The problem

Large enterprise network operations (Telefonica Spain, General Electric) were running on manual workflows — costly, error-prone, slow.

Approach

  • Identified highest-leverage manual workflows; automated them end-to-end.
  • Applied Six Sigma to measure, reduce variance, and lock in gains.
  • Shipped internal web apps to expose automation to ops teams.

Key decisions

Automate the boring parts first

Repetitive high-volume tasks have the fastest ROI. Glamour comes later.

Trade-offs

  • Process rigour slows initial rollout — pays back many times over.

Impact

  • $100K+ annual operational savings; measurable reduction in manual effort.
  • Foundation for a career in systems at scale.
Let's build

Have a system that needs to scale — or stop breaking?

I work with a small number of teams each month on architecture reviews, scaling, and hands-on backend engineering. If that sounds like you, let's talk.
