πŸ‘‹ Hello, I'm Nitin Singh

Typing SVG

BTech in Artificial Intelligence & Data Science Β· 2 years as an AI Engineer. I build production-ready systems: multi-agent LLM pipelines, generative AI (LoRA training, diffusion, video generation), and full-stack AI products. Based in India.


What I Build

πŸ€– Agentic & LLM Systems β€” Multi-agent pipelines (LangGraph), RAG with structured evidence passing, fine-tuning with SFT + GRPO on Qwen and Llama models

🎨 Generative AI & Vision β€” LoRA training pipelines (Kohya_ss β†’ SD / FLUX.1), text-to-video (Wan2.2), computer vision (CLIP Β· RetinaFace Β· YOLOv5)

πŸ—οΈ Full-Stack AI Products β€” FastAPI + Next.js + PostgreSQL, deployed apps on Render, deterministic safety layers over LLM outputs

πŸ“Š Data & Financial ML β€” Time series forecasting, crypto/retail analytics on Snowflake, clustering and EDA pipelines

Projects

πŸ€– Agentic & LLM Systems

Project What it does Stack
Multi-Agent RAG Three-agent literary consistency pipeline: Llama 3.3-70B decomposes claims into atomic facts, Qwen3-Embedding-8B retrieves evidence from a Pathway vector store, DeepSeek-R1 judges contradictions. Structured Python object passing preserves similarity scores and claim provenance across agents. 98.3% success rate on 60 test cases. IIT Kharagpur Hackathon Llama 3.3, DeepSeek-R1, Qwen3, Pathway
BTC-Forecaster Fork of TradingAgents repurposed for intraday BTC forecasting. Multi-agent pipeline: technical + news + sentiment analysts β†’ bull/bear debate β†’ trader β†’ risk β†’ final forecast. Emits 1h/4h price predictions with a self-scoring track record logged against realized prices. LangGraph, Python, Yahoo Finance
AMD AIPL Fine-tuned Qwen3-4B using SFT + GRPO for a 1v1 Q-agent vs A-agent tournament. Custom reward function; self-play loop where question and answer models iteratively improve each other. AMD Hackathon at IIT Bombay Qwen3-4B, PyTorch, GRPO

🎨 Generative AI & Vision

Project What it does Stack
AI-Avtaar End-to-end character pipeline: upload photos β†’ automated LoRA training β†’ SDXL image generation β†’ virtual clothing try-on. Four isolated Python environments orchestrated through a single Streamlit UI. Kohya_ss, FLUX.1 / A1111, CatVTON, Streamlit
AI Video Creator Three-stage generation pipeline: Llama 3.1-8B writes a storyboard β†’ FLUX.1-dev renders per-scene images β†’ Wan2.2-T2V animates them. Gradio tabbed interface. Tested on AMD MI300X with ROCm. Llama 3.1, FLUX.1-dev, Wan2.2, Gradio, ROCm
Gender Detection API FastAPI endpoint using RetinaFace for face detection and CLIP for gender classification. Handles multiple faces, non-human images, and mismatches as distinct typed error responses. FastAPI, CLIP, RetinaFace, PyTorch

πŸ—οΈ Full-Stack AI Products

Project What it does Stack
ResumeTeX Browser-based LaTeX resume builder: manual form, AI import from PDF/DOCX (extract β†’ parse β†’ verify pipeline), AI tailoring to job descriptions. Deterministic anti-fabrication guard restores all original facts post-AI. Deployed on Render. Next.js 14, FastAPI, PostgreSQL, Nebius LLM
Stock News Summarizer Scrapes TradingView, Finviz, and Polygon; Gemini Pro selects top articles and writes <500-word summaries with 7-day "what changed today" diffs. SQLite history, daily refresh at 8 AM IST. Free-tier deployed on Render. Flask, Gemini Pro, SQLite
Student Performance Analysis CSV upload β†’ K-Means / Agglomerative clustering β†’ per-student performance dashboard with trend charts, subject breakdowns, class comparisons, and Excel export. React, Flask, Scikit-learn, MUI

πŸ› οΈ Tooling & Extensions

Project What it does Stack
interactive-preview-skill A Claude Code skill that turns any React/Next.js codebase into an interactive, theme-matched "try it before you sign up" demo a guided product tour on mock data, auto-generated from your own UI. Leaks no backend. React, Nextjs, Tailwindcss
Support Finder MV3 Chrome extension with a four-layer deterministic pipeline: DOM scan β†’ same-domain path probing β†’ schema.org extraction β†’ confidence scoring. Returns ranked support contacts with explanations. No AI; no fabrication. TypeScript, React, MV3
android-compose-design Agent skill for Claude Code. Guides AI to produce distinctive Jetpack Compose UI intentional color, type hierarchy, shape language, and motion instead of Material 3 defaults. Jetpack Compose, Kotlin

πŸ“Š Data & Financial Analysis

Project What it does Stack
Solana Price Analysis OHLCV data (2021–2024), 44-column feature set via the ta library, ML price prediction model, and live Binance price dashboard. Python, Streamlit, Binance API
Rossmann Retail Analysis 1M+ row sales dataset: cleaning, feature engineering, EDA on Snowflake. Quantified 81.5% sales uplift from promotional periods. Snowflake, SQL
