About Rabishtra

Dedicated Native Android Studio, Handcrafted for Global Products

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.

Enterprise Android Engineering, Built Right

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.

Cloud Backend Mastery

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.

How We Work

The 4-Step Engineering Process

A predictable, transparent development roadmap from initial specification to Play Store release.

01

1. Discovery & Spec

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.

02

2. Architecture & UI

Setting up Android Studio with Clean Architecture, designing Material 3 screens in Jetpack Compose or XML, and creating clickable prototypes for early review.

03

3. Sprint Development

Iterative coding sprints with weekly test builds delivered to your device. Continuous integration, real-time cloud sync, and unit testing across every module.

04

4. Release & Warranty

Assisting with Google Play Console closed testing tracks, Data Safety compliance, production rollout, and providing a 60-day bug-fix warranty.

FAQ

Frequently Asked Questions

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:

  • Firebase: Ideal for rapid MVP launches, real-time sync, and seamless push notifications (FCM).
  • Supabase: Perfect if you need relational PostgreSQL with complex queries, Row-Level Security, and zero vendor lock-in.
  • AWS (Amazon Web Services): Best for high-volume enterprise compute, custom serverless Lambdas, and S3 media storage.
  • Cloudflare: Great for edge caching, ultra-fast Workers, and enterprise-grade DDoS/SSL protection.

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.
