Systems I've shipped.

Led the development of an on-premise AI platform for secure document intelligence. Built a modular Agentic RAG system with LangChain, LangGraph, Knowledge Graphs, and hybrid retrieval strategies enabling simultaneous multi-document querying. Deployed privacy-first LLM infrastructure with Docker Compose + GPU support, bundling Llama 3.1, Ollama, and RabbitMQ. Powered by an event-driven workflow engine orchestrating 25+ microservices across OCR, LLM, RAG, and analytics with dynamic DAGs and idempotent retries.

Built an AR-based educational toy platform combining physical learning materials with a mobile app. Developed the backend using Laravel for authentication, APIs, device registration, and QR-based product verification. Implemented the frontend with Nuxt.js for the website and user management. Integrated Unity with Three.js-based 3D assets to deliver interactive augmented reality experiences. The system links physical products to digital content through QR code verification, secure device registration, and API-based communication between the Unity app and Laravel backend.

Developed a comprehensive LMS using 3-Tier Architecture: Bootstrap, Vue.js, and Inertia.js on the frontend; PHP, MySQL, and Laravel on the backend. Integrated Algolia for fast search and deployed on GCP with full admin controls, course management, and student tracking.
