What I'm looking for

I'm looking to build AI-powered, cloud-based mobile and full-stack products involving real-time systems, automation, and modern software tools.

I've built and maintained production-ready Flutter applications for Android and iOS at Advanced Apps Bangladesh, with a focus on scalability, performance, and user experience.

I develop complete mobile and web products using Flutter, Node.js, Express.js, MongoDB, and Firebase. My work includes secure authentication, REST APIs, chat, voice/video calls, real-time updates, Stripe and SSLCommerz payments, Google Maps, geolocation, notifications, and cloud integrations.

At Sebabajar Bangladesh, I translate product requirements into user-focused applications, from product and order workflows through deployment, maintenance, debugging, and continuous improvements.
