"Code. Break. Fix. Ship. Repeat."
I'm a Full Stack Developer, AI Engineer, and relentless builder with a deep focus on Generative AI, Agentic AI systems, and production-grade LLM applications. I don't just learn technologies — I build real things with them, from RAG pipelines to autonomous agents, from console games to full-stack platforms.
Currently pursuing B.Tech in Computer Science & Engineering at Academy of Technology (AOT), Kolkata.

🐉 Chimera-CLI — AI-Powered Docker Config Generator
Go · Cobra · Bubble Tea · Multi-LLM · Docker
A developer CLI tool that autonomously analyzes GitHub repos and generates production-ready Docker configurations. Point it at any repo — it clones, detects frameworks (Express, Next.js, React, FastAPI, Flask, Django), validates findings via LLM, and spits out optimized multi-stage Dockerfiles + docker-compose configs. Supports OpenAI, Anthropic, Groq, Gemini, and Ollama as LLM providers.
