LeadWin System / personal technology portfolio
IT administration, automation and AI-assisted engineering
I am Mel. This is where I document the tools I build and the systems I keep running, with the safety controls and trade-offs left in rather than polished away.

01 / Focus
What I work on
IT administration
Keeping systems, access and integrations running, with scripted installs, recorded state and a written way back.
Systems & InfrastructureAutomation
Small, observable automations: feed polling, bots, scheduled jobs, dry-run first, with a kill switch.
Baguio Outage RadarAI-assisted engineering
AI agents as working tools inside strict, reviewable boundaries: read-only by default, hash-bound approvals.
BROSystems integration
Connecting public data, messaging and local runtimes through narrow, well-tested interfaces.
VideoLab
02 / Case studies
Featured projects
Five sanitized case studies. All sources are private, so each one shows architecture, decisions and safety notes instead of code.
Personal AI operations assistant
BRO
A desktop assistant that drives an AI coding agent CLI as a local runtime. It is read-only by default, and any write needs a human approval that is bound to the exact change by a hash.

Programmatic video pipeline (evaluation)
VideoLab
A local-first, scriptable video editing pipeline: transcript and scene analysis, a reviewable edit list, captions, animated overlays, GPU rendering and automated quality checks.

Telegram alert bot with staged rollout

Operations practice case study
Systems & Infrastructure
How I approach running software: hardened services, scripted installs, rollback-first change management and quiet, useful alerting. Qualitative, drawn from the other projects.
