Who is behind it
Hi, I'm Leoni. From code to client.
I work on four fronts. I build custom websites and systems, with code I write myself and real attention to performance. I create my own digital products, like PageTester PRO. I am the development team for agencies that need their Figma design live, white-label. And I look after the traffic: campaign landing pages, A/B tests and SEO. I take on clients in Brazil and abroad, and you always deal with me directly.
