Production Architecture

3D System Topology & Hybrid Engine

Our bespoke Flutter architecture separates structural presentation nodes from database synchronization pipes. By caching requests local-first on SQLite/Hive, Nasit Brothers eliminates network round-trip delays and ensures smooth scrolling interfaces at a solid 120 FPS.

🚀 GPU-Accelerated UI Compilation

We compile Dart directly to ARM machine binaries utilizing Impeller, completely avoiding JavaScript bridges or slow WebViews. This results in smooth micro-animations and zero frame drops.

🔧 Code Health & Bug Mitigation

We fix sluggish app bugs by isolates offloading (running heavy JSON parsing in secondary Dart isolates to keep the UI main thread free) and caching network queries to avoid redundant API load.

☁️ Dual Hybrid Backend

We combine Firebase Firestore (for instant messaging and push notification alerts) with Supabase PostgreSQL (for row-level secure relational data, invoice billing, and user login pipelines).

📁

Database Integrations

We write structured, isolated data interfaces targeting specific read/write speeds, scale requirements, and database sync frequencies.

Firebase Firestore (NoSQL Real-time)

Perfect for messaging features, order chat rooms, and background analytics syncs. Uses offline data persistence handlers natively.

Supabase PostgreSQL (Relational Transaction Core)

Houses relational schemas, RLS (Row-Level Security) policies, custom transactional triggers, and handles financial booking ledgers.

Local SQLite Cache (Offline-First Cache)

Saves network responses on device via local key-value lists and SQLite databases. Prevents screen freezes when offline.

⚙️

Core Third-Party Services

Seamless connection to third-party SDKs and payment portals to supply complex features without breaking interfaces.

Google Maps Geolocation SDK

Enables background coordinate tracking, route compilation, restaurant area geofencing, and delivery bike pins.

Stripe / Razorpay Payments

Secure checkout pathways using custom card overlays, tokenized gateway security, and automatic webhook status returns.

Firebase Push Notifications

Delivers notification payloads to clients instantly using FCM. Supports background notifications and custom sound channels.

Our workflow

How We Build & Deploy

A rigorous, systematic engineering cycle structured to eliminate bugs, maximize performance, and speed up launch times.

01

Figma Prototyping

We prototype every view inside viewport canvases, planning micro-interactions and transitions before writing a single line of Dart.

02

Clean Code Architecture

Structuring folders into clear data, domain, and UI layers. Utilizing BLoC or Riverpod to isolate widget rebuilds and keep memory leaks at zero.

03

Hybrid Backend Sync

Configuring PostgreSQL triggers in Supabase and real-time document listeners in Firebase. Merging them into a local-first SQLite cache.

04

120 FPS Performance Audits

Running analyzer scripts, profiling GPU thread metrics, eliminating main-thread blockages, and deploying through Fastlane pipelines.

Zero Bugs Guarantee

Quality Assurance Checklist

✓

120 FPS Framerate Profile

We audit scroll behaviors and widget animations under heavy loads, ensuring Impeller renders frames in under 8ms with zero stutter.

✓

Offline Caching Resilience

We verify SQLite database reads and background write syncing when cellular network or Wi-Fi connectivity is disconnected.

✓

Multi-Device Layout Audits

Testing across screen size scales, from compact Android models up to large iPads and tablets, ensuring responsive text flows.

✓

Security RLS Rules Testing

We validate Row-Level Security parameters on every table database in Supabase, keeping customer invoices isolated and secure.

Common Questions

App Development FAQs

Do you sign non-disclosure agreements (NDAs)? +

Yes, absolutely. Before we discuss project flows, figma layouts, or database architecture blueprints, we sign a standard NDA to protect all intellectual properties.

How does the hybrid Firebase + Supabase backend work? +

We use Supabase PostgreSQL as the secure relational storage core (for handling customer transactions, profiles, billing ledger accounts). In parallel, Firebase handles instant push notifications (FCM) and fast client analytics events. This provides high reliability while keeping cloud costs minimal.

Will the app work offline? +

Yes. We implement local cache logic (SQLite / Hive). Queries are resolved instantly from device storage first, and background sync engines upload write changes to cloud tables as soon as internet connection is restored.

What is the average timeline for custom builds? +

Depending on complexity (number of custom pages, dynamic services, API syncs), standard template deployments range from 3 to 6 weeks, while large scale bespoke designs take 8 to 12 weeks.
