What I'm looking for

I want a remote-friendly team where I can build Flutter apps end-to-end—architecture, offline-first UX, backend integration, testing, and store publishing—while partnering with clients to ship reliable, performance-optimized products.

I’m a Senior Flutter Developer with 7+ years of experience building commercial Android and iOS applications used in production by 2,000+ businesses worldwide. As Founder of MRB-LAB, I lead the development of cross-platform mobile products, SaaS platforms, and client solutions with an architecture-first mindset.

I focus on Flutter architecture, scalable UI, backend integration, and offline-first applications—then take the work through publishing to Google Play and the App Store. I’ve built and managed a distributed team of developers and designers across multiple time zones, owning the full software development lifecycle from planning and UI/UX to deployment, maintenance, documentation, and customer support.

I’ve achieved Envato Elite Author status with 2,300+ commercial product sales and a 4.7/5 rating on Envato Market. From eCommerce and invoicing SaaS to news and education apps, I deliver production-ready products—often partnering with international businesses and agencies—and continuously optimize performance, testing, and reliability.
