Things I've built and kept running

10 projects, from two platforms live in production to Laravel business systems and a capstone that won best paper. Each one lists exactly what I did on it.

PandaAuth Key System Service

Featured

Full-stack developer & QA analyst · 2022 — Present

Authentication and licensing platform handling registration, license validation, and entitlement checks for real users. I built the API layer, run the QA pass on every release, and manage the Linux/Nginx VPS it runs on.

Clinic Web Application

Featured

Backend developer (internship) · 2025 — 2026

  • Reporting across 3–24 months with trend analysis, category matrices, and CSV/JSON export

Point of Sale System

PHP developer

Counter-facing point of sale built in Laravel — product lookup, cart, discounts, payment, and printable receipts, with a daily sales summary for the owner. Developed and tested locally on a XAMPP stack.

VeggieScan

Capstone lead developer · 2026

Visual diagnosis web app that grades vegetable freshness and flags contamination from a photo. YOLOv8 handles detection; an LLM turns the model output into a plain-language verdict and handling advice.

status Awarded Best Paper Presentation

What I did

  • YOLOv8 training pipeline on a hand-labelled vegetable dataset
  • LLM reasoning layer for verdicts and storage suggestions
  • Web interface for upload, results, and diagnosis history

VeggieScan R35

Mobile & ML developer · 2026

React Native app that grades carrot freshness through the phone camera. A custom-trained YOLOv8-OBB model returns a class, a confidence score, and a 0–100 Numerical Freshness Score with an eat-or-discard recommendation — over REST for single photos, over WebSocket for a live camera feed.

status Capstone research, co-authored

What I did

  • React Native client using Vision Camera for live capture and single-image upload
  • FastAPI backend serving the YOLOv8-OBB model over both REST and WebSocket
  • Dataset annotated in Roboflow with oriented bounding boxes across four classes, oversampled to balance them
  • Model trained on Colab GPU with Drive checkpointing, plus the 0–100 freshness scoring system

Skycloud .NET Obfuscator

C# developer · 2019 — 2020

Open-source obfuscator for .NET assemblies, written in C#. It is the most-starred thing I have published — 7 stars and 2 forks. I discontinued it in 2020 over security concerns rather than keep circulating a tool I no longer stood behind.

C#.NET

status Open source · my most-starred repo

What I did

  • Around 120 KB of C# working against compiled .NET assemblies
  • Released the full implementation publicly rather than shipping binaries only
  • Retired the project in 2020 once I judged the security tradeoffs unacceptable

More on GitHub and GitLab

Over 50 more repositories — mobile apps, YOLOv8 training tools, C# desktop utilities, and coursework.
