You will get Build a Custom Web App or SaaS MVP Powered by AI


Project details
Your idea deployed in days, not months. Real product. Your domain. Ready for real users.
Most MVPs die in the "I'll build it next month" loop. I break that loop. You bring the idea — I ship the product.
Built with: Next.js, TypeScript, Tailwind, Supabase, Stripe.
AI features where they actually move the needle — not bolted on for show.
This works for:
Founders validating an idea this week
Non-technical operators who need a clear quote and timeline
Pre-seed teams shipping before the next milestone
Indie hackers who want polish on a lean budget
Why me:
I come from B2B sales before I came to code. That means I don't just build what you ask for — I build what will convert your users. Every screen is a sales screen and every flow is a funnel.
What you walk away with:
Working product on your domain. Clean code on GitHub, fully yours. Responsive on desktop, tablet, and mobile. Ready to onboard real users on day one.
After you order:
Scope doc within the hour. Daily progress updates. Delivered on the date I commit to — not the date I hope for.
Pick your tier and let's ship. If you're unsure on scope, start with the smallest one — we can always expand.

WHY CLIENTS HIRE ME:
- 6 years in B2B sales before this — I build AI that actually moves revenue, not demos
- Bilingual English/Spanish — fast timezone overlap with US, EU, and LATAM clients
- Business-first thinking — I flag issues before they get expensive and push back when something isn't the right call
- Daily updates so you're never guessing. Fast iteration, real feedback loops.

Steps for completing your project

Delivery time starts when Nicolas receives requirements from you.
Nicolas works on your project following the steps below.

Discovery Call & Technical Scope
We jump on a 30-min call to lock in features, tech stack, and success metrics. You get a written scope doc with timeline, milestones, and exactly what ships — no vague deliverables.
Design Preview & Build Sprint
I send design mockups within 48 hours for approval. Once you sign off, I build with Claude Code + modern stack (Next.js, Supabase, Stripe) and share daily progress so you see it come together live.
