Featured Projects

RailVoice AI

• Developed an AI-powered multilingual railway announcement system using FastAPI, automating announce

ment generation, approval, translation, and speech synthesis.

• Built an asynchronous processing pipeline with Celery & Redis, integrating Gemini AI for announcement

generation and Sarvam AI for multilingual translation and TTS.

• Designed RESTful APIs and PostgreSQL-backed services for train schedule management, human review,

playback queueing, and audio generation. Tech: FastAPI, PostgreSQL, Celery, Redis, Gemini, Sarvam AI
