Full Description
Have a SaaS idea but need it built fast? I build minimum viable products (MVPs) that real users can sign up for, use, and pay for — in 10 to 21 days, not 6 months.
An MVP isn't a mockup. It's a working product with real authentication, a real database, a real payment system, and a real dashboard users can log into. It's what you need to validate your idea, land your first paying customers, and raise funding before investing in a full build.
What every SaaS MVP includes:
• User authentication — signup, login, password reset, email verification
• One core feature — the main thing your product does, working end-to-end
• User dashboard — where customers see their data and use the product
• Admin panel — see users, subscriptions, activity, and support issues
• Stripe subscriptions — monthly or yearly recurring billing with webhooks
• Multi-tenant architecture — each customer's data isolated and secure
• Transactional emails — welcome, receipts, password resets, notifications
• Deployed live with custom domain + SSL — ready for real users
• Full source code + documentation
• 30-60 day post-launch support
What I can build for you:
• Booking and reservation SaaS — salons, clinics, restaurants
• Project management tools — task boards, team collaboration
• CRM platforms — lead tracking, sales pipeline, deal management
• Internal business tools — inventory, invoicing, staff management
• AI-powered SaaS — chatbots, document Q&A, content generators
• Subscription content platforms — courses, memberships, newsletters
• Multi-tenant dashboards — SaaS for other businesses to use
Full stack I work with:
Frontend — React 19 · Next.js 15 · TypeScript · Tailwind CSS · Framer Motion
Backend — Node.js · Express · Laravel 11 · Python (FastAPI) · REST APIs
Database — PostgreSQL · MongoDB · MySQL · Supabase · Redis
Auth — NextAuth · Clerk · Supabase Auth · JWT · OAuth · 2FA
Payments — Stripe · PayPal · Paystack · Flutterwave · Stripe Subscriptions
Email — Resend · SendGrid · Mailgun
Deployment — Vercel · Render · AWS · Docker · Cloudflare
How I work:
1. You share your idea — features, users, and revenue model
2. I confirm scope, timeline, and price with a clear milestone plan
3. I build a working staging version — you get a live URL to test
4. You review, request changes, and I refine
5. Final delivery — deployed production app + source code + documentation
Why clients choose me:
I've built SaaS platforms, marketplaces, and multi-tenant apps for clients in the US, UK, UAE, and Africa. My restaurant SaaS platform (Zaragoza) uses the same stack as a typical MVP — Next.js + MongoDB + JWT + admin dashboard + Stripe integration. Every project ships with a live staging preview before final payment.
Important: you provide your own Stripe account, API keys, and third-party accounts. I'll guide you through setup and integration — but billing stays under your control.
Send me your idea and I'll tell you exactly what's possible, what it costs, and how long it takes.

Frequently Asked Questions
Every package includes a post-launch support window (14-60 days per tier) for bug fixes, small adjustments, and priority support. After that, a monthly maintenance retainer covers ongoing development, security updates, and feature additions.
Yes. Standard and Premium tiers can include AI features — chatbots, document Q&A (RAG), content generation, intelligent search, classification, and AI agents. I use OpenAI GPT-4o, Claude, and Gemini depending on the use case.
Yes, before work starts. Once I begin and share a staging preview, refunds aren't available — but you only pay final after reviewing the working product on a live URL. If the preview doesn't match scope, no payment is due.
You own everything — 100%. Full source code, database access, Stripe account, hosting account, and deployment credentials stay under your name. No platform lock-in, no recurring fees to me.
Yes — Premium tier includes multi-tenant architecture with row-level data isolation. Each customer company gets their own isolated workspace inside the same app. Standard tier covers single-user accounts and teams within one organization.
Absolutely — most clients ship the MVP, get real user feedback, then extend it in a second phase. I offer follow-up project rates and monthly retainers for ongoing development. Nothing is wasted — the code is designed to scale.
No. If you have a Figma file, I'll match it. If you don't, I'll design a clean, modern UI based on your product type. For technical decisions (stack, architecture, database), I'll recommend based on your requirements — you just approve.
