Aspiring AI Engineer
I’m a final-year Computer Science student at Keshav Memorial Engineering College, Hyderabad. I’m interested in AI, especially building applications with language models. I’ve worked on projects like an NL2SQL agent and a COVID-19 chest X-ray classifier, and I interned at Cognifyz Technologies, where I worked with generative AI and RAG pipelines. Right now I’m building ProjectMind AI and learning more about agentic systems. I work mostly with Python, FastAPI, LangGraph and PyTorch. I’m looking for AI Engineer roles or internships where I can keep learning and build useful things.
AI/ML Engineer Intern
Cognifyz Technologies
- • Fine-tuned and integrated Generative AI models with custom validation pipelines, improving prediction accuracy by 12% over the baseline.
- • Built a RAG pipeline with ChromaDB for agentic AI query workflows, improving retrieval efficiency.
Autonomous Relational AI Agent (NL2SQL)
• Architected a stateful agentic system with LangGraph to manage multi-turn conversational SQL workflows and session state. • Built an asynchronous FastAPI backend with versioned endpoints (/api/v1), CORS middleware and Pydantic request/response validation. • Applied prompt engineering and output constraints to generate PostgreSQL-compliant SQL from natural-language queries.
ProjectMind AI: Project-Aware AI Agent Platform
• Built a project-aware AI workspace that uses RAG and vector search over repository context to answer coding questions and assist with code generation, review and testing. • Architected a Supervisor-based multi-agent workflow on LangGraph that routes tasks across Coding, Review and Testing agents, with repository retrieval and output validation. • Integrated local Nemotron inference through llama.cpp and cloud LLM APIs behind a common provider interface.
