At Brainstation-23 PLC, I led the end-to-end delivery of Ez floor Pro, a production-grade, multi-tenant SaaS CRM for window tinting businesses. I designed its five-layer backend architecture and implemented tenant data isolation, OAuth2 authentication, and access controls.
For Ez floor Pro, I developed CRM modules for contacts, projects, proposals, invoices, sales pipeline, inventory, and teams. I also integrated Stripe and PayPal for subscription billing and automated invoicing.
I built a Vue 3 single-page application with dashboards, scheduling, PDF generation, and workflow automation, and contributed to Docker-based deployment pipelines. I implemented an AI-Driven Development Lifecycle to enhance development automation and delivery efficiency.
At MirInfo System LTD, I worked on Grameenphone Web and related services, including Flexiplan. I helped deliver a payment and data-pack purchase system with an automated retry mechanism to handle failed activations while preserving transaction integrity.
