I am a Curious Learner, Passionate for Kernel, Bootloader, Firmware, and any technology functioning closest to the hardware. But there is more about me.

Who am I?
● A person engaged in exploration, analysis, experimentation, and decisive action. In the initial six months of my bachelor's program in computer science, I systematically explored diverse domains. Through hands-on projects in AI/ML, Web Development, Android, Blockchain, and more, I concluded that my career aspirations align with the domain of Operating Systems and Kernel development.

● A developer keen on enhancing user experience, and prioritising customization without code modifications. One of my tasks at CERN was to configure U-Boot to load GRUB instead of the kernel, simplifying boot management for Sys-Admins across x86 and arm64 architectures with a unified GRUB configuration file.

● A person who will do one thing but will do it correctly. I refuse to compromise long-term success for short-term results. During my participation in the Linux Kernel Mentorship Program, I was assigned to work exclusively on legacy drivers. However, upon further analysis, I discovered that numerous generic drivers also utilized helper functions that required modification. Recognizing the importance of the task, I reported the findings and voluntarily undertook the additional responsibility. My overarching goal was to eliminate PCI helper functions and legacy Power Management framework support from PCI drivers, emphasizing a commitment to thorough and correct implementation.

● A proactive leader and team player who prioritizes the collective success of the team. I strongly reject the notion of evading responsibilities with the phrase 'That's not my job.' My technical proficiency is well-demonstrated through my hands-on experience; additionally, I have successfully managed social media profiles for my college's Open-Source society, including designing logos and maintaining documentation on its GitHub pages.

● A developer who prefers to spend time thinking out of the box rather than compromising on innovation, quality, and standards. We needed a controller-peripheral model in between RPi 3B+ and 2 RPi ZeroW boards for our Accinhibitor Project. Just a few hours before the competition, we found various bugs, and a fix was necessary. Since time was less and I didn't want to use brute force, I wrote a script to use 'ssh' for the communication between the boards.

I am bound to word-limit here but feel free to reach out. I enjoy meeting new people and exploring new possibilities.

1. Fellow - Software Engineer

   Sept 2021 - Present

   Organization: CERN
   
   

   As a Linux Kernel Developer at CERN, I led a significant project to create a tailored Linux-based operating system for the machines that control various instruments around the Large Hadron Collider (LHC). My role encompassed diverse tasks, highlighting proficiency in various tools and technologies; most significant of them are:

   Responsibilities:

   • Successfully ported 30+ drivers from CentOS-7 (based on linux-v3.10) to vanilla linux-v5.10.192-rt92. Standardized their build and install procedures using Makefile and GNU recommendations, cleaned up the code, and implemented a Gitlab-based CI/CD pipeline for all drivers to streamline testing and deployment.
   • Tested the ported drivers forPCI and VME devices, implemented feature requests like Hardware Monitoring (via Linux APIs), and resolved driver issues reported by users.
   • Customized Linux kernel configuration file for CERN machines, ensuring performance and size.
   • Utilized Packer (with HCL config) to achieve automated building of CentOS-9 Stream and Alma-9 based root filesystems, and Dracut to build a kernel independent initramfs. Conducted the preliminary OS testing by employing QEMU, initializing boot processes through network booting sequence.
   • Configured U-Boot to load GRUB for arm64 machines to unify the booting process for x86_64 and aarch64.
   • Devised an automated build system (Makefile and Gitlab CI/CD) for custom kernels. This includes downloading sources, verifying GPG signatures, patching custom changes, building, testing, and releasing kernels seamlessly.
   • Utilized Docker’s multi-stage feature to achieve complex but light weight images for CI/CD processes.
   • Contributed to drivers’ test suite (pytest based), ensuring comprehensive testing.

3. Linux Kernel Mentee

   May 2020 - August 2020

   Opportunity: Linux Kernel Mentorship Program with The Linux Foundation
   
   

   Responsibilities:

   • Removed the support of legacy power management framework from 210+ PCI drivers and upgraded them to generic.
   • Eradicated the dependency of drivers on PCI helper functions and shifted the entire load of power management on PCI Core.
   • Leveraged working-knowledge in Linux PCI Power-Management. Worked with tools like git, mutt, sparse, vim+cscope, etc.
