BrainBuzzAi
Personal Project — AI Playground & Learning Sandbox
A full-stack AI-powered learning platform built end-to-end as a solo engineer — from React Native mobile app to production MCP server infrastructure on AWS. This is where I prove that agentic AI works reliably in production, not just in demos.
Architecture Overview
Agentic Content Pipeline
Topic ingestion → LLM agent orchestration → structured output (learning paths, flashcards, quizzes, MCQs) with zero manual content creation.
Production MCP Interfaces
Architected and implemented MCP server/client interfaces exposing the platform's learning management APIs for AI agent consumption — a real-world proving ground for production MCP patterns.
Full-Stack Mobile + Web
React Native mobile app (iOS & Android), web admin panel, REST API backend, and PostgreSQL database — all built end-to-end as a solo engineer.
Production Infrastructure
Deployed on AWS EC2 with Nginx reverse proxy, SSL termination, and horizontal scaling strategy (auto-scaling groups + load balancer) to handle traffic spikes.
Multi-Agent Coordination
Actively iterating on agentic memory, tool-routing, and multi-agent coordination using Claude API, OpenAI API, and LangChain.
Live for Real Users
Not a demo or proof-of-concept — a live product being used by real users to learn and prepare for exams through AI-generated content.

Core Focus
Results-driven Tech Lead with 9+ years of experience building production-grade distributed systems across web, mobile, and cloud. Frontend-heavy full-stack engineer with deep roots in React and React Native, and solid DevOps exposure across AWS EC2, Nginx, and CI/CD pipelines. Recently pivoted strongly into Agentic AI — specialising in Model Context Protocol (MCP) server/client architecture, multi-agent orchestration, and LLM tool-use. Currently leading engineering at SurveyMonkey while exploring the AI frontier through personal projects. Passionate about building autonomous AI systems that work reliably in production, not just in demos.
