About me
Background and how I work with teams and clients.
I am a full stack PHP Laravel developer based in Bangladesh, focused on scalable web applications, REST API development, and automation for retail and operations—especially POS software with inventory and sales workflows. I combine backend engineering with UI/UX design and frontend delivery using HTML, CSS, Bootstrap, and React, plus graphics in Adobe Illustrator. Whether you need a Laravel expert for an API, a product-minded developer for a POS rollout, or design-aware implementation, you can contact me or connect on LinkedIn.
Laravel projects & portfolio
Live demos and writing—evidence of API, POS, and teaching work.
API testing platform
Laravel-based REST API system and workflow for testing and integrating APIs—similar in spirit to tools like Postman, built for real API projects.
