Core Technologies
What We Build
Engineering across the full Android stack.
Native Android Development
Java-based apps built on clean architecture — from single-activity systems to modular, offline-first designs.
PHP Backend Development
REST APIs on PHP 8+, engineered for real shared-hosting constraints without cutting corners on security.
Firebase Integration
Authentication, Crashlytics, and FCM wired in correctly from day one — not bolted on after launch.
SQLite Offline Support
Offline-first caching layers that keep apps usable on unreliable connections, a real constraint for our market.
App Performance Optimization
Profiling, memory audits, and rendering fixes that turn a functional app into a fast one.
Google Play Publishing
Data Safety forms, manifest hardening, privacy policy generation, and ad-compliance review handled end to end.
Flagship Product
Englo — English, learned online & offline-first.
Englo is Radixivity's flagship English learning app for Bangladeshi students — 11 learning modules spanning vocabulary, grammar, spoken English, reading, writing, and verb conjugation, built to stay usable on patchy connections, with Firebase-backed sync and daily-streak progress tracking once you're back online.
