App Development

$22/hr Starting at $4K

End‑to‑end mobile product delivery using a single codebase (Flutter/React Native) to ship fast, stable apps for Android and iOS with clean UI, secure API integration, an admin panel for control, analytics/crash reporting, and app store submission assistance. Fixed scope, disciplined revisions, and transparent milestones protect timeline and budget.


What you get


UX/UI for 20–25 screens guided by brand styles, usability heuristics, and mobile best practices.

Cross‑platform build (Android + iOS) from one codebase for speed, consistency, and lower maintenance.

Secure API integration to your existing backend or third‑party services (auth, data, payments/ads).

Web‑based admin panel for core CRUD, roles/basic settings, and operational control.

App icon, splash screen, deep linking (if required), analytics (events), and crash reporting setup.

Optional push notifications (if included in scope) via Firebase or equivalent.

QA/UAT test builds, submission assistance for Google Play and Apple App Store, and source code handoff with setup notes.


Approach and process (30 days)

Week 1: Product walkthrough, feature freeze, design system and key screens, feedback loop (2 rounds + 1 polish).

Weeks 2–3: Feature development, API wiring, admin panel, basic analytics, crash reporting, and first test build.

Week 4: QA, fixes, UAT window, store assets prep, submission assistance, and code/doc handover.


Tech stack


Flutter or React Native for app; Node/Express/Laravel/Django for admin (based on fit and existing stack).

Firebase/Amplitude/GA4 for analytics; Sentry/Crashlytics for crash reporting.

Payment gateway or ad SDK integration (one), push via Firebase/APNs if in scope.

Quality and reliability

Strong typing and linting, modular architecture, environment‑based configs, and secure key handling.

Core performance checks: app startup, list scrolling, API latency handling, and offline guards.

Basic accessibility and mobile‑first layout testing across common devices.

Scope controls (to keep 30 days realistic)


Revisions:

 2 design rounds + 1 polish pass per screen group; functional changes handled via change‑requests.

APIs: Client provides documented, stable endpoints and credentials by Day 3; new endpoints or schema overhauls are out of scope.

Stores: Client owns Apple/Google developer accounts; policy‑driven rework beyond the initial checklist is billable.


Deliverables

Design files for final screens, production app builds, admin app deployed (or deployable), environment files, and README with setup instructions.

Submission support: metadata checklist, screenshots guidance, and first‑pass submission (resubmissions billed if policy‑related).

Source code and one live handover session.


Who this is for

Startups and SMBs needing a fast, clean MVP/MMP to validate and scale.

Teams with existing APIs/services seeking a polished mobile interface and lightweight admin.

Businesses migrating from web‑only to mobile presence without native‑native cost/timeline.
