Hi, I'm Raushan 👋

Senior Software Engineer · Real-Time Distributed Systems & Applied AI
📍 Bengaluru, India  ·  🎓 IIIT Una  ·  ⚡ 8 years shipping production systems

LinkedIn Portfolio Email


I build low-latency, high-throughput distributed systems — real-time messaging infrastructure, event-driven microservices, and the platform plumbing underneath them. Eight years across Oracle, PayPal, and Otis, most recently architecting notification microservices serving 400K+ daily requests under strict SLAs. Lately: agentic AI tooling — RAG, vector DBs, and MCP pointed at real operational problems.

"Learn fast && Build fast !!"


🌍 Open Source

cline/cline — the leading open-source AI coding agent (59K+ ⭐ · 6K+ forks) Active contributor since Feb 2026 with 12 merged pull requests: prompt history navigation, Gemini 3.1 Pro model support, i18n fixes for non-Latin filenames, CLI formatting, and cross-platform notification fixes.
