About me
👋 Hi, I’m Krishna Kumar, a Bachelor of Technology graduate from Dr. M.G.R. Educational and Research Institute, Maduravoyal. I’m passionate about 🌐 cybersecurity, 🖧 networking, 🧩 virtualization, and ⚙️ automation technologies. I love exploring Linux systems like 🐧 Ubuntu, 🧠 Kali Linux, and 💾 TrueNAS, as well as virtualization tools such as Proxmox for building and managing home-lab environments.
🐳 With Docker, LocalStack, and YAML-based automation, I simulate cloud platforms like AWS (S3, EC2, Lambda, DynamoDB, SQS) in local environments. I’ve created 🧰 batch scripts that automate ngrok setup, container deployment, and file transfers between devices via browser-based systems that function like FTP servers.
💡 I also developed an OPC (Open Platform Communication) server for hardware communication and enjoy experimenting with Jenkins, Kubernetes, and containerized environments. I believe strongly in 🛡️ ethical cybersecurity practices, 🏠 self-hosting, and the power of open-source learning.
🚀 My goal is to build a career in Cybersecurity, Cloud Infrastructure, or DevOps, where I can combine my curiosity, problem-solving mindset, and hands-on experience to design secure, automated, and efficient systems.
