Rabishtra engineers high-performance, 60 FPS native Android applications in Android Studio using Kotlin, Java, XML, and Jetpack Compose. Backed by scalable cloud infrastructure across Firebase, AWS, Cloudflare, and Supabase.
Rabishtra is a specialized software engineering studio founded to deliver senior-level native Android apps and cloud architectures without agency bureaucracy. You communicate directly with the lead architect who writes, tests, and ships your product.
We adhere strictly to modern Android architecture principles: MVVM / MVI patterns, Clean Architecture with isolated UseCases, and offline-first database synchronization. Whether building greenfield Kotlin Compose apps or refactoring legacy Java and XML codebases, every screen is optimized for battery efficiency, memory stability, and instant cold starts.
A great mobile app requires an bulletproof backend. We configure, connect, and scale Firebase, AWS, Cloudflare, and Supabase tailored to your exact budget and throughput needs.
End-to-end engineering from wireframing to Google Play Store production approval, telemetry monitoring, and ongoing version upgrades.
Complete product delivery built inside Android Studio using Kotlin and Jetpack Compose (or Java & XML). Responsive across all form factors including Android phones, tablets, foldables, and Chromebooks.
Architecting resilient backends using Firebase, AWS, Cloudflare, or Supabase with real-time sync, webhooks, and REST/GraphQL APIs.
Gradual, safe refactoring of existing Java and XML codebases into modern Kotlin and Jetpack Compose with zero downtime and backwards compatibility.
Eliminating memory leaks, jank, slow cold starts, and ANRs using Android Studio Profiler, LeakCanary, and Firebase Crashlytics.
Navigating Google's strict 2026 developer requirements, target SDK bumps, Data Safety declarations, and closed testing tracks for smooth approval.
Carefully chosen, battle-tested technologies that ensure your application is fast, secure, and ready to scale to millions of users.
A predictable, transparent development roadmap from initial specification to Play Store release.
We clarify functional requirements, define the database schema, select the optimal backend (Firebase vs. AWS vs. Supabase), and sign a mutual NDA to protect your IP.
Setting up Android Studio with Clean Architecture, designing Material 3 screens in Jetpack Compose or XML, and creating clickable prototypes for early review.
Iterative coding sprints with weekly test builds delivered to your device. Continuous integration, real-time cloud sync, and unit testing across every module.
Assisting with Google Play Console closed testing tracks, Data Safety compliance, production rollout, and providing a 60-day bug-fix warranty.
High-performance mobile applications engineered with scalable patterns, offline-first synchronization, and sleek Material 3 design systems.
Enterprise fleet monitoring and telemetry dashboard with offline sync, low-latency Jetpack Flow streams, and real-time alerts for field operators.
Next-generation digital card wallet featuring biometric authentication (Fingerprint & Face Unlock), AES-256 hardware keystore encryption, and real-time spend analytics.
Real-time community app featuring sub-second chat messaging, live audio room streaming via ExoPlayer, and push notifications via Firebase Cloud Messaging.
Why global founders choose a specialized studio engineer over bloated digital agencies.
| Engagement Factor | Traditional Agency | Rabishtra Studio |
|---|---|---|
| Point of Contact | Account managers & non-technical coordinators | Direct communication with your lead engineer |
| Engineering Talent | Junior developers learning on your budget | 100% senior native Android & cloud craftsmanship |
| Agile Velocity | Multi-layered approvals and change order delays | Weekly builds delivered directly to your device |
| Intellectual Property | Complex licensing or vendor lock-in | 100% IP & full Git repository ownership transfer |
| Post-Launch Warranty | Expensive monthly retainer required immediately | Included 60-day zero-cost bug-fix warranty |
Clear, transparent answers about project engagements, code ownership, and technical workflows.
Yes, completely. Upon final milestone payment, full ownership of all custom source code, Git repositories, design assets, and architectural documents is transferred directly to your organization. We also sign mutual Non-Disclosure Agreements (NDAs) prior to starting any project.
It depends on your product goals:
We analyze your requirements during Discovery to recommend the most cost-efficient choice.
We assist you end-to-end through Google Play Console setup: packaging Android App Bundles (.aab),
configuring ProGuard/R8 obfuscation, preparing Data Safety privacy disclosures, and navigating the 14-day 20-tester
closed testing verification required by Google for new accounts.
Yes. We have extensive experience maintaining legacy Java and XML codebases as well as incrementally migrating them to modern Kotlin and Jetpack Compose without requiring a risky, expensive full rewrite.
We operate with an agile, asynchronous-first workflow. You receive weekly video progress demos, live test builds via Firebase App Distribution, and daily Slack/WhatsApp communications with working overlap across US (EST/PST), European (GMT/CET), and Asian timezones.
Every production application includes a 60-day zero-cost bug-fix warranty. If any bugs or crashes occur in the delivered code during this period, they are resolved at zero cost. Ongoing maintenance retainers are also available for library upgrades and OS updates.
