MISSION ROUTE — DROP → SCAN → LOCK → FILTER → COMMAND → EXTRACT
AI Mission Route
Production AI pipeline built at NUVO AI · NUPAT — from document ingest through agentic reasoning to scaled deployment. The 3D scroll map mirrors these checkpoints.
CP_01 · DROP
Ingest
PDF + OCR fallback
PyMuPDF / Tesseract
Async document ingestion with coordinate-aware extraction, OCR fallback, and metadata preservation for evidence traceability.
CP_02 · SCAN
Index
Chunking + embeddings
PostgreSQL / pgvector
Context-aware chunking, embedding generation, and vector indexing while preserving page geometry and source coordinates.
CP_03 · LOCK
Retrieve
Dense + BM25 hybrid
Hybrid search
Multi-stage retrieval combining dense embeddings, keyword/BM25 scoring, and pgvector similarity search.
CP_04 · FILTER
Rerank
Cross-Encoder
Evidence prioritization
Cross-Encoder reranking to improve retrieval precision, evidence relevance, and LLM grounding.
CP_05 · COMMAND
Reason
LangGraph agents
Guardrails + citations
Agentic workflows with planner, search, evidence, contradiction, citation, judge, and reviewer agents with HITL approval.
CP_06 · EXTRACT
Scale
Production systems
Kafka / Redis / K8s
Distributed workloads with Kafka workers, Redis caching, Docker/Kubernetes, Nginx, and observability.
COMBAT LOG
Mission Combat Log
Software Developer I – AI/Backend
NUVO AI, Meril Group
Apr 2026 – Present
- Architected NUPAT Live — multi-module patent intelligence platform decomposed into Node.js microservices, shared @nupat/* packages, and BFF + Express backend
- Built production Agentic AI stack: async PDF/OCR ingestion, pgvector indexing, hybrid RAG, Cross-Encoder reranking, and LangGraph multi-agent workflows
- Implemented real-time team collaboration — live cursors, Socket.IO presence, SSE notifications, project RBAC, and Redis-backed session state
- Productionized the full stack with Docker, Kubernetes, Nginx, Kafka workers, Jenkins CI/CD, and observability across AI and backend services
Backend & Full Stack Engineer
Superceuticals Pvt. Ltd.
Aug 2023 – Mar 2026
- Scaled distributed healthcare backend to 10,000+ DAU with 99.9% uptime via Redis caching, API optimization, and event-driven architecture
- Built production GenAI/RAG systems for grounded prescription and diagnostic explanations with LangChain, ChromaDB, and safety guardrails
- Architected secure real-time APIs with Socket.IO, JWT, OAuth 2.0, and RBAC for live queues, appointments, and multi-role workflows
- Deployed backend and frontend services on AWS EC2 with Docker, Nginx, and PM2 for high availability and zero-downtime releases
- Led and mentored a 15-member engineering intern team across backend, frontend, and AI integration
