Hey! I'm Kanagaraj, known online as TamilXD — a self-taught developer from Tamil Nadu, India. I studied Electrical Engineering but fell in love with coding and never looked back.
Since then I've shipped Telegram bots handling real payments, built file streaming platforms, and developed mobile apps I'm genuinely proud of. Not portfolio projects — real stuff, running in production.
I learn fast, I care about the work, and I don't disappear after delivery. Let's build something worth your investment.

FAQ
What Flutter and cross-platform mobile app development services do you offer?
We offer Flutter & React Native app development for iOS and Android, covering custom mobile apps, MVP builds, UI/UX design, Firebase integration, REST API setup, push notifications, and full App Store & Google Play deployment.
Can you build for iOS only, Android only, or both platforms?
All three options are available. Flutter's cross-platform framework lets us deliver a high-performance iOS app, Android app, or both — from a single codebase — saving you time and development cost.
Can you redesign or revamp my existing Flutter or React Native app?
Absolutely. We handle Flutter app revamps, UI/UX redesigns, code refactoring, SDK migration, and performance optimization to bring your existing mobile app up to current standards.
Do you integrate Firebase, REST APIs, and third-party services?
Yes. We integrate Firebase, REST/GraphQL APIs, Stripe & PayPal payments, Google Maps, push notifications, and social login (Google, Facebook, Apple). Existing Firebase migrations are handled efficiently.
Will you publish my app to the App Store and Google Play Store?
Yes. We manage the full app deployment process — store listing setup, screenshots, compliance checks, and submission — for both the Apple App Store and Google Play Store
Will I receive the full source code of the app?
Yes. Upon project completion and full payment, you receive the complete, well-documented Flutter source code. Built on clean architecture, it's easy to maintain, scale, or hand off. Full ownership is yours.
What are your pricing, timeline, and payment terms?
Pricing and timelines vary by complexity and features. Simple apps take a few weeks; advanced apps may take months. We offer fixed-price or milestone-based payments. Message us for a free custom quote.
Do you offer post-launch maintenance and long-term support?
Yes. We provide ongoing bug fixes, OS compatibility updates, feature additions, and performance monitoring post-launch to keep your Flutter mobile app stable, secure, and competitive long-term.
