These were projects accomplished during my internship at Brain Machine AI through modern software engineering methods in solving industrially related challenges. The Hospital Management System aimed at facilitating record keeping for the patients, appointment scheduling, billing process, reporting function. tionalities. On the other hand, the POS system focused on the optimization of inventory management, sales tracking, HRM, and calculation of profit for the retail sector. Developmental life cycles that were developed include requirements analysis, system design, implementation, testing, and deployment, with the use of Django, PHP, SQL, and Git to efficiently collaborate and control versions. This paper brings forth the various challenges that came up during the development phases: handling complex data structures, user-friendly interfaces, and maintenance ing system reliability. Besides, the report presents professional, technical, and interpersonal growth achieved within the internship. Insights and experiences gained through working on these projects significantly added to my skill set, thereby improving my preparedness for various roles related to software engineering and systems development.29 pagesenBRAC University internship reports are protected by copyright.
