About

I'm an AI Engineer focused on agentic AI workflows, LLM orchestration, and RAG pipelines. I hold a B.Tech in Information Technology from AKGEC (2026) with a CGPA of 8.2.

At Sargvision I build production LLM features with Google ADK and Vertex AI — agent-to-agent workflows, an automated blog generation pipeline, and real-time speech-to-speech voice. Previously an AI Intern at IBM, where I shipped a Python NLP and machine learning application served over FastAPI microservices.

That GenAI work sits on a full-stack foundation across Next.js, Node.js, FastAPI, PostgreSQL, and MongoDB — building clean, efficient, and scalable systems end-to-end.

Work Experience

AI Engineer Intern

Sargvision

June 2026 – Present

Building agentic AI features end-to-end on Google ADK and Vertex AI — LLM pipelines, agent-to-agent workflows, real-time voice, and the deployment path around them.

  • Engineered an LLM-powered blog generation pipeline automating content production end-to-end, from source ingestion through refinement to publishable draft.
  • Implemented agent-to-agent (A2A) workflows and custom agent skills, enabling task handoff between agents and extending built-in ADK capability.
  • Integrated Vertex AI’s Gemini Live model for real-time speech-to-speech voice conversation.
  • Contributed to the platform’s GCP deployment (Cloud Run, Firestore) and GitHub Actions CI/CD pipeline with an automated agent-evaluation gate.
  • Built and refined UI components to surface, control, and review AI-generated content within the product.

AI Intern

IBM (Project-Based)

Sep 2025 – Oct 2025

Engineered a Python-based NLP and machine learning application end-to-end, achieving reliable real-time classification in production-style usage.

  • Owned the full modelling loop — problem decomposition, feature and data design, and model evaluation — to achieve reliable real-time classification.
  • Designed data preprocessing, validation, and ETL pipelines feeding the model.
  • Deployed model predictions through FastAPI RESTful microservices, applying systematic debugging to isolate and resolve reliability issues under real usage.
