What I'm looking for

I seek roles building production-ready LLM, RAG and Voice AI systems with low-latency inference, collaborative product teams, and opportunities to bridge research and deployment.

I am a Machine Learning Engineer with 2.8 years of hands-on experience building and deploying LLM, RAG, NLP and Speech AI systems. My work blends research and production, focusing on scalable voice-first and generative AI solutions.

At Alten India I built RAG pipelines using LangChain, Hugging Face and FAISS, fine-tuned transformers with LoRA/PEFT, and implemented ASR and TTS systems that improved accuracy and naturalness.

I deploy ML services using FastAPI, Docker and AWS, and I optimize inference for low-latency production use — for example reducing response latency by 30% and cutting ASR WER by ~18% in a domain-specific voice assistant prototype.

I collaborate closely with product teams to deliver voice AI prototypes and production-ready ML APIs that reduce hallucinations, ground LLM responses, and provide real-time conversational experiences.
