At Information Automation & Technology, I lead backend module development for SMS Gateway and Building Management System platforms. I implemented reseller hierarchies and granular RBAC, and worked on a relational database with 120+ normalized MySQL tables.
I also engineered a Shadow Admin mode and Sender ID allocation logic, and integrated third-party REST APIs, webhooks, and notification pipelines. Earlier, as a Software Developer Intern, I developed secure CRUD features in CodeIgniter and MySQL and worked on production fixes and SQL performance.
