Building production web applications with a focus on multi-tenant architecture, e-commerce infrastructure, and maintainable software systems.
Bangladesh · Building software since 2018
I build and maintain software products that solve real business problems, from multi-tenant SaaS platforms and point-of-sale systems to e-commerce infrastructure and administrative dashboards.
My work spans frontend and backend development, API design, database architecture, authentication, and production operations.
I care about clear architectural boundaries, reusable components, data integrity, security, and code that remains maintainable as products evolve.
