I poke around, break things, fix them, and occasionally convince a server to behave. Mostly just here to see what happens next.

Build. Break. Rebuild. The ouroboros is a reminder that systems are never finished objects: they loop through failure, repair, and renewal. I learn by running the cycle again, making each version more resilient than the last.

Homelab Infrastructure // 2.0

  • Building a production-style homelab to practice infrastructure security, automation, and observability at scale.
  • Using Ubuntu Server 24.04 LTS with Ansible for configuration management and Docker Compose as the current container layer, with K3s planned later.
  • Planning a secrets workflow with HashiCorp Vault and SOPS, plus Prometheus/Grafana monitoring and Loki logging.
  • Documenting hardware, build decisions, and architecture choices as the system evolves, with GitHub Actions planned through a self-hosted runner.

Homelab Infrastructure // 1.0

  • Built and self-hosted a personal cloud environment on a headless Ubuntu Server node using Docker and Portainer.
  • Configured secure remote access through Cloudflare Tunnels and Tailscale to work around CGNAT restrictions without port forwarding.
  • Ran live services including a Python Telegram automation bot, algorithmic trading workloads, and the Server HQ monitoring dashboard.
  • Retired this iteration after documenting the lessons that informed the current infrastructure rebuild.

Set_Forgor

  • Built a set-and-forget Expert Advisor in MQL5 for MetaTrader 5, designed around XAUUSD with a 1:3 risk-reward ratio.
  • Entry signals align an H1 200 EMA trend filter with M5 RSI crossback confirmation and an ATR volatility gate.
  • Trade management handles 40-pip break-even moves, optional risk-free pyramiding, cooldowns, and per-direction re-entry locks.
  • Includes a custom on-chart GUI panel for live state monitoring.

CutMyHair

  • Led a team and designed the architecture for a cross-platform barber booking app with mobile and web interfaces.
  • Designed a multi-role NoSQL schema optimized for real-time state sync and low-latency document reads.

Web Trainer Assistant / Quality Assurance Tester Intern

Kidocode Sdn. Bhd.

  • Guided students through live coding sessions on the Cubie platform, debugging logic errors and explaining programming concepts in real time.
  • Performed pre-release manual QA on unreleased Cubie Tasks and logged bugs and regressions into a shared tracking sheet.

I build things that run quietly in the background. I got into tech because I genuinely enjoy figuring out how things work under the hood, and that is still what drives me. My work sits between infrastructure, automation, and backend systems, with a constant search for the next thing to build or break.
