Project details
YOUR DATA ISN'T JUST DIRTYIT'S COSTING YOU DECISIONS.
Missing values. Duplicates. Wrong formats. Outliers. Most people ignore these and build on bad data. I don't.
I clean your data from scratch and then analyze what it's actually telling you.
WHAT YOU GET:
Data Cleaning (duplicates removed, missing values handled, format fixed)
Exploratory Data Analysis (trends, patterns, comparisons)
Professional visualizations (charts that actually make sense)
A clean, usable dataset + analysis report
Clear summary of what your data means
HOW IT WORKS:
1. You send me your data (Excel, CSV, Google Sheets, SQL)
2. I tell you what I find (missing values, data quality issues)
3. I clean it, analyze it, visualize it
4. You get: clean dataset + detailed PDF report + Jupyter notebook
TOOLS: Python, Pandas, NumPy, Jupyter Notebook
WHO THIS IS FOR:
Startups trying to understand their customer data
Businesses with messy spreadsheets
Anyone who has data but isn't sure what to do with it
Teams that need a clean dataset before building dashboards or reports
The difference? I don't just clean explain. You'll understand what your data means, not just have a cleaned file.

About Md. Mehadi
AI Chatbot & Agent Developer | RAG, LangChain, FastAPI, OpenAI API
Sirajganj, Bangladesh - 11:35 am local time
I help startups, founders, and businesses build AI-powered solutions that go beyond simple chatbots. My focus is on developing AI chatbots, AI agents, RAG-based applications, custom AI assistants, and scalable backend APIs that integrate with modern LLMs and business workflows.
My technical stack includes Python, FastAPI, LangChain, LangGraph, OpenAI, LlamaIndex, ChromaDB, Pinecone, Weaviate, SQL, MongoDB, Docker, Git, and REST APIs. I also work with Retrieval-Augmented Generation (RAG), vector databases, prompt engineering, AI workflow automation, and Model Context Protocol (MCP) for building reliable AI systems.
Although I am at the beginning of my freelance journey, I have invested significant time building personal and portfolio projects to strengthen my practical skills. Every project focuses on writing clean, maintainable code, creating scalable architectures, and solving real business problems with AI.
I can help you with:
• AI Chatbots powered by OpenAI and RAG
• AI Agents using LangGraph and modern agent frameworks
• FastAPI backend development for AI applications
• OpenAI API integration and custom AI assistants
• LangChain and LlamaIndex applications
• Vector database integration (ChromaDB, Pinecone, Weaviate)
• AI workflow automation and backend APIs
I value clear communication, honest collaboration, and long-term client relationships. If you're looking for someone who is committed to delivering well-structured AI solutions and continuously improving with every project, I'd be happy to discuss how I can help.
