About Me

Passionate Flutter Developer & Problem Solver

With 4+ years of experience in mobile development, I build fast, polished apps for Android and iOS using Flutter and FlutterFlow, backed by Firebase. My work spans AI-powered tools, ride-hailing platforms, fintech, health apps and business websites.

I've worked with SoftRadix Technologies and Arific Business Solutions, shipping apps for clients in Venezuela, Brazil, South Korea, the US and India. I also build Wear OS and Apple Watch companion apps and native SwiftUI apps.

Before moving into development, I spent over seven years in export operations at Jindal Polybutton, running export data on ERP software and automating reports in Excel, which is where my interest in software began. That background helps me understand how businesses actually work, so I build apps around real workflows.

I care about clean, maintainable code, smooth user experiences, and apps that are ready for Google Play and the App Store from day one.

Frequently Asked Questions

Can't find your answer? Message me and I'll reply personally.

How much does it cost to build an app?

It depends on the features, platforms and design. After a short chat about your idea, I send a clear, itemised estimate and timeline before any work starts.

How long does it take?

Timelines depend on scope. A focused MVP is much quicker than a full platform with admin panels, payments or real-time features. You get a milestone plan up front, so you always know what is next.

Can you build for both Android and iOS?

Yes. With Flutter or FlutterFlow, one codebase runs natively on Android and iOS. I also build native SwiftUI apps and Wear OS and Apple Watch companion apps.

Will you publish the app to Google Play and the App Store?

Yes. I prepare the builds and store listings, handle submission and review feedback, and can publish under your own developer accounts.

Can you work on my existing app?

Yes. I can fix bugs, add features, improve performance or take over an existing Flutter, FlutterFlow or native app.

Do I own the source code?

Yes. When the project is complete, you receive the full source code, and your app, store listings and backend stay in your own accounts.

What do you need from me to get started?

Just your idea. A short description, any designs or reference apps you like, and your timeline are enough for me to send an estimate.
