I build production-grade AI systems — not just demos. My work spans fine-tuning TTS models for real-time voice pipelines, designing multi-agent LangGraph workflows, and deploying low-latency FastAPI backends for conversational AI.

Currently exploring: Agentic AI · RAG Systems · LLM Fine-tuning · Voice AI

AI Intern — Hiyvr.ai (Ethical Den) Jul 2025 – Sep 2025

• Fine-tuned Orpheus TTS model for Bengali customer support with 6-7s end-to-end latency in a real-time multi-call pipeline
• Benchmarked open-source Bengali LLMs across accuracy, response quality, and latency for production deployment
• Integrated Twilio and Ngrok for real-time communication, cutting setup time by 40%

Summer IS Intern — Indian Oil Corporation Ltd. Jun 2024 – Jul 2024

• Built "Doc Connect", a doctor appointment management system using .NET, SQL, HTML, CSS, JS
• Implemented role-based authentication and secure access control
