Hi, I'm

Mohamadh Harrish.

I turn business challenges
into technology solutions.

From shipping Angular features to 10,000+ enterprise customers at Caterpillar, to building compliance-aware LLM systems from scratch — I operate at the intersection of software engineering, AI, and real-world business impact.

01. About Me

I'm a software engineer and technology consultant based in Richardson, TX who leads with the business problem — then designs the right technical solution. I care as much about why something is built as how.

At Caterpillar Inc., I didn't just ship features — I identified operational bottlenecks, proposed solutions to stakeholders, and delivered systems that served 10,000+ enterprise customers, cut costs by $200,000 annually, and drove adoption across 15 teams.

Today, I apply AI, cloud, and full-stack expertise to tackle real-world challenges — from compliance in regulated industries to scaling infrastructure — always anchored in measurable business outcomes.

Things I've built

Document QA RAG System

Retrieval-Augmented Generation Pipeline

Built an end-to-end RAG pipeline using Python, LangChain, and FAISS that ingests PDF and text documents, chunks and embeds content via OpenAI embeddings, and returns source-grounded answers to natural-language queries.

Implemented a React + FastAPI interface for document upload and live Q&A with streaming responses; vector similarity search reduced hallucination and improved answer precision over baseline prompting.

Built and deployed a full-stack app that fetches YouTube transcripts via the Supadata API and generates structured summaries using Groq's LLaMA 3.3 70B model, with multi-language fallback support.
