About

Nirjhar Roy is a highly skilled Software Engineer with 2.86 years of experience in the field. He holds a Master of Science degree in Computer Science and Engineering from the prestigious Indian Institute of Technology, Kanpur. Currently, he is working as an SDE 3 (Linux Kernel) at Fortanix Inc, a fast-growing startup. His work mostly focuses on EnclaveOS, which is a Linux-like library operating system. He implements missing Linux-like system calls and system-level nodes securely in EnclaveOS. Additionally, he adds support for various real-life customer demanding applications like Tensorflow Model Benchmarking, Openvino, Freeradius, etc. Nirjhar has extensive experience in research and development on secure demand paging schemes for enclave platforms like Keystone and Intel SGX. He has implemented most of the solutions in C and C++ and a bit of RISC-V/x86 assembly. He and his team used Python to develop simulators for tuning various page replacement and ORAM parameters. His research work has introduced new attacks and defenses on demand paging in enclave platforms. He has also developed new algorithms based on the Ring ORAM cryptographic primitive to enable performant and secure demand paging in the runtime for the Keystone enclave platform. Nirjhar is highly skilled in various technologies like Software Engineering, AI, Research Scientist, Tensorflow, Python, Docker, and testing. He has achieved a decent percentile of 99.65 (AIR 377) in GATE, a percentile of 97.6 in WBJEE and above 90% in his high school board examinations. Nirjhar is interested in working in areas of computer systems like operating systems, computer architecture, and/or computer security. In his previous role, Nirjhar worked as a Software Engineer 2 at Fortanix. He developed various features, new enhancements on EnclaveOS, implemented and fixed bugs securely in various Linux-like system calls and system-level nodes securely like /proc/cpuinfo in EnclaveOS, wrote unit tests for testing various Linux-like syscalls and system-level nodes implemented or bug fixed, added support for applications like Tensorflow and Openvino models benchmarking, and debugged applications inside the platform (EnclaveOS) using gdb. He also interacted with partners like Intel, attended weekly calls, and coordinated with them to enable various AI-related applications. Overall, Nirjhar is a highly skilled Software Engineer with a strong background in computer
