Three things, done properly.

Not a menu of everything I can do — the three I keep getting hired for. Each one has a real example behind it, not a buzzword list.

01 ongoing

Email deliverability & inbox infrastructure

  • Build and operate live email platforms end-to-end
  • Recover blacklisted IPs and warm them back to inbox
  • DKIM / SPF / DMARC setup, feedback loops, suppression hygiene
  • Sender reputation monitoring + reactive fixing when it tanks
real example

Mailgreet — a live email platform I built and operate. Deliverability isn't a one-time setup; it's a 2am pager when a blackhole lists your IP.

02 project / ongoing

API tooling & backend systems

  • Design and ship REST APIs that survive real traffic
  • Trigger-routing systems that tie services together without duct tape
  • Rate limiting, auth, caching, observability from day one
  • Developer-facing tooling that other engineers actually want to use
real example

ProWebLook — 12 API tools shipped and running, DA 12. One of them is a trigger-routing system that took a sprawling webhook mess and turned it into one predictable pipeline.

03 project

Production firefighting & scale

  • Disk-full at 2am, OOM kills, runaway queues — diagnosed and stopped
  • Laravel / MySQL at scale: slow queries, index debt, locking drama
  • Build pipeline unbreaking: Vite + Composer resolving cleanly
  • Post-mortems that actually prevent the next incident
real example

The disk crisis: production filled up overnight, writes were failing, alerts were screaming. Root-caused it, freed the space, stopped the bleed, then fixed the actual leak so it never came back.

> not sure which bucket you're in? that's fine.
