What GuiMah works with
02 — Work
A few things GuiMah has shipped. One of them is live on the App Store.
Language learning platform — designed, built, and launched on the Apple App Store.
Live shop for one-off outlet sneakers — catalog, checkout, and stock that leaves with the pair.
Visit live
Live law firm website for a São Paulo practice — built for real client enquiries, not a template.
Visit live
Live portfolio for a photographer & cinematographer — gallery, video flow, and a contact experience that works.
Visit live
Full-stack app for personalised meal planning, with image handling and user accounts.
Visit live03 — Services
Brief GuiMah once and get the whole stack — front to back, one team.
Web applications
Full products, not brochures. Real auth, real data, front-ends built to survive actual users.
Mobile products
React Native apps taken all the way through build, App Store review, and release.
AI & automation
Agents and LLM features wired into real products — with fallbacks, so they degrade gracefully.
Backend & APIs
APIs, schema design, caching, containerised deploys. Boring, documented, still readable in a year.
