Praveen Kumar

Architected and built a full-stack, multi-tenant SaaS platform for drone mission management featuring a geospatial waypoint engine that supports Crosshatch, Perimeter, and Grid survey patterns with real-time mission monitoring via Socket.io WebSockets streaming live telemetry every 2 seconds. Implemented a server-side Telemetry Simulator to interpolate drone movement across waypoints with realistic battery drain modeling and automated post-flight survey report generation. Ensured strict tenant isolation by embedding organizationId within JWTs and enforcing it across all Prisma queries, achieving zero cross-tenant data leakage.

Built an AI-powered RAG knowledge platform that ingests PDFs using LangChain into Pinecone with strict company- and role-based namespace isolation, enabling secure multi-tenant retrieval. Delivered natural-language Q&A through streaming Google Gemini responses over Server-Sent Events (SSE) for real-time interaction. Engineered a “Decision Supremacy” system where saved Decisions override outdated documents within the AI prompt context, ensuring responses always reflect the most current organizational thinking. Enforced end-to-end RBAC across ingestion, retrieval, and response layers, achieving zero cross-tenant data exposure.
