AI Engineer at Ethertech Innovations building TrainLab.ai and production LLM systems for healthcare.

India

Message

At Ethertech Innovations Pvt. Ltd., I’m the technical lead for TrainLab.ai, a no-code platform supporting 23+ AI/ML tasks across vision, NLP, LLM, multimodal, and tabular domains. I delivered its task-specific data modeling, validation pipelines, GPU inference orchestration, and chat/API model interfaces.

For Kognitic, I fine-tuned a Qwen 27B extractor in a neuro-symbolic pipeline that produces structured clinical outcomes at 96–98% validated accuracy, replacing the incumbent vendor. I also built automated AWS clinical-data pipelines and evaluation workflows that anchor extracted values to source evidence.

I’m currently building Agntly, a chat-driven agentic microapp platform with supervisor/sub-agent orchestration. Earlier, at Jio Platforms Ltd., I led full-stack product development for high-volume, low-latency systems; I’ve also worked on healthcare, banking, and education-tech products. Seven of my patents have been filed, with two granted.