Stripe is the default for subscription billing — it handles recurring charges, webhooks, invoicing, failed payment retries, and VAT/sales tax. Paystack and Flutterwave are available for African markets. You own the Stripe account — billing always stays under your control.
Basic: 10 days. Standard: 15 days. Premium: 21 days. Timelines assume you respond to reviews within 24-48 hours. Rush delivery possible on Standard and Premium — message me before ordering.
A SaaS MVP (Minimum Viable Product) is the smallest working version of your software product — real user accounts, one core feature, real payments, and a live URL. It's what you need to launch, get your first paying customers, and validate the idea before investing in a full build.
Communication happens via Zinn Hub messages (primary), with optional add-ons:
• Weekly Loom video updates showing progress on the working build
• Live video calls on request (Google Meet) for milestone reviews
• Email updates for anything urgent
• Slack/WhatsApp available as paid add-ons if you prefer real-time chat
You'll get a clear weekly rhythm — no silence gaps. Every milestone gets a Loom walkthrough so you can see exactly what's been built without waiting for a formal review
Yes. Many SaaS founders are building in stealth mode — I understand that.
Send your NDA before the order starts and I'll sign it. I also never share client project details, code, or plans publicly. Your product stays confidential. For added peace of mind, I can share portfolio work privately on a call (with permission) instead of publicly listing it.
The MVP scope is locked in writing before I start building. If you need features outside that scope mid-project, I'll quote them as a separate add-on — with a clear price and timeline — before building anything. Nothing gets added silently. Nothing gets billed without your approval.
For small tweaks within the agreed scope (a button change, a text update, a colour adjustment), those are covered under your revision rounds and cost nothing extra.
No — hosting and third-party service fees are not included in the project price. You pay those directly:
• Hosting (Vercel / Render / AWS): typically $0–$30/month depending on traffic
• Database (PostgreSQL / MongoDB Atlas / Supabase): free tier available for most MVPs, ~$20–$50/month at scale
• Stripe: 2.9% + $0.30 per transaction
• Email (Resend / SendGrid): free tier covers most MVPs, ~$20/month at scale
• Domain name: ~$10–15/year
I'll recommend the cheapest setup that fits your expected usage before I build. You own all accounts — I never mark up hosting costs. I do help set everything up as part of the build.
My public SaaS work includes the Zaragoza Restaurant platform (live at zaragoza-restaurant-nine.vercel.app) — a full-stack SaaS with auth, admin dashboard, and API integration. I also have private client MVPs that can be demoed on a call (with client permission).
If you want to see how I work before committing, I can build a small proof-of-concept based on your idea — a single working feature — for a fixed micro-fee. That de-risks the decision for you without a large upfront commitment.
Every milestone is delivered as a working, deployed version — so you always have a functional product, not a half-built codebase. If anything happens to me, your project is fully in your hands:
• Full source code lives in YOUR GitHub repository from day one (not mine)
• Weekly Loom walkthroughs document what was built and how it works
• Written documentation covers setup, deployment, and architecture
• Your Stripe account, hosting account, and domain are all under your name
You're never dependent on me to keep the product running. Worst case, any competent developer can pick up where I left off using the documentation.
Yes. Standard and Premium tiers include full internationalisation support:
• Multi-language UI (English, Arabic, French, Spanish, German, and any language you need)
• RTL (right-to-left) support for Arabic, Hebrew, and Urdu
• Locale-based routing (e.g., /en/, /fr/, /ar/)
• Multi-currency pricing display
• Locale-aware dates, numbers, and formats
Built with next-intl or react-i18next. Language files are structured so you or your team can add new languages without touching the code. Perfect for SaaS targeting non-English markets — including MENA, EU, and Latin America.
Yes. Before you commit to the full project price, I offer a free 30-minute discovery call or a written scoping questionnaire. We'll cover: the core feature you want built, the users and roles involved, your pricing model, timeline constraints, and any design references you have.
After that, I send back a scope document — features included, features excluded, milestone plan, and fixed price. You review it, request changes if needed, and only then do you place the order. No surprises, no rushed commitments.
