Selected Work

Selected builds that show how I approach security, AI, and systems work

These are the public projects that best represent the technical side of the portfolio right now, with a bias toward clear scope, strong engineering fundamentals, and honest framing.

Educational security tooling

RFID Security Toolkit

Authorized-lab tooling for studying legacy physical-access weaknesses, with Wiegand decoding, MIFARE Classic analysis, and safety-bounded lab guidance.

View Repo

Python CLI tooling Raspberry Pi GPIO RFID / access control

Decodes 26-bit Wiegand frames with parity checks and optional Raspberry Pi GPIO capture.
Parses MIFARE Classic dumps, validates access bytes, and flags default trailer keys from a dictionary.
Pairs code with lab-safe scenario docs and mitigation guidance for defenders and instructors.

Privacy-conscious computer vision

Face Security Pipeline

On-device identity verification pipeline with YOLOv8 face detection, embeddings, optional anti-spoofing, and FastAPI delivery.

View Repo

Python FastAPI YOLOv8 facenet-pytorch ChromaDB

Keeps biometric embeddings local and exposes metadata only, not raw vectors, to clients.
Supports alignment, cosine-similarity identity verification, optional anti-spoof scoring, and MJPEG/WebSocket streaming.
Includes optional PostgreSQL attendance logging while preserving a privacy-first default posture.

PyTorch vision toolkit

Neural Style Transfer Toolkit

Production-oriented neural style transfer toolkit spanning classical Gatys optimization, fast AdaIN, and temporally stabilized video stylization.

View Repo Live / Docs

Python PyTorch Streamlit Docker Next.js project hub

Implements multiple stylization modes including Gatys, AdaIN, and video pipelines with temporal smoothing.
Ships CLI entrypoints, a Streamlit demo, and Docker support for reproducible experimentation.
Separates the heavy vision toolkit from a lightweight Next.js project hub used for docs and presentation.

Protocol engineering demo

bitcoin-node-pure

Learning-oriented Bitcoin codebase that keeps core cryptography and transaction logic stdlib-only while layering a friendlier CLI on top.

View Repo

Python secp256k1 primitives P2P networking SQLite cache

Covers ECC, hashes, legacy transactions, and P2P framing under a clean package structure.
Adds a richer CLI with environment checks, key generation, tx encoding flows, and peer diagnostics.
Positions scope honestly as an engineering demonstration rather than a full consensus node.
