Hello, I'm
Ranajit
Dhar
Bridging Business Logic with Autonomous AI Systems. I am an AI Architect and GenAI Engineer who builds resilient, multi-agent AI ecosystems. Coming from a Commerce background, I possess a unique advantage: I don't just write code; I engineer AI workflows that directly solve core business problems.
I specialize in moving beyond simple LLM wrappers to design fault-tolerant architectures, intelligent agentic swarms, and DevSecOps pipelines using Google Cloud. As an International Hackathon Winner, my focus is always on creating production-ready, zero-downtime systems.
⚡ What Sets Me Apart
Business + AI Architect
I bridge the gap between Code & Capital. My strategies turn AI concepts into profitable realities.
Problem Solving Mindset
From 0 to Deploy in 48 Hours.
Agentic Systems
Designing multi agent workflows for reasoning, automation, and orchestration.
Cloud Native
Deploying scalable GenAI systems using Google Cloud & serverless architecture.
