AI/ML Engineer
VisioApps (Louie Voice)
- Optimized LLM inference latencies from 3 to 0.7 RTF, keeping the quality conserved using TensorRT, ONNX, and vLLM.
- Self-hosted the LLM and engineered collaboratively for Voice AI backend for banking clients (served one of the major bankof India) voice integration, with prompt engineering, guardrails, RAG & databases and served by FastAPI.
- Automated the UX workflow using a deployed AI agent, reducing the work time from 15 days to 1 hr, through Gemini API.
Projects
Blog Writing Agent
- Built a multi-agent LLM system using LangGraph + LLaMA 3.3 (Groq) to automate end-to-end technical content generation (routing -> research -> planning -> execution -> aggregation).
- Engineered RAG pipeline with dynamic web search, implementing query planning, and citation grounding, improving factual reliability and reducing hallucinations in long-form generation tasks.
- Built a scalable Streamlit application with real-time execution streaming and multimodal output.
Predict Closed Questions On Stack Overflow
- Designed and trained a BERT-based 5-class text classifier for closed questions, achieving 61.7% accuracy.
- Engineered an NLP pipeline with stopword removal, stemming, tokenization, and label encoding. Implemented training utilities (early stopping, checkpoints) and evaluated with confusion matrix.
