About

👋 Hi, I’m Arpit Khetan — a Software Development Engineer at Cisco working on Data Security Systems ( Data Loss Prevention, Endpoint Data Loss Prevention, Data Security Posture Management, etc. ) with a focus on systems design and production-grade backend engineering. 💻 I specialize in backend and systems engineering, with hands-on experience building production-grade features across C++, Rust, and Java — from architecture design to deployment. 🚀 At Cisco, I’ve been driving end-to-end development of features, working on: • Endpoint DLP with deep OS/system-level integrations • DSPM systems for data discovery, classification, and risk analysis across various platforms • Legacy DLP platforms, delivering production features in fast-paced environments ⚙️ I enjoy working on low-level systems, performance optimization, and cross-language architectures (C++ ,Rust), especially where design meets real-world constraints. 🏆 Previously, I led DTU’s INFERNO Mars Rover Team and contributed as a Placement Coordinator, managing large-scale campus recruitment efforts. 🌱 I’m always looking to learn, build, and collaborate on impactful systems in security, backend, and distributed architectures
