02How we work
Five steps. No surprises. Source on day one.
Discovery
Two-week paid sprint. We map product surface, edge cases, and the architecture before estimating.
Workshop · architecture spike
Architecture
Modular structure, state management, CI/CD, observability. Decisions written down.
BLoC · Riverpod · feature modules
Build
Two-week iterations. Internal builds via Codemagic on every merge. AI-assisted, code-reviewed.
Codemagic · GitHub Actions · Linear
Ship
Phased rollout, App Store and Play Store handled, error budgets in place before launch.
App Store · Play Store · feature flags
Maintain
Crash monitoring, performance budgets, dependency hygiene. We hand off when you're ready.
Sentry · PostHog · monthly health report
03Architecture Playbook
How we build mobile apps at Good Vibes Software.
We build Flutter apps that are meant to ship, grow, and survive — not just demos. Every project we take on follows the same set of engineering principles, refined over years of shipping production apps to real users.
One feature, one folder
Every part of your app — sign-up, payments, notifications — lives in its own self-contained module. New people joining your project can find what they need without spelunking. Features can be added, swapped, or removed without breaking what's around them.
Clear layers, no spaghetti
We separate the parts of your app that talk to the internet, the parts that hold business rules, and the parts that draw the screen. Sounds obvious — most apps don't do it. The payoff: when something needs to change (a new payment provider, a tweak to how data is stored), only one layer is touched. The rest stays still.
UI as a reusable kit
Buttons, screens, dialogs — we build them once and reuse them everywhere. On larger projects we extract the design system into its own package so multiple apps (or future white-label versions of yours) can share it. The result: visual consistency across every screen, faster brand updates, and lower long-term cost.
Three environments, zero surprises
Development, staging, production — every app we ship runs in all three. New features get tested with real data and real users before reaching production. Bugs get caught before they hit your customers.
State you can trust
We use BLoC, the most battle-tested state management pattern in the Flutter ecosystem, to make sure your app behaves predictably. Every screen knows exactly what to show, every error is logged automatically — so when something goes wrong, we know about it before your users complain.
Built for handover
Tests mirror the code. Naming follows strict rules. Linting runs on every change. If you ever need to bring the project in-house or onboard a new team, the codebase reads like a book, not a mystery novel.
Where AI fits
We use AI to accelerate the parts of engineering where speed pays off — boilerplate, refactors, test scaffolding, documentation. Not architecture. Not judgment. Not the decisions that determine whether your app still works in two years. Those stay with the engineers.
04Tech expertise
Flutter, end to end.
We're senior mobile engineers. We have shipped native iOS, native Android, and Flutter — and we choose Flutter today because it produces the best maintainability-per-dollar for most product teams.

We use Claude, Cursor, and Copilot inside our existing engineering process — not as a substitute for it. Generated code goes through review, type-checks, and the same test bar as human-written code. AI is leverage. It is not a shortcut around discipline.
