Systems I’ve built and explored

A selection of things I’ve built across software systems, cybersecurity, applied AI, and mobile AR. Each project includes the architecture, tools I used, and source code when available.

Security Software

SafeView

Real-Time Visual Phishing Detection

A Windows security agent that scans active screen buffers using Tesseract OCR and semantic embeddings to detect visual phishing with local, sub-50ms inference and no cloud data transmission.

Problem: Visual phishing can appear inside a rendered interface before URL-focused controls provide enough context.
Decision: Keep capture, OCR, and semantic comparison on-device using active screen buffers, Tesseract, and sentence embeddings.
Outcome: Sub-50ms local inference without transmitting screen data to a cloud service.

OvaLens computer vision and conveyor architecture

Computer Vision & IoT

Automated duck egg candling and fertility sorting powered by a fine-tuned, ONNX-quantized YOLOv8 model on Raspberry Pi, NEMA stepper motor conveyor orchestration, ESP32 microcontrollers, and an offline-sync control architecture.

Problem: Duck-egg candling required reliable computer vision classification under controlled camera exposure, synchronized conveyor sorting on low-power edge hardware, and uninterrupted operation despite intermittent connectivity.
Decision: Fine-tune YOLOv8 on a custom dataset with hyperparameter optimization, quantize via ONNX for Raspberry Pi execution, orchestrate NEMA stepper drivers and ESP32 actuators, and engineer a native edge app with offline synchronization.
Outcome: Sub-50ms inference on low-power edge compute, synchronized mechanical sorting via stepper and servo actuation, and local data persistence that syncs automatically when reconnected.

Full-Stack SystemDiscontinued

Pickle World

Real-Time Venue Booking Engine

The hosted deployment was retired after its domain and hosting were not renewed.

A multi-court reservation engine featuring WebSocket slot locks, webhook-driven payment reconciliation, and strict MySQL transaction isolation to prevent double-booking under concurrency.

Problem: Concurrent customers can attempt to reserve and pay for the same court slot at nearly the same time.
Decision: Coordinate WebSocket slot locks with payment webhooks and strict MySQL transaction isolation.
Outcome: The booking flow was designed to prevent double-booking while reconciling payment state.

Reverse Proxy & Streaming Engine

Retired because its scraper depended on unlicensed third-party media sources.

An ad-free streaming architecture using a custom Node.js reverse proxy for byte-range video streaming, automated scraping workers, Redis caching, and a relational PostgreSQL schema.

HLS proxy request, relay, and CDN architecture

Backend InfrastructureDiscontinued

HLS Proxy Server

Streaming Relay & Cache Layer

Retired with myAnime because it supported delivery from unlicensed third-party media sources.

A Node.js and Express HLS relay that rewrites manifest URLs, forwards byte-range requests, streams binary segments with backpressure, combines memory and disk caching, and rejects basic private-network targets.
