Portfolio

Web platform

SumaiMatch

A home-building matchmaking service. Visitors answer a one-minute questionnaire, and an AI suggests the model-home exhibitions that suit them, from about 500 in Aichi Prefecture. A personal page lets them compare, save favourites and track consultations with builders.

Android app

Keepi

An AI notes app. Speak, type or snap a photo, and its assistant files it as a to-do, a note or a journal entry. The journal is locked behind fingerprint or PIN and kept out of AI summaries.

Nilesh Patil’s own product, live on Google Play.

Web app

ProductCompare AI

Paste up to four Amazon India or Flipkart links and it lines up price, rating and specifications side by side, then explains the trade-offs in plain words. If a retailer doesn’t publish a detail, it leaves the field blank rather than guessing.

Open-source package

telegram-slack-mcp

MCP servers that connect Claude to your own Telegram and Slack chats: real conversations, not a bot inbox.

Nilesh Patil’s open-source package, on npm and PyPI, MIT licence.

Built with npm, PyPI, MCP

Machine learning

Native language from spoken English

Listens to five seconds of English and predicts whether the speaker’s first language is Hindi, Kannada, Malayalam, Tamil or Telugu. A fine-tuned Wav2Vec2 model reached 92.19% accuracy on held-out test clips, and the repo logs every experiment, including the ones that didn’t help.

Harsh Sahu’s machine-learning project. The code and the experiment log are public.

Built with PyTorch, Wav2Vec2, torchaudio

AI agents

AI Travel Agent

A multi-agent trip planner. A supervisor sends each request to flight, hotel, weather, budget and itinerary agents, a guardrail screens what comes in, and the draft plan waits for a person’s approval before it’s final. Paused plans are saved in PostgreSQL and pick up where they stopped.

Jatin Thakur’s open-source project.

Built with LangGraph, Groq, MCP, FastAPI, PostgreSQL, Docker

AI agents

Backstory consistency checker

A multi-agent retrieval system that checks whether a character’s backstory contradicts the novel it comes from.

Built with scikit-learn, Streamlit, pytest, GitHub Actions

Voice app

DukaanMitra

A shop ledger for kirana stores. Say it in Hindi, Hinglish or English, “Ramesh ko 500 rupaye udhaar”, and it shows exactly what it understood before anything is saved.

Harsh Sahu’s project.

Built with Streamlit, Sarvam AI, SQLite

AI agents

AgentRAG

Question-answering over your own documents, where each retrieved passage gets its own agent. The agents work in parallel, cross-check each other’s findings, and a final agent writes the answer, streamed live.

Nilesh Patil’s open-source project, MIT licence.

Built with Python, Gemini, ChromaDB, TypeScript

Aura

A voice-driven agent that operates a Windows PC. It reads the screen, plans the steps, then moves the mouse and types to finish the job, and it stops at the payment step to ask first.

Campus Bazaar

A buy-and-sell marketplace for college students: listings with photos, real-time chat between buyer and seller, and an admin panel for users and listings.
