Full Stack AI Engineer

Kushagra Tiwari.

I build products that earn their place.

B.Tech graduate in Computer Science and Engineering (AI). I build production-grade GenAI systems end-to-end: agentic RAG pipelines, LLM and SLM fine-tuning, and full-stack delivery with React and FastAPI, deployed on Azure Kubernetes.

"I didn't just study AI.
I followed how it works—and it led me here."

I ground my engineering approach in the core triad of What, Why, and How. Whenever I experiment with or dissect an emerging AI architecture, my absolute priority isn't just to make it compile—it is to rigorously examine the mechanics running under the hood.

That fundamental curiosity is exactly what inspired me to build Elysium AI completely from the ground up. Rather than relying solely on high-level black-box wrappers, I engineered the causal self-attention mechanisms, tokenization matrices, and stacked transformer blocks by hand in pure PyTorch to understand the mathematical heartbeat of generation.

Production AI engineering demands strict accountability. From managing model alignment and mitigating hallucinations in edge SLMs to building optimized low-latency routing frameworks, my focus rests firmly on developing reliable, production-ready intelligent systems.

SUPPLY CHAIN AI • XGBOOST + RAG COPILOT

CPG Stockout Risk & Replenishment Copilot

An AI copilot that predicts SKU-location stockout risk for the next 7–14 days with XGBoost, explains each risk in plain English with cited evidence from supplier contracts and policies (LLM + RAG), and drafts replenishment recommendations through MCP tools. Every action needs human approval: the system never places an order on its own.

FINTECH AI • RAG PLATFORM

AI-Powered Investor Intelligence Platform

A backend platform that turns annual reports into investor insights. It ingests and chunks documents, runs semantic search, extracts KPIs with Azure OpenAI, indexes content in Azure AI Search, stores the KPIs in PostgreSQL, and serves a RAG-based chatbot and insights dashboard through FastAPI.

GENAI PLATFORM • CUSTOM GPT ARCHITECTURE

Elysium AI

Architected a custom GPT-style LLM from scratch implementing custom tokenization, embeddings, causal self-attention, and stacked transformer blocks in PyTorch. Integrated an intelligent multi-LLM router that dynamically manages request streams between Groq, Gemini, and local Ollama nodes to optimize inference pipelines.

MULTIMODAL DEPRESSION DETECTION

Psyche Track

A privacy-first screening tool that analyzes text, voice and facial expressions for early signs of depression. Text uses TF-IDF with Naive Bayes, voice uses Librosa MFCC features with a Random Forest, and the face uses OpenCV Haar Cascades with a CNN, all in a Streamlit app.

MULTIMODAL GENERATION • TEXT-TO-VIDEO & IMAGE

CineScript

An AI-powered generator that turns text prompts into cinematic video and images. Text-to-video uses the Zeroscope model, generating short clips and stitching them into a longer video, and text-to-image uses Stable Diffusion models, with prompts, negative prompts and tunable inference steps, in Hugging Face Diffusers on Google Colab.
