Architected a GraphRAG pipeline with LangChain, Neo4j, Cypher, FastAPI, and LangGraph, combining entity linking, subgraph expansion, hybrid retrieval, and reranking for citation-grounded response generation over a legal knowledge graph. Established evaluation and observability with RAGAS, tracking faithfulness, relevance, F1 score, and retrieval quality to harden response reliability on ambiguous queries. Optimised local inference using GGUF/4-bit quantisation, KV cache, FlashAttention, and speculative decoding, achieving faster generation with reduced memory footprint.

Developed scalable FastAPI backend with microservice architecture, dependency injection, and layered design for maintainability and independent service scaling. Built AI-powered voice assistant using ElevenLabs Client SDK to guide users, teach vocabulary, and evaluate learning through AI-generated quizzes. Optimised performance through Redis caching, rate limiting, memoisation, and database query tuning, reducing response latency across high-traffic endpoints. Containerised with Docker and deployed via CI/CD pipelines on GitHub Actions to VPS.

Built scalable backend with Spring Boot applying layered and domain-driven design for modularity and separation of concerns. Architected stateless JWT authentication with RBAC, enabling horizontally scalable session management and secure access control. Optimised MongoDB persistence layer with indexing, connection pooling, and pagination to support high-throughput ingestion and retrieval. Engineered real-time notifications via Server-Sent Events (SSE), decoupling read-heavy streams from core paths to improve overall responsiveness.
