The Solution: A personalized, automated platform that handles the “heavy lifting” of expat bureaucracy—from canceling utilities to handling residency paperwork.
Status: Evolving from a niche automation tool into a comprehensive, AI-assisted expat assistant.
The Problem: Media buyers spend hours manual-reporting and analyzing ad performance.
The Solution: A micro-SaaS that connects to the Meta Ads API to rank creative performance and send automated “Monday Reports” via email.

I am a creator who lives at the intersection of Design, Code, and Business. My experience ranges from handling logistics at Deutsche Post in Germany to building AI-driven software. I don’t just build features; I build solutions that solve real-world friction.”
Let’s Build Something Great
Automated Workflows & Micro-SaaS
I build lightweight web applications, AI-powered tools, and API integrations that eliminate manual work. Whether it’s connecting Meta Ads data to automated reports or building custom AI grading tools, I turn complex workflows into simple, scalable software.
iOS & Android Apps (Flutter & Firebase)
From the first Figma wireframe to the final App Store launch. I design and develop cross-platform mobile apps with clean architectures, real-time database integrations, and optimized in-app subscription flows (RevenueCat).
Figma to Code — Built for Results
I don’t just design pretty interfaces; I design for conversions. I craft premium dashboards, landing pages, and digital storefronts that guide users toward action. My background in physical packaging design ensures your brand looks cohesive both on-screen and in hand.
Shopify, Marketplaces & Performance Marketing
Technical setup is nothing without a growth engine. I combine advanced Shopify customization, Etsy SEO/print-on-demand operations, and high-ROAS Meta Ads campaigns to scale brands across European and US markets.
Builder first. Freelancer second.
I’m Arnau, a 22-year-old product builder from Spain. I started building e-commerce businesses at 19 while working full-time in logistics at Deutsche Post in Germany.
Every service I offer—from AI automation and mobile apps to premium Shopify ecosystems—is something I’ve battle-tested on my own brands first. Live products like SMASH and Louvr Labs are my proof of work: fully operational, self-funded, and built entirely by me.
I build with a quiet luxury, minimalist aesthetic that runs through every pixel. I don’t just ship deliverables; I drive results.
