About Vaibhav Bhus
Engineering robust mobile software systems with an uncompromising focus on clean architecture, performance, and scalability.
I am a specialized Flutter & Mobile Engineer with 2+ years of production experience scaling SaaS mobile platforms to over 50,000+ active users.
Throughout my career at high-growth engineering teams like Knovator Technologies and Panara Studios, I have architected and deployed mission-critical healthcare (Omniva Telehealth) and recruitment (Artha Job Board) platforms end-to-end.
Mobile Architecture & Cross-Platform
Deep expertise in Flutter, Dart, platform channels, native iOS/Android background logic, and App Store / Play Store releases.
Clean Architecture & BLoC
Strict layer boundaries (Presentation, Domain, Data) ensuring testability, 35% higher modularity, and zero regression cycles.
120 FPS Optimization & Profiling
Startup latency reduction (-30%), memory leak profiling, Canvas rendering optimizations, and 99.9% crash-free session rates.
Automated CI/CD & OTA Updates
Codemagic pipelines, Husky Git hooks (-60% PR cycle), and Shorebird OTA for instant production hotfixes without store delays.
Flutter, Dart & Mobile Engineering Skills
Battle-tested mobile frameworks, clean architecture standards, and production tools engineered across 2+ years of high-scale SaaS.
Flutter
Custom RenderObjects, 120 FPS smooth rendering, cross-platform Android/iOS/Web.
Dart
Asynchronous streams, Isolates for background computation, strong type safety.
iOS & Android Native Bridges
Platform Channels, MethodChannel communication with Kotlin & Swift native SDKs.
Clean Architecture
Strict Presentation -> Domain -> Data layer separation with Dependency Inversion.
BLoC & Cubit State Machines
Event-driven reactive state, HydratedBloc caching, predictable state lifecycles.
Provider & Dependency Injection
Service locator pattern via get_it & injectable, decoupled unit-testable modules.
Stripe & Razorpay Payments
Multi-currency checkout, webhooks, automated subscription billing, 99.9% SLA.
Agora RTC Live Video
Ultra-low latency (24ms) HD video consultations, HIPAA-compliant telehealth stream.
FCM & APNs Push Engine
Background message triggers, payload routing, OneSignal integration, high open rates.
REST APIs (Dio Client)
Token refresh interceptors, automatic retries, gzip compression, caching layer.
Firebase Cloud Suite
Firestore real-time listeners, Cloud Functions, Auth, Storage, Security Rules.
Local DBs (Hive & SQLite)
