About Me
Building the future of
intelligent, immersive systems
I’m an AI Solutions Architect specialising in agentic AI pipelines, conversational AI systems, immersive XR platforms, industrial digital twins, and real-time voice-driven interfaces. I architect end-to-end solutions that are built to scale, built to last.
My track record spans production-grade systems for global enterprises including Airbus, Deutsche Bahn, Starbucks, Koch, Flinthill Resources, and Invista — spanning aerospace, rail, industrial, and consumer domains.
I enjoy building products from the ground up — from validating ideas through rapid prototyping, testing with real users, and delivering scalable, high-performance systems that connect people, data, and environments in powerful new ways.
My work sits at the intersection of two worlds that rarely converge — deep XR engineering and applied AI architecture. The goal isn’t to integrate AI into experiences — it’s to design systems where AI and immersion are inseparable.

How I design AI systems
When architecting an AI solution I think in layers — each one solving a distinct problem. What makes my approach different is that every layer is also designed to surface inside a real-time human experience, not just run as a backend service.
LLM Orchestration & Tool Use
The reasoning core. Deciding when to call tools, which model fits the task, how to constrain outputs to stay grounded and safe, and how to handle tool failures gracefully.
In immersive use
Powers intelligent avatar responses, context-aware NPC behaviour, and adaptive training flows in real timeMulti-Agent Coordination
Breaking complex problems into specialised agents with clear responsibilities — a tutor agent, an evaluation agent, an emotion agent — each doing one job well, orchestrated by LangGraph.
In immersive use
Multiple agents running simultaneously — one listening, one evaluating emotion, one generating the avatar’s next responseMemory Architecture
Short-term context for the current session. Long-term persistence across sessions via database checkpointers. The difference between an AI that feels present and one that forgets you.
In immersive use
Avatar remembers previous training sessions — what the learner struggled with, what topics are complete, how to adapt the next sessionRAG Pipelines & Vector Retrieval
Grounding responses in trusted knowledge — chunking, embedding, semantic search, and retrieval. Ensures the AI speaks from your data, not from hallucination.
In immersive use
Industrial digital twins retrieve live equipment specs. Training avatars pull curriculum knowledge. VR assistants answer from product metadataReal-Time Interaction Layer
Voice pipelines (STT → LLM → TTS), WebSocket streaming, low-latency response design, and emotion detection. This is where AI stops being a service and becomes a presence.
In immersive use
3D avatars that speak, listen, respond to emotion, and lip-sync in real time — creating a genuinely human-feeling AI interaction inside XRCloud-Native Deployment
Containerised services, managed vector stores, observability via LangSmith, responsible AI guardrails, and scalable infrastructure that holds under enterprise load.
In immersive use
AI backend serving 1,000+ concurrent XR users with monitored, traced, and auditable agent interactions across every sessionWhere AI meets immersion
Most AI architects build pipelines. Most XR developers build environments. I build systems where the pipeline is the environment — where the AI response becomes the avatar’s voice, the training scenario’s outcome, or the digital twin’s next state.
Intelligent XR Training
AI-powered virtual mentors that replace scripted flows with natural conversation — learners ask anything, get grounded, contextually accurate answers in real time.
Industrial Digital Twins
Physical systems mirrored in XR — engineers interact with live equipment data, get AI-generated operational guidance, and control real hardware from inside VR.
Emotionally Aware AI Tutoring
A 3D teacher avatar that listens, detects emotion, retrieves curriculum knowledge, and adapts its teaching style — remembering each student across every session.
Context-Aware NPC Systems
Virtual characters that don’t follow scripts — they reason about their environment, respond to user intent, and maintain consistent personality across interactions.
Featured Project
Currently building
AI Tutoring Platform
Founder & Architect — 2026 – Present
- Architecting a full-stack AI tutoring platform featuring a 3D conversational teacher avatar with real-time voice interaction and emotion-aware responses.
- Designed a multi-agent orchestration pipeline using LangGraph, integrating LLM reasoning, speech (STT/TTS), and emotion detection for adaptive learning experiences.
- Built end-to-end system across Unity (XR interface), Node.js backend, and cloud infrastructure (PostgreSQL, Redis, Firebase, AWS/GCP).
- Implementing RAG-based knowledge retrieval using vector embeddings and ChromaDB for context-aware and reliable responses.
- Designed for global accessibility with multilingual support — English and Hindi at launch, with additional languages planned.
