Profile
About me
I am MD Rabbi Hossain, an independent software developer and engineer based in Kaliganj, Jhenaidah, Khulna, Bangladesh. I work across the whole stack — from planning and design to deployment — building web applications, Android software, automated payment and verification systems, and other digital products.
My work is centred on FinTech automation, performance and privacy: I build tools that parse and verify real-time bKash, Nagad and Rocket payments, Android clients that run fast and respect user data, and web platforms that stay stable under real traffic. Over the last three years I have delivered more than 80 projects for 50+ clients.
I am the founder of RabbiHossainLTD, my independent software and digital services brand. The brand represents the work I do — rabbihossainltd.online is the official website, and more on the brand itself lives on the About page. Read on for my skills, the projects I have actually shipped, and where to find me online.
