Travis Sutphin

Principal engineer, 25+ years building software — eight of them owning a P&L across three departments. I'm the person founders call when a technical decision is about to get expensive.

My background What I've built ↗

An engineer who's owned a P&L.

Most people who can evaluate your architecture have never owned a budget. Most people who can read a P&L can't read the code. I spent eight years as Director of Development and Operations with profit-and-loss responsibility across three departments, after fifteen years writing the software.

That is the whole difference. When I tell you a rebuild is the wrong call, I am not making an engineering argument — I am telling you what it does to your operating costs, your hiring plan, and your next eighteen months. I have had to live with that answer from the other side of the table.

What I get called for

Some engagements are one of these; most are several at once.

Architecture & system design

Deciding how a system is put together before it is expensive to change. Data model, service boundaries, what to build and what to buy.

Technical due diligence

Reading a codebase, a team, or a vendor proposal and telling you what is actually there. Useful before an acquisition, a contract, or a rebuild.

Legacy modernization

Taking a system that still works but has run out of room, and moving it forward without stopping the business that depends on it.

Full-stack delivery

Writing the code, not just the strategy deck. Multi-tenant SaaS, internal tools, APIs, auth, the parts that are tedious and matter.

Cost & operations

What a technical decision does to headcount, hosting spend, and the operating model. The part most technical advice leaves out.

AI-augmented development

Using AI as production tooling under engineering discipline, rather than as a demo. Where it earns its place, and where it does not.

“Our old system did the job but it had hit a wall. We couldn't grow it, and we couldn't hand it to customers. Travis took the whole thing on himself, reframed it around how we actually think about our sites, and had a modern, self-service platform live in under four months with all of our data moved over.”
Joel Deis, Owner, Ridgeline Engineering

Three calls I've made, and what happened →

The work happens at AIwhirks

This site is about me. AIwhirks is my software studio, and it is where every engagement — advisory or build — actually starts.

AIwhirks is an AI-augmented software studio building and maintaining custom web applications for businesses that have outgrown off-the-shelf tools. Based in St. Augustine, Florida. I do the work.

I also build and run my own product, so I know both sides of the buy-or-build question: simpleWhirks, a suite of business apps on one login. Books (bookkeeping) and Proposals (quotes through to invoices) are live, with more on the way.

Advisory

Fractional CTO and technical leadership. Architecture ownership, vendor and team evaluation, and being the person who says no while it is still cheap to change course.

Build

Custom web applications, legacy modernization, stalled-project rescue, and ongoing development on a monthly retainer.

Frequently Asked Questions

Who is Travis Sutphin?

A principal engineer with 25+ years building software, eight of them as Director of Development and Operations with P&L responsibility across three departments. The combination is the point: most people who can evaluate an architecture have never owned a budget, and most people who can read a P&L can't read the code. Work runs through AIwhirks, his software studio in St. Augustine, Florida.

What does a fractional CTO actually do?

Technical leadership without a full-time hire: owning the architecture, evaluating vendors and agencies, shaping the roadmap, sitting in on engineering hires, and reviewing code nobody else on your side can review. Companies use it when technical decisions have outgrown the founder but the workload doesn't yet justify a full-time CTO salary. Advisory engagements run through AIwhirks.

What is AIwhirks, and how does it relate to this site?

AIwhirks is an AI-augmented software studio building and maintaining custom web applications for businesses that have outgrown off-the-shelf tools. This site is the personal one — who I am, what I've built, and what I think. Every engagement, advisory or build, starts at AIwhirks. I do the work either way.

How can I see Travis Sutphin's work?

The work is documented as case studies on AIwhirks — legacy modernization, multi-tenant SaaS, and platform builds, with the technical decisions written up. The blog is where the reasoning behind the work gets worked out.
