CORE · PRINCE
One engine, eight systems.
Most engineers go deep on one layer. The useful thing here is the connection between them: a backend that knows what a WebGL scene needs, an AI feature that knows how the API fails, an AR experience that ships through a real CI/CD pipeline.

NODE · FRONTEND
Frontend
Interfaces people understand in seconds
TECHNOLOGIES
- React
- Next.js
- TypeScript
- JavaScript
- HTML5
- CSS3
- Responsive design
- Bootstrap
- Tailwind CSS
- Vite
WHAT I BUILT WITH IT
- —Responsive, reusable frontend components for full-stack products, from requirements to production.
- —The Job Agent dashboard: React + Vite with a live agent log streamed over SSE.
- —This site: server-rendered Next.js with small client islands and native view transitions.
NODE · BACKEND
Backend
APIs, services and the logic in between
TECHNOLOGIES
- Node.js
- Express.js
- REST APIs
- Next.js API routes
- Serverless functions
- Server-Sent Events
- Playwright

- WebSocketsVERIFY
WHAT I BUILT WITH IT
- —REST APIs and serverless backend functions with Node.js, Express.js and AWS Lambda.
- —Backend APIs and web applications at Henceforth Solutions with Node.js, MySQL and PostgreSQL.
- —An agent orchestrator: a state machine that walks multi-page forms, persists state after every transition and recovers from loops.
NODE · DATA
Databases
Schemas, queries and caches that stay fast
TECHNOLOGIES
- PostgreSQL
- MySQL
- MongoDB
- Redis
- SQL
- Prisma
- FirebaseVERIFY
- SupabaseVERIFY
WHAT I BUILT WITH IT
- —Database design, queries, data migrations and performance optimisation in MySQL and PostgreSQL.
- —SQL optimisation and Redis caching that helped keep production at roughly 99.5% uptime.
- —A Prisma/PostgreSQL model for jobs, applications and every agent action.
NODE · CLOUD
Cloud & DevOps
Shipping it, and keeping it up
TECHNOLOGIES
- AWS Lambda
- S3
- EC2
- RDS
- Athena
- CloudWatch
- Docker
- GitHub Actions
- CI/CD
- Git
- VercelVERIFY
WHAT I BUILT WITH IT

- —Integrated AWS Lambda, S3 and EC2 into production applications; monitored them with CloudWatch.
NODE · AI
AI
LLMs, agents and retrieval — with guardrails
TECHNOLOGIES
- LLMs
- Generative AI
- AI APIs
- Conversational AI
- AI agents
- RAG
- Embeddings
- Semantic search
- AI inference
- OpenCVVERIFY
- Amazon RekognitionVERIFY
WHAT I BUILT WITH IT
- —Integrated AI services, LLMs, conversational AI and AI APIs into applications at AVRLabs.
- —Worked with AI agents, knowledge bases, embeddings and RAG-based approaches for AI-powered features.
- —A browser agent that composes answers only from known facts and never auto-answers high-risk questions.
- —Ask Prince, on this site: retrieval-first, refuses when the portfolio has no answer.
- —An OpenCV artwork-detection service in Python.VERIFY — Unverified — only in: Artwork detection service (Python)
NODE · 3D
3D / WebGL
Real-time 3D in an ordinary browser tab
TECHNOLOGIES
- Three.js
- WebGL
- Blender
- 3D modelling
- 3D asset optimisation

WHAT I BUILT WITH IT
- —Interactive 2D/3D web experiences with Three.js and WebGL for AR, virtual environments and browser-based visualisation.
- —Prepared and optimised 3D models and assets in Blender for the web.
- —Six themed Unity WebGL galleries on Artabia, patched to boot reliably across browsers.
NODE · XR
AR / VR / XR
Putting digital things into real rooms
TECHNOLOGIES
- WebXR
- webxr-polyfill

- AR.jsVERIFY
- A-FrameVERIFY
- Model ViewerVERIFY
- 8th WallVERIFY
WHAT I BUILT WITH IT
- —AR and virtual-environment experiences built on Three.js and WebGL.
