You will get Build an AI SaaS Product with Python Backend & APIs
Project details
What sets this project apart is a unique, cost-optimized approach to full-stack engineering that delivers production-ready SaaS platforms with near-zero monthly maintenance costs. Instead of stacking expensive, unnecessary cloud subscriptions, I design lean architectures that maximize free tiers and efficient microservices. I handle the complete application lifecycle: from crafting responsive, lightning-fast interfaces using pure frontend code to deploying containerized backend engines.

About Arnau
Product Builder | Full-Stack Developer | AI & Mobile Apps (Flutter)
Cocentaina, Spain - 3:17 am local time
I’m Arnau, a 22-year-old developer and designer who builds real products. I don't just write code; I launch businesses.
Everything I do for my clients, I have done for my own brands first. I am the creator of SMASH (a high-performance sports app built with Flutter & Firebase) and Louvr Labs (an AI-powered Meta Ads reporting SaaS).
How I can help your business grow:
• AI & SaaS Development: Custom web apps, OpenAI API integrations, and workflow automation.
• Mobile Development: Clean, scalable iOS/Android apps built in Flutter with RevenueCat integration.
• High-Converting UX/UI: Premium, minimalist design focused on actual ROAS and conversion rates.
If you are looking for a cheap pixel-pusher, I am not your guy. But if you want a strategic tech partner who builds with a quiet luxury aesthetic and cares about your bottom line—let's chat.
Steps for completing your project

Revisions may occur after the delivery date.
Technical Discovery & Architecture Mapping
We review your SaaS concept, map out the required user flows, and define the database schema. We also identify all necessary third-party endpoints (Meta Ads, Claude AI, Stripe) to ensure a solid system architecture before coding.
Responsive Frontend Development
I write clean, optimized HTML5, CSS3, and pure JavaScript to build the core responsive views of your Web App, including the Landing Page, User Onboarding, and the main Application Dashboard. Everything is hosted on Hostinger.
