iOS and Android

Mobile app development

Apps for companies that need to leave the idea stage, unblock a product or put an operation in the customer's pocket. The focus is a usable, stable product that can evolve.

The problem this service solves

An app usually stalls when the scope mixes validation with an entire platform, or when production code no longer matches real use. I define what must exist now, build the core journeys and leave integrations, release and maintenance in order. I am based in Porto Alegre, Rio Grande do Sul, and work remotely with companies across Brazil.

Benefits

One codebase, two stores

iOS and Android from a shared codebase when that reduces time and cost without sacrificing the experience.

Scope that fits the moment

MVP, evolution or team support, with deliveries the business can use and evaluate.

Real integrations

Authentication, APIs, notifications, payments and the services a product needs beyond a prototype.

Release support

Preparation for the App Store and Google Play, including the build flow and the care a real release needs.

FAQ

Can we launch an MVP first?

Yes. The first version covers what validates the operation or the value proposition, without forcing the rest of the roadmap to ship at once.

Can you take over an existing app?

Yes. I start by reading the code, dependencies, release process and risks. Deliveries then follow a safe order across fixes, structure and features.

Does the app need a site or admin panel too?

When the business needs it, the app can ship with a website, an admin panel or a web system. That is defined in the scope, not added as a surprise.
