About me

Hands-on experience attacking and defending IoT systems, plus a practiced security playbook for real infrastructure.

I am an early-career cyber defense enthusiast with hands-on experience from an IoT security externship. I learned attack techniques such as spoofing and replay, and implemented defenses including TLS and mutual TLS while documenting a security playbook for real infrastructure.

Pfizer Advanced: AI-Powered Document Insights & Data Extraction Externship

Prototype AI-powered document intelligence with Pfizer—using OCR, LLMs, and RAG to automate real enterprise PDF workflows and build a standout portfolio project.

AI & MLPythonDocument IntelligencePresentation Skills

Overview

This externship prototyped an AI document-intelligence pipeline combining OCR, large language models, and retrieval-augmented generation to process enterprise PDFs. The work documented how core LLM components function and how they integrate with OCR and retrieval services. Deliverables included conceptual diagrams and a technical explanation of LLM mechanics.

What I've accomplished

I summarized LLM internals, explaining tokenization, embeddings, positional encoding, self-attention, and autoregressive next-token prediction as the basis for model capabilities.

Project breakdown

I summarized LLM internals, describing tokenization, embeddings, positional encoding, self-attention, and autoregressive generation, and noted that capabilities arise from next-token prediction.

I worked in Google Colab to run Python notebooks, debugged Pandas parsing errors, processed JSON snippets, performed text cleaning, and applied OpenCV thresholding to enhance a scanned document for OCR. Deliverables included multiple Colab and Drive files.
