About

Who I Am

I'm a Generative AI Engineer passionate about building intelligent solutions that blend research, real-world deployment, and innovation. My work spans Generative AI, Computer Vision, NLP, and end-to-end AI pipelines from designing algorithms to deploying production-ready systems.

With experience across healthcare, manufacturing, and automotive domains, I've built real-time RAG pipelines, 3D reconstruction systems using NeRF & photogrammetry, document processing platforms on Azure AI, and AI-powered automation tools. I hold an M.Tech in AI from BITS Pilani and am a Kaggle Master (Competitions Expert top ~0.4%, Notebooks Master top ~1.3%).

I enjoy bridging the gap between deep research and applied business impact with a strong focus on responsible, secure AI systems and governance.

llmevalkit

llmevalkit
PyPI v6.0 Active

Universal Python library for evaluating and benchmarking LLM systems across 78 metrics in 13 modules covering Quality, Hallucination Detection, Compliance, Document AI, Governance, Security, Multimodal Evaluation, AI Content Detection, Observability, Anomaly Detection, Ground Truth Testing, Conversation Evaluation, and Red Team Testing. Works fully offline or with any LLM provider, supports RAG pipelines, AI agents, document extraction systems, table extraction workflows, and evaluation without mandatory ground-truth labels.

v6.0 Highlights: Added Ground Truth Testing, Conversation Evaluation, Red Team Testing, and Table Extraction support. Expanded the framework to 78 evaluation metrics across 13 modules with offline evaluation and LLM-as-judge support for LLMs, RAG systems, AI agents, and governance workflows.

78 evaluation metrics
Offline + LLM-as-judge modes
13 evaluation modules
RAG, Agents & Table workflows
pip install llmevalkit

from llmevalkit import Evaluator

# Offline evaluation mode
evaluator = Evaluator( provider="none", preset="hallucination")
result = evaluator.evaluate( question, answer, context)
print( result.summary())

# LLM-as-judge evaluation
evaluator = Evaluator( provider="openai", model="gpt-4o-mini", preset="production")
result = evaluator.evaluate( question, answer, context)
print( result.summary())

adaptive-intelligence

adaptive-intelligence
PyPI v4 Active

Self-improving retrieval framework that learns, remembers, and connects tools. Uses reinforcement learning to pick the best retrieval strategy per query type. Connects external tools via MCP. Runs multi-round agentic retrieval. Optimizes the entire context window. Remembers across sessions. Works with any LLM — Ollama, NVIDIA NIM, Groq, Gemini, Claude, HuggingFace. Zero required dependencies.

v4 Highlights: Context engineering optimizes entire context window (chunks, memory, history, tools, prompt). MCP integration connects external tools and serves retrieval as MCP server. Agentic workflow runs multi-round retrieval with query refinement and tool calls. Persistent memory survives restart. Incremental learning continues when new documents added. RL policy learns retrieval routing, tool selection, and graph activation — all through one feedback loop.

from adaptive_intelligence import AdaptiveAI

# 3 lines to start. Learns from every query.
engine = AdaptiveAI()
engine.ingest( "./documents")
response = engine.ask( "What are the key risks?")

# v4: Connect tools via MCP
engine.add_tool( "financial", server="http://localhost:8081")

# v4: Agentic multi-round retrieval
