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.

Successful trading bots aren't defined by how many strategies they support they're defined by execution speed, reliability, and profitability under real market conditions. Whether it's arbitrage, MEV, sniping, or high-frequency trading, milliseconds matter. A slow transaction, poor routing logic, or unreliable infrastructure can mean missed opportunities and lost revenue. Building automated trading systems that execute with speed, precision, and resilience is what I specialize in. I'm a blockchain and trading bot developer with 6+ years of experience building automated crypto trading solutions across Solana, Ethereum, BNB Chain, Base, and other EVM-compatible networks. I help startups, trading firms, and individual traders develop high-performance bots that monitor markets in real time, execute complex strategies, and operate reliably in fast-moving blockchain environments. I've contributed to trading infrastructure handling high transaction volumes, low-latency execution, real-time blockchain monitoring, and automated decision-making across decentralized exchanges and on-chain ecosystems. Some of the trading systems I've worked on : MEV Trading Infrastructure – Developed high-speed MEV bots capable of monitoring mempools, identifying profitable opportunities, and executing frontrun, backrun, and sandwich strategies with optimized transaction routing and priority fee management. Multi-DEX Arbitrage Platform – Built an automated arbitrage engine that continuously scans liquidity across multiple decentralized exchanges, detects price discrepancies, simulates profitability after gas and fees, and executes trades with minimal latency. Token Sniper & Launch Bot – Engineered token sniping bots that monitor new liquidity events, whitelist launches, and token deployments, executing buy and sell strategies with configurable risk controls, wallet management, and automated profit-taking. My technical stack includes Rust, Solidity, Anchor Framework, Solana Web3.js, Web3.py, Ethers.js, Node.js, Python, TypeScript, Go, WebSockets, RPC optimization, Flashbots, Jito, MEV infrastructure, DEX integrations, Uniswap, Raydium, Orca, Jupiter, PancakeSwap, Ethereum, Solana, BNB Chain, Base, REST APIs, PostgreSQL, Redis, Docker, Kubernetes, AWS, GCP, and real-time blockchain data processing. Every trading system I build is designed for speed, stability, and continuous operation. That means optimized execution paths, efficient RPC usage, robust error handling, risk management, detailed logging, and extensive testing before deployment. I believe transparent communication is just as important as technical execution, so you'll always know the status of your project and the reasoning behind key implementation decisions. If you're building an arbitrage bot, MEV strategy, sniper bot, copy trading platform, market-making system, Telegram trading bot, or any automated crypto trading solution, I'd be happy to discuss your requirements. Share your strategy or idea, and I'll provide an honest assessment of the best technical approach and how we can turn it into a reliable, production-ready trading system.
