About

From full stack to AI engineering.

Full Stack Developer with 5+ years of experience building and deploying scalable web applications with React, Next.js, Node.js and NestJS. Now moving into AI engineering, working on agentic AI systems, RAG pipelines, fine-tuning and LLM-powered applications.

In agentic AI, I build agents that plan a task, call tools such as search or APIs, and work through multiple steps, using LangGraph, the OpenAI Agents SDK and MCP. Recently built DealDesk, a LangGraph system of eight agents: safety guard, researcher, negotiator, fact checker, limit checker, closer, simulator and judge. I also build RAG pipelines with ChromaDB and embeddings, and fine-tune open-source models with LoRA/QLoRA.

Projects

AI projects I have built.

Agents, RAG systems and automation workflows. Code for most of them is on GitHub.

Multi-agent system

DealDesk

A LangGraph system of eight agents: Safety Guard, Researcher, Negotiator, Fact Checker, Limit Checker, Closer, Simulator and Judge.

Hard limits are enforced in plain code, not by the AI.

Tested with a weighted scoring rubric comparing safety off and safety on runs.

  • LangGraph
  • FastAPI
  • Next.js
  • Supabase
  • Groq
  • Ollama
  • Tavily
GitHub
Local RAG with evaluation

RAG Lab

A fully local RAG system with an evaluation dashboard, built without LangChain.

Ollama (llama3.1:8b) for generation, nomic-embed-text for embeddings and ChromaDB as the vector store.

Evaluated with MRR, nDCG, keyword coverage and LLM-as-judge scoring.

  • Ollama
  • nomic-embed-text
  • ChromaDB
  • FastAPI
  • Next.js
Live demoGitHub
ReAct agent

Research Assistant Agent

A ReAct agent built from scratch in Python.

Multi-tool routing (calculator, web search, unit converter) with multi-step reasoning.

Iteration limits, error handling and a reasoning trace log.

  • Python
  • ReAct
  • Tool calling
GitHub
Document Q&A

RAG Chatbot

Answers questions over documents with source attribution.

Keeps conversation memory between turns.

Applies a confidence threshold on retrieval distance.
