Mobile App

A successful app depends on seamless integration between ‘UX/Planning’ and ‘API/Performance.’ To increase downloads, ratings, and retention simultaneously, the entire process—from technology to operations—must work in unison.

Delivering a consistent user experience across devices, OS versions, and screen resolutions

Handling app store policies and review schedules in parallel

Integrating payments, push notifications, real-time communication, and offline processing into a single architecture

Addressing technical constraints such as security, privacy, battery, and memory optimization

Eliminating communication gaps and accountability issues in fragmented outsourcing structures

Solutions

Agile Flutter front-end meets robust Spring Boot backend. Every stage—end to end—delivered seamlessly by one full-stack expert.

Execution flow: 90-min kickoff → 48-hour execution plan & estimate → project start within 7 days → 4-week MVP delivery

A single pipeline covering planning, UX/UI, Flutter app, Spring Boot API, admin portal, deployment, and operations

Fastlane + Gradle CI/CD pipeline with Firebase (Messaging, Crashlytics, A/B testing) for automation and observability

JWT/OAuth2-based Spring Security for authentication, authorization, audit logs, and rate limiting
