Scarlett A. Scott · Senior Software & DevOps Engineer
Systems that hold under pressure.Built light enough to adapt.
I'm Scarlett, a senior engineer with 13+ years building payment rails, aerospace ground systems for the U.S. Space Force, and the cloud infrastructure underneath them. I own systems end to end, from the NACHA file to the Kubernetes cluster, and I leave every codebase better than I found it.

// About
Engineer. Team lead. Systems owner.
I'm a multidisciplinary senior engineer with 13+ years across aerospace, fintech and enterprise B2B platforms. I've been the sole architect of a production ACH platform, built orchestration for an aerospace missile-warning ground system for the U.S. Space Force, and run the AWS and Kubernetes infrastructure those kinds of systems depend on.
I like the niche, oddball problems and the hard, unglamorous parts: debugging production at 2 a.m., getting a NACHA file byte-perfect, passing the pen test, writing the runbook. I lead from inside the code and I bring the whole team along.
How I got into engineering
“I eavesdropped on a computer science class, and not even ten minutes in I knew I loved it and wanted to work with software for the rest of my life. And that has never changed for even a second.”
Why a dragonflyA dragonfly is an engineering problem solved well. Four independently driven wings on a lattice of veins: stiff where it needs strength, flexible where it needs to bend. It hovers, reverses and changes direction mid-flight without losing control. That's the standard I hold my systems to: structured enough to be reliable, light enough to adapt.
// How I work
Principles I build and lead by.
Technical skill gets a system shipped. These are what keep it running, and keep the team that runs it intact.
Leave it better than you found it
Every touch is an improvement.
Every PR, runbook and handoff should leave the system easier to run than it was before. I fix the flaky test I tripped over, write the doc I wish I'd had, and pay down the debt next to the feature.
No one left behind
Teams ship, not heroes.
I lead by pairing, reviewing generously and sharing context, so the whole team can own production, not just the person who wrote it.
Lead by example
I won't ask for what I don't do.
I lead from inside the code. I take the 2 a.m. page, write the tests, document the fix and do the unglamorous work I'd ask of anyone on the team. Standards stick when the person setting them meets them first.
Resilience
Built to take a hit and keep flying.
Retries, idempotency, graceful degradation and clear failure recovery are designed in from day one, whether it's an aerospace missile-warning pipeline or a payout run.
Reliability
Boring in production is the goal.
Money and mission data don't get a second try. I build observable, audited, tested systems that do the same correct thing every time, then I own them on call.
Light on my feet
Rust to React, NACHA to Kubernetes.
I move between the frontend, backend, infrastructure and compliance without losing pace, and pick up a new stack when the problem calls for it.
See the whole system
No silos. No one in the dark.
I'm a big-picture engineer. Before I build, I need to know who uses the product, what they need and how they'll interact with it, and how every part fits together: not just the services, but the servers and network it runs on, how it's operated, and the people involved. Specialists are valuable; silos aren't. You can't build a good system without understanding the end users and how everything interacts, and people don't do their best work in the dark.

TweakTags
Live
Self-hosted inline CMS for Next.js, React and plain HTML.
Bolt a CMS onto a site you already have instead of rebuilding the site around one. Put a data-tweaktags-* attribute on any element, sign in, flip on edit mode and change text, rich text, images and video right on the live page. Content saves to your own database and every visitor sees the saved version, with no rebuild and no redeploy. Under the hood it's a framework-agnostic browser engine, pluggable database and auth adapters, and a security model built like a payments system: rotating refresh tokens, CSRF protection and server-enforced roles.
Private, self-hosted home security with facial recognition.
