About Me

Gaurab Roy profile photo
Flutter Dev

I'm Gaurab Roy, a Flutter Developer from Kolkata, India — building the mobile apps that startups, enterprises, and entrepreneurs rely on.

With 3+ years of hands-on experience, I've shipped cross-platform Flutter apps from concept to the Play Store and App Store. I work across the full app lifecycle — requirements gathering, UI/UX, architecture, integration, testing, and deployment.

I care about clean architecture, performance, and real business impact. Every app I build is crafted to be fast, maintainable, and designed to convert users into loyal customers.

I've worked with startups and established companies alike, regularly interacting with clients directly to turn their vision into a polished, store-ready product.

Why Work With Me

Full App Lifecycle

From requirements gathering to Play Store / App Store deployment — I own the complete development cycle, so nothing falls through the cracks.

Startup Mindset

I've built apps from zero to launch for startups. I understand speed, pivots, lean budgets, and the importance of shipping product that works.

Direct Client Communication

I've regularly gathered requirements, managed feedback, and delivered tailored solutions — no chain-of-telephone miscommunication.

Performance-First

GPU-aware animations, lazy loading, efficient state management — I optimise for frame rate and responsiveness so users never notice the seams.

Clean Architecture

BLoC, Riverpod, proper layering — my codebases are maintainable and easy to hand off. Future developers will thank you for choosing me.

Cross-Platform ROI

One codebase, two stores. Flutter lets me deliver both Android & iOS simultaneously — halving your time to market and development cost.

Get In Touch

Whether you have a startup idea, an enterprise app to build, or just want to discuss Flutter — I'd love to hear from you.
