Lee Li Xiong (Matt Leon) · 李立雄

DevOps & Site Reliability Engineer — AI Automation Builder & Vibe Coder

I turn manual ops busywork into AI-driven pipelines — from infrastructure monitoring to cost accountability — and ship side projects (SaaS, games) just because I like exploring new tech.

  • 3+ yrs DevOps/SRE
  • AI-automated reporting pipelines
  • 4 shipped mobile games
  • Worked across Malaysia, Germany, Switzerland & the Netherlands
Why hire me

01 — The short version

Why hire me

Four things I'd want to know if I were hiring me.

AI-Powered Ops Automation

Built and maintain multiple AI-driven cron jobs at Beyondsoft: a Daily Status report, a CPU Usage report, and a CDN Network Traffic report — turning raw infrastructure data into scheduled, readable insights with zero manual effort.

AI Cost Accountability

Own the AI Model Billing pipeline: a weekly automated cron job that pulls usage data via the provider's billing API and reports which AI model and which team is driving the most cost — giving leadership a clear, recurring cost breakdown.

Production DevOps at Scale

3+ years at Bosch automating CI/CD, quality gates, and observability (Elasticsearch/Logstash) across multiple cross-country projects, including ASPICE-audited workflows.

Ships Real Products

Co-developed and published multiple mobile games on Google Play under Mattleon Labs / NX Publisher, alongside AI-assisted side projects — a builder who explores new tech for fun, not just on the clock.
