About
Hello, I am Mel
LeadWin System is my personal technology brand. I work on IT administration and on software built with AI-assisted workflows, and I like systems that are easy to reason about, easy to recover and honest about their limits.
This site is a portfolio of that thinking. I do not list employers, job titles, years or metrics here. Instead, each case study shows the problem, the architecture, the decisions and the safety notes, and every technology is labelled by how much evidence there is behind it.
Interests
What I care about
01
IT administration
Keeping accounts, access and integrations in a known, documented state.
02
AI-assisted development
Using coding agents as tools, with approvals and limits that I can explain.
03
Systems architecture
Drawing the boundaries first: what talks to what, and what must never.
04
Automation
Small automations that are observable, restartable and easy to switch off.
05
Infrastructure
Hardened services, scripted installs, atomic releases and rollbacks.
06
Application engineering
Typed, tested apps on mobile, desktop and the web.
07
Security-conscious development
Remove capabilities before guarding them. Keep secrets out of repositories.
08
Problem solving
Find the likely cause first, change one thing, and prove the result.
How I work
A few habits
- Prove it works. A change is done when a test or a check says so.
- Smallest effective change. Less to review, less to roll back.
- Write the rollback first. Then make the change.
- Say what is not claimed. Evidence status beats a long list of logos.
