About this gig
Need a real web application built properly not a template, not a landing page?
I build production-ready web apps and SaaS products with React, Node.js and TypeScript, custom-coded from scratch, with AI built in where it earns its place
What I build:
- SaaS MVPs with authentication, billing and admin dashboards
- AI features inside your product: GPT and Claude chat, document processing, classification, summarisation, RAG over your own data
- Internal business apps and custom CRMs
- Client portals with role-based access
- Booking, membership and subscription platforms
- Custom APIs and integrations: Stripe, OpenAI, Anthropic, Twilio
- Stack: React, Next.js, Node.js, TypeScript, PostgreSQL, Tailwind
NOT for: landing pages, marketing sites, budgets under $800, timelines under 5 days.
You own all of it: source code, documentation, deployment access. Nothing locked to my accounts.
Metanow is an 8-person technical team: 7+ years, 1,700+ orders, 4.9 stars, Odoo and ERP work included.
Message me first with your use case, realistic budget and timeline. I'll tell you honestly if it's a fit, and if it isn't, I'll say so.
No AI-generated briefs. Serious inquiries only.

FAQ
Can you add AI features to my app?
Yes — GPT or Claude chat, document processing, classification, summarisation, or RAG over your own data. Available as a gig extra on any package. Tell me the use case and I'll say whether AI is the right tool or overkill.
Who pays for the AI usage?
You do, directly to OpenAI or Anthropic on your own account, so you keep control and your data stays yours. I size the likely monthly cost before we build anything.
How much does a web application actually cost?
Real web applications start at $800 for a foundation (auth, database, admin, one core feature) and go up from there based on scope. If your budget is under $800, this isn't the right gig — a landing page or template solution will serve you better.
Can you build my project in 3-5 days?
For a real web application, no. Foundation-tier projects need 7 days minimum. Full production SaaS work takes 14-30 days depending on scope. If you need something faster than that, it's either a landing page (different gig) or the timeline expectation isn't realistic.
What technologies do you build with?
React, Next.js, Node.js, TypeScript, PostgreSQL, and Tailwind CSS as the core stack. I use TypeScript across frontend and backend for type safety and long-term maintainability. For integrations I work with Stripe, OpenAI, Twilio, Supabase, and most modern APIs.
Do I own the code after delivery?
Yes, fully. You get the complete source code, documentation, and deployment access. Nothing is locked to my accounts. You can hand it to another developer, take it in-house, or extend it yourself.
I have a detailed spec document — can I just send that?
I'd rather have a short conversation first. AI-generated briefs often miss real requirements or include contradictory ones. A 15-minute back-and-forth over messages usually clarifies what you actually need better than a 30-page document.
What happens after the project is delivered?
You get the code, deployment, and documentation on delivery day. If you want ongoing support, I offer a monthly plan ($800/month) covering bug fixes, small changes, and technical support.
Can you integrate with (Stripe / OpenAI / my CRM / etc.)?
Almost certainly yes. If it has an API and documentation, I can integrate it. Common integrations included: Stripe (payments and subscriptions), OpenAI/Claude (AI features), Twilio (SMS/voice), SendGrid/Resend (email), Supabase/PostgreSQL (databases)
What if my requirements change during the project?
Small changes within scope — no problem, they're part of the revision rounds included in your package. Larger scope changes (new features, additional integrations, expanded user flows) will be handled through a custom offer with adjusted timeline and price.
