually scale once real users show up.
I communicate clearly throughout the project with daily or weekly updates, Loom walkthroughs for milestones & direct answers when you have questions. I deliver on agreed timelines and provide proper documentation so your team can maintain and extend the system after we wrap.
I also work AI-native — Claude Code, Cursor, and modern AI dev tools are part of how I ship, which means I move 3–4x faster than traditional development cycles while maintaining production-grade quality. For teams adopting these tools themselves, I also offer Claude Code coaching & consulting.
⭐ How I Work:
We start with a quick discovery call to understand your goals, constraints, and timeline.
I propose a clear scope with weekly milestones and fixed deliverables — no vague open-ended work.
You get daily or weekly progress updates with demo links, Looms, and screenshots so you always know where things stand.
Every project ships with documentation, architecture notes, runbooks, and a support window after delivery.
⭐ Best Fit Clients:
Founders building their first AI product. Agencies that need reliable white-label AI delivery. Operators looking to automate manual workflows. SaaS teams adding AI features to existing products. Companies needing custom MCP integrations connecting LLMs to their internal tools.
Whether you're early-stage & exploring what's possible, or you have a clear scope and need someone to execute, I'd love to hear about what you're working on.
