Snap Inc. Augmented Reality (AR) Development Externship

Get ready to bring your creativity to life—literally. In this externship with Snap, you’ll learn how to build your own AR Lens using Lens Studio—combining digital storytelling, interaction design, and creative code. You’ll get feedback from Snap’s team, and your final Lens will be published globally for anyone to try. This is more than just a project—it’s your launchpad into the world of AR creation.

CommunicationDigital MarketingUI/UXAugmented Reality

Overview

The externship produced a working Snapchat AR lens and a presentation that documented the design and development. Work included a review of a New York Times AR journalism feature, registering for the Snap AR Lens Challenge and installing Lens Studio, prototyping ideas, and building a VHS camcorder–style lens with a recorded demo.

Hydroficient IoT Cyber Defense Externship

Build, hack, and defend real IoT infrastructure, then hand your security playbook to an actual company. You’ll launch realistic cyberattacks, from spoofing and replay attacks to unauthorized shutoffs, and implement defenses like TLS and mTLS.

Python ProgrammingData AnalysisThreat ModelingDashboard Development

Overview

The project simulated the Grand Marina Hotel's HYDROLOGIC IoT system and produced concrete defenses and artifacts. Work included a STRIDE-based threat model with prioritized threats, a defended MQTT pipeline with TLS and mTLS, experiment results measuring replay defenses and TLS performance, and a browser-based security dashboard with a presentation of findings.

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

The work prototyped AI-driven document intelligence for pharmaceutical PDFs, producing code and walkthroughs that spanned OCR, layout-aware extraction, and RAG retrieval. Deliverables included tokenization and attention summaries, Python preprocessing and PyMuPDF extraction logic with regex heuristics, an OCR comparison, and multiple RAG configurations with reranking logs.

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

What I've accomplished

I delivered end-to-end artifacts: LLM tokenization and attention summaries, Python data-cleaning and image-preprocessing scripts, PyMuPDF extraction logic with regex and positional heuristics, an OCR evaluation report, and multiple RAG pipelines with reranking logs and a Colab walkthrough.

Project breakdown

The submission summarized how LLMs tokenized text into numeric representations, used Transformer self-attention to retain context across sequences, and underwent pretraining then human-guided fine-tuning to improve responses.

The module presented messy CSV, nested JSON, and a noisy scanned document. I inspected types, corrected column formats, flattened JSON to a DataFrame, standardized text (encoding, contractions, currency), and applied denoising, CLAHE, and Otsu thresholding to improve OCR readiness.

The project processed a multi-page SDF with PyMuPDF to extract words and bounding boxes, used regex and positional logic to identify manufacture/expiration dates, lot numbers, vendor name, and document type, and adjusted patterns to capture compact YYYYMMDD dates.

I evaluated Tesseract, PaddleOCR, and EasyOCR on a supplier PDF. I ran each tool, noted setup issues and OCR errors, and concluded PaddleOCR preserved layout best while Tesseract handled some digital-text quirks and EasyOCR offered lightweight extraction.

A project used a pharmaceutical SDF to build a RAG pipeline. I chunked pages with PyMuPDF, generated embeddings with all-MiniLM-L6-v2, implemented hybrid (vector + BM25) retrieval, and applied reranking. The deliverable included retrieval outputs and a Colab walkthrough.

The project compared three RAG configurations on a sample SDF document, logging retrieved chunks, best excerpts, and confidence. I ran a baseline, a threshold-filtered run, and a reranker-enhanced run; the reranker produced the clearest top chunk and highest confidence.

For a bundled 10-page PDF, I extracted page-level metadata, detected document boundaries, and assigned document IDs and types. The output listed each page with its Document ID and Type, producing a structured map of the file.

I set up a Gradio chat UI and backend prompt handler, extracted text from uploaded PDFs with PyMuPDF (with OCR fallback), connected retrieval and a local Mistral model, added multi-PDF upload, a loading indicator, custom theme, and a processing-status box. The app returned context-grounded answers…
