What am I Doing Lately

I am currently developing a personal microservice platform built around ZITADEL-based SSO for identity and access management.

The system leverages Web Push (PWA-style notifications) to deliver real-time VPS status and system events directly to my iPhone with minimal latency.

In parallel, I am integrating a Discord bot with an Ollama-powered LLM agent, allowing me to query VPS status and infrastructure information through natural language conversations.

This project focuses on infrastructure observability, secure access control, and AI-assisted system interaction.

  • Containerization: Docker, Docker Compose (Dockerfile & Multi-stage builds)
  • Orchestration: Kubernetes (K8s), Helm Charts (Homelab experience)
  • OS: Linux (Ubuntu/CentOS), WSL2, Shell Scripting
  • CI/CD: Git, GitHub Actions

Backend & Security

  • Languages: Python, Node.js, PHP
  • Frameworks: FastAPI, Flask, Express.js
  • Database & ORM: MySQL, Redis, SQLite, Prisma ORM
  • Security Protocols: OIDC, OAuth 2.0, SSO implementation

Client & Tools

  • Desktop/Game: Electron, Tauri, Godot 4 (GDScript)
  • Tools: Postman, VS Code, Nginx (Reverse Proxy)

Selected Projects

Blockchain & LSTM Carbon Trading Platform

Tech Stack: Node.js (Express), Prisma ORM, MySQL, Blockchain (Ganache), LSTM Model

  • System Architecture Design: Designed layered architecture (Service Layer Pattern), integrating API layer, database (MySQL/Prisma), and blockchain contracts (Ganache).
  • Backend Core Development: Used Express.js with Prisma ORM for type-safe database operations, managing users, orders, and carbon credit inventory lifecycle.
  • Transaction Security: Integrated LSTM model for anomaly detection in orders, automatically triggering freeze mechanisms before matching transactions.

Custom SSO Identity Provider

Tech Stack: Python, OIDC, OAuth 2.0, Docker

  • Built OpenID Connect-compliant authentication system from scratch without third-party services (like Auth0).
  • Implemented full OAuth2 Authorization Code Flow with Access Token and Refresh Token issuance and validation.
  • Solved cross-service single sign-on challenges and containerized deployment.

Homelab Infrastructure

Tech Stack: Kubernetes (K8s), Linux, Docker Compose

  • Built and maintained personal microservices lab, practicing Infrastructure as Code (IaC) concepts.
  • Used K8s to manage multiple service nodes, configured Nginx Ingress for traffic routing.
  • Monitored system resources with Grafana/Prometheus (PoC stage) to ensure service stability.

Minato Shigure Discord Bot

Tech Stack: Python, Discord.py, LLM Integration

  • Developed Discord bot with community management features.
  • Currently integrating Generative AI (LLM) and ComfyUI API for automated content generation to enhance community interaction.
