Need someone who can manage your Linux infrastructure and actually knows what's happening below the application layer? I'm Shivam, a Linux systems engineer and DevOps specialist with 5+ years of experience, and a contributor to the Linux kernel mainline. I build, secure, and debug Linux servers and cloud infrastructure with the kind of low-level systems knowledge most DevOps engineers don't have. 𝐇𝐎𝐖 𝐈 𝐂𝐀𝐍 𝐇𝐄𝐋𝐏 𝐘𝐎𝐔 🐧 𝐋𝐢𝐧𝐮𝐱 𝐒𝐲𝐬𝐭𝐞𝐦 𝐀𝐝𝐦𝐢𝐧𝐢𝐬𝐭𝐫𝐚𝐭𝐢𝐨𝐧 Provision, configure, and harden Linux servers (Ubuntu, Debian, RHEL/CentOS). Comfortable with systemd, networking, user/permission management, backups, and security hardening for production systems. 🧩 𝐋𝐢𝐧𝐮𝐱 𝐊𝐞𝐫𝐧𝐞𝐥 𝐃𝐞𝐛𝐮𝐠𝐠𝐢𝐧𝐠 & 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 𝐓𝐮𝐧𝐢𝐧𝐠 As an actual contributor to the Linux kernel mainline, I can dig into problems most admins can't, kernel-level memory issues, driver conflicts, and performance bottlenecks below the application layer, not just symptom-level fixes. ⚙️ 𝐃𝐞𝐯𝐎𝐩𝐬 & 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐚𝐬 𝐂𝐨𝐝𝐞 CI/CD pipelines, Docker containerization, and Terraform-managed infrastructure. I build fault-tolerant, repeatable systems instead of fragile ones held together with manual SSH sessions. 🌐 𝐂𝐥𝐨𝐮𝐝𝐟𝐥𝐚𝐫𝐞 𝐒𝐞𝐭𝐮𝐩 & 𝐎𝐩𝐭𝐢𝐦𝐢𝐳𝐚𝐭𝐢𝐨𝐧 DNS configuration, CDN tuning, WAF/security rules, and Cloudflare Workers for edge logic, get your site fast, secure, and resilient. ☁️ 𝐂𝐥𝐨𝐮𝐝 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 (𝐀𝐖𝐒) EC2, Lambda, S3, and CloudWatch setups designed for reliability and cost efficiency, backed by my AWS Certified AI Practitioner credential. 🏆 𝐋𝐈𝐍𝐔𝐗 𝐊𝐄𝐑𝐍𝐄𝐋 𝐌𝐀𝐈𝐍𝐋𝐈𝐍𝐄 𝐂𝐎𝐍𝐓𝐑𝐈𝐁𝐔𝐓𝐎𝐑 This is the part most Linux freelancers can't say: I've had patches merged into the actual Linux kernel. My work has included fixing how `vrealloc()` releases physical memory pages when shrinking allocations (it previously only updated bookkeeping), adding memory-shrinking support to a Rust kernel data structure, and a related optimization in the Rust binder driver, plus hardware-specific display/backlight driver fixes. The work was reviewed and signed off by core Linux maintainers, including Andrew Morton, the longtime maintainer of the kernel's memory-management subsystem. In practical terms: if your issue is below what a typical sysadmin can diagnose, an odd kernel panic, a memory leak invisible to application logs, a misbehaving driver, I can read the kernel source and actually fix it. 🌟 𝐖𝐇𝐀𝐓 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐒𝐀𝐘 🌟 ❝ Working with Shivam was a fantastic experience. His expertise in performance-oriented languages like Rust and C++ was a game-changer for our project. He delivered a highly efficient and meticulously optimized solution, demonstrating a rare talent for deep, logical problem-solving at the systems level. What impressed me most was his ability to connect this low-level expertise with high-level strategic thinking. He doesn't just understand the algorithms; he has the foundation to make them run incredibly fast. Highly recommend for any demanding technical role. ❞ - Client ❝ great to work with ❞ - Adam C. ❝ Shivam was amazing. This was my second time using him for a project and I was extremely happy.
