At Code Garage Tech, I designed and managed AWS EC2 infrastructure with Auto Scaling and RDS/Aurora to support 5K+ users. I also automated three-hour EC2 sessions, reducing infrastructure costs by 30–40%.
I developed Node.js and Python APIs for WhatsApp messaging, SMS, and call automation, and collaborated on React.js frontend development. My work includes AI-driven voice workflows using LiveKit, conversational LLMs, and OpenAI API fallback.
On Social Hub, I engineered real-time chat and WebRTC video calling supporting 500+ concurrent connections. I also built features for social interaction and used BullMQ and Redis for background processing.
