You will get a SaaS MVP in Next.js and Node with Stripe billing, ready for users
Project details
A working SaaS product you can put in front of paying users - auth, database, core features, Stripe billing and deployment. Not a prototype you have to throw away.
Most MVPs get rebuilt within six months because they were built to demo rather than to run. I build the second version's foundations into the first: real schema design, proper auth, webhook-confirmed payments.
WHAT YOU GET
• React and Next.js front end with a Node.js API
• PostgreSQL or MongoDB with a schema that survives growth
• Authentication with JWT refresh-token rotation, or OAuth
• Stripe subscriptions with idempotent webhooks, so a customer who closes the tab after paying still gets access
• Deployment on Vercel or AWS
• Source code, schema and a written handover
AI FEATURES, BUILT PROPERLY
Where it fits, structured outputs bound to your schema and a draft-review-publish flow, so nothing a model generates reaches your users unapproved.
WHY IT MATTERS
The expensive part of an MVP is never the first version, it is the rewrite. Idempotent webhooks and a sane schema cost days now and save months later.
Technical Lead, 5+ years in production. Took key endpoints from about 4s to under 300ms.

About Shuja
AI Agents & RAG Systems | Full-Stack React, Next.js, Node.js
Islamabad, Pakistan - 10:20 am local time
I'm a Technical Lead and full-stack developer with 5+ years shipping production software. I lead a team of engineers by day and take on select client work — so you get someone who has actually run systems at scale, not just built demos.
━━━━━━━━━━━━━━━━━━━━
NOT TECHNICAL? START HERE.
You don't need to know what any of the words below mean. Here's what I actually do for you:
• Build the thing you're describing — a website, web app, internal tool or customer portal — and get it live.
• Add AI that's genuinely useful: a chatbot that answers from YOUR documents instead of making things up, or automation that does a repetitive job your team does by hand.
• Fix what's broken — slow pages, payments failing, an AI feature giving wrong answers, a developer who disappeared mid-project.
• Explain everything in plain English. No jargon, no talking down to you, no surprise invoices.
WHAT YOU CAN EXPECT
• A straight answer within 24 hours: what I'd do, what I'd build first, what it costs — before you commit a penny.
• Progress you can see every few days, not a three-week silence ending in a surprise.
• Nothing new breaks what's already working.
• Everything handed over documented and owned by you. Any developer can pick it up after me — you're never locked to me.
━━━━━━━━━━━━━━━━━━━━
TECHNICAL? HERE'S THE DETAIL.
AI & LLM ENGINEERING
RAG pipelines with LangChain and FAISS/Pinecone; chunking strategy and relevance thresholds tuned on real content. Multi-step agents with tool/function calling, self-correcting loops and evals. Structured JSON outputs bound to a schema so bad generations fail at the boundary. Prompt-level caching — cut OpenAI API costs ~30% on a production system. OpenAI, Anthropic Claude and Gemini APIs.
FULL-STACK
React, Next.js, TypeScript, Redux on the front end. Node.js, Express and NestJS APIs. PostgreSQL and MongoDB — schema design, compound indexing, aggregation pipelines (took key endpoints from ~4s to under 300ms). Redis caching and pub/sub for multi-instance deployments. Stripe subscriptions with idempotent webhook handling. JWT with refresh-token rotation, OAuth2.
INFRASTRUCTURE & QA
AWS (EC2, S3, RDS) with load balancing and auto-scaling. Docker, GitHub Actions, CI/CD. Selenium and Puppeteer end-to-end suites that run in CI. Web scraping and structured data extraction at scale.
HOW I WORK
Branch per task, PR with a written description of what changed and how I verified it — repro steps, not "works on my machine." I use Claude Code and Cursor daily, but I read every diff before it ships. The tooling speeds up typing, not judgement.
━━━━━━━━━━━━━━━━━━━━
Send me your repo, a Figma link, or just a paragraph on what's broken. Within 24 hours I'll come back with how I'd approach it, what I'd build first, and what I think it costs — before you've committed to anything. If the plan is useful, we start. If it isn't, you've lost nothing and you keep the plan.
