Building ethical, powerful software that respects users and creates meaningful impact. One developer, unlimited possibilities.
I'm Abu Naser, a passionate solo developer from Bangladesh focused on building clean, halal, and productive apps using Kotlin Multiplatform. I love making tools that solve real problems, especially in the language learning and productivity space.
✨ My apps work everywhere — Android, iOS, macOS, Windows, and Linux — with the same beautiful codebase.
Optimum-Tech is not just a brand — it's a mindset. Every app I build is crafted with clarity, minimalism, and Islamic principles in mind.
✨ No ads, no tracking, no shady stuff. Just powerful apps that respect users and devices.
I use Kotlin Multiplatform for shared code, Jetpack Compose for UI, and deploy across all platforms. Backend services are powered by Supabase, Ktor, and custom APIs.
✨ Designed to be fast, scalable, and completely open source.
To empower individuals with ethical, accessible, and effective tools — built with intention and care.
✨ Proving that one person can create beautiful, functional, and principled software for the world.
