Leveraged the 'Single Wire Protocol' (SWP) and the 'Host Controller Interface' (HCI) to manage I/O functioning• Extensively worked over 'Concurrency Management' for the InSE OS to parallelize multiple Logical I/O channels to function autonomously without affecting the flow of execution. The scope of I/O includes commands into the OS buffers via contactless interface (SWP) or contacted interface (HCI)• Involved in the complete versioning and modularization of the Embedded OS➜ 𝑰𝑵𝑵𝑶𝑽𝑨𝑻𝑰𝑶𝑵 𝑳𝑨𝑩𝑺𝑰𝒏𝒗𝒐𝒍𝒗𝒆𝒅 𝒊𝒏 𝒕𝒉𝒆 𝑰𝒏𝒏𝒐𝒗𝒂𝒕𝒊𝒐𝒏 𝒘𝒊𝒏𝒈 𝒂𝒔 𝒂 𝑺𝒐𝒇𝒕𝒘𝒂𝒓𝒆 𝑫𝒆𝒗𝒆𝒍𝒐𝒑𝒎𝒆𝒏𝒕 𝑬𝒏𝒈𝒊𝒏𝒆𝒆𝒓• Leveraged JavaScript to develop a 'Data Fetch software' responsible for extracting raw data from the Firebase server using various APIs into a consolidated Google Sheet (in a formatted way)• Introduced ease-of-access by developing a front-end web application using 'ReactJS' for a 'Biometric School Attendance' system which used the face biometrics to automatically manage student/faculty attendance at the server• Developed a front-end web application using 'ReactJS' for a 'Visitor Management System' leveraging face biometric authorization to expected visitors Show less

• Developed a SIM toolkit application (STK) for 2G and 3G SIM cards• Invested over 'Proactive Commands' which are commands discharged by the SIM to the terminal. Leveraged high-end simulators to examine proactive commands for SIM cards and later integrated a system by developing STK interfaces that would enable proactive commands from the SIM• Extensively worked on the ‘JavaCard’ Technology, ie, Java for Smart Cards. Earned hands-on experience over the in-depth memory… Show more • Developed a SIM toolkit application (STK) for 2G and 3G SIM cards• Invested over 'Proactive Commands' which are commands discharged by the SIM to the terminal.

Earned hands-on experience over the in-depth memory implementation of java objects, the JavaCard Virtual Machine (JCVM), and the JavaCard Runtime Environment (JCRE)• Extensively worked over the 'ByteCode Interpretor', the heart of the JCVM which is responsible for interpreting and converting each bytecode incoming from the application layer of an OS into system understandable machine instructions. Was involved with the substantial debugging and introduction of new bytecodes to the aforementioned Show less
