Sean Dinwiddie

Enterprise engineering, without the enterprise headcount

Senior architecture, delivery, and modernization for organizations whose systems have outgrown the team maintaining them. You get one accountable engineer with decades of full-stack depth, not a rotating bench.

When this is the right call

Nobody wants to touch it

A system that works but nobody wants to touch, and every change takes longer than the last.

The migration that never starts

A migration that has been proposed twice and never started, because the risk was never scoped.

No one owns the shape

A team that can ship features but has no one to own architecture, review, and the long-term shape.

Spend up, speed down

Software spend that keeps rising while the thing it pays for gets slower.

What the engagement covers

Architecture and modernization

System design, incremental migration paths off legacy stacks, and the written trade-offs behind each decision, so the reasoning survives after the engagement ends.

Delivery

Hands-on implementation in TypeScript, React, Redux Toolkit, Node, and Rust, with tests, review, and CI that the existing team can keep running.

Automation at scale

Integration work across the systems already in place, aimed at the recurring cost of manual process rather than at replacing what works.

Technical leadership

Fractional CTO cover: hiring input, architecture review, and a senior voice in the room when the decision is expensive to reverse.

How it starts

No proposal deck, no discovery phase you pay for twice.

1

A strategy call

The system as it stands, and what it is costing you now.

2

A written assessment

What is load-bearing, what is at risk, and what the first three months should address.

3

Your call

That assessment stands on its own — you can act on it with your own team if that turns out to be the right answer.

Start with the assessment, not the contract.

One accountable engineer, and a written read on your system you can act on either way.

Smaller than this?

Local shops, restaurants, trucks, and kiosks are served by the sister practice, Sean Dinwiddie’s Webmastery, which covers websites, local search, and right-sized automation for small business in Klamath Falls and Redding.
