Software for the work you shouldn't be doing by hand.

Using AI-assisted development, I build custom tools, automation, and data pipelines that take the repetitive busywork off your team's plate, so it stops eating their week.

// why now

Custom software used to be a big-company luxury. That just changed.

Building software around how your business actually works used to mean months of effort and a five-figure budget, so most small and mid-sized businesses made do with spreadsheets and off-the-shelf tools that didn't quite fit. AI-assisted development has changed that. The tools alone aren't the whole story, though. Combined with ten years of engineering experience and the judgment to know what to build and how to build it well, they let me deliver the same quality of custom software in a fraction of the time it used to take, at a price that makes sense for a business your size.

The same quality of work, at a price a small business can actually afford.

// what I build

Four ways I get time back for your business.

automate

Kill the repetitive work

Scheduled jobs, data scraping, and automated reports that replace the weekly copy-paste-and-format ritual with something that runs itself.

connect

Make your tools talk

Get data out of spreadsheets, accounting software, and the apps that don't sync, and into one place you can actually use and trust.

data

Turn your data into answers

Make the data you already have easy to use, with clean dashboards and plain-language reports that answer the questions you keep asking, instead of digging through spreadsheets to find out.

build

Tools that fit how you work

Custom internal apps built around your real workflow, for the parts of the job no off-the-shelf product quite handles.

// often asked for Web apps & internal UIs Live data monitoring Process optimization Route & scheduling planning Lead-generation tooling Automated reporting Custom dashboards System integrations
// how it works

Clear scope, fixed price, and I'm still around afterward.

We talk

A short call to find the single most expensive repetitive thing you or your team does.

Fixed scope

One clear deliverable at one agreed price, so you know the cost before any work starts.

I build & hand off

Working software, documented plainly, set up so your team can actually use it.

Ongoing support

I'm still here when the business changes and the tool needs to change with it.

What this looks like in practice.

Days → minutes

A California environmental-consulting firm was spending days each month pulling species data and assembling compliance reports by hand. I built a pipeline that gathers the data automatically and drafts the reports, turning a multi-day grind into a few minutes of review.

// who you'd be working with

Hi, I'm Grayson Walker.

Grayson Walker, software and data engineer based in San Diego

I'm a software and data engineer with ten years of experience building production systems. That ranges from petabyte-scale data pipelines and live data-monitoring tools that run every day without anyone watching them, to the web apps, internal tools, and user interfaces a business runs on. I take on a small number of independent clients where I can build something that actually gets used, rather than another dashboard nobody opens.

You work with me directly. No account managers, no handing the job to a junior. The same person who scopes the work builds it and supports it.

// questions

Good things to ask before we talk.

What kind of businesses do you work with?+
Small and mid-sized businesses in San Diego, across just about any industry. Usually ones where a real chunk of someone's week disappears into manual, repetitive work in spreadsheets or disconnected apps.
What if I'm not sure software is even the answer?+
That's exactly what the first call is for. Sometimes the right answer is a small tool, sometimes it's a better use of software you already pay for, and sometimes it's not worth building at all. I'll tell you honestly which one it is.
What does a project cost?+
It depends on scope. For a defined project I quote a price up front after a short discovery call, so you know the number before work starts. Ongoing support and smaller, ad-hoc tasks can be billed hourly or on a simple monthly retainer.
Isn't custom software too expensive for a small business?+
It used to be. Building bespoke tools meant months of work and a five-figure budget. AI-assisted development has changed that, so I can build the same quality of custom software in a fraction of the time, at a price that makes sense for a small or mid-sized business. For a lot of companies, custom-fit software is affordable for the first time.
How long does a project take?+
Most first projects are scoped to land in a few weeks. The discovery call is where we agree on a timeline you can count on.
Do you offer ongoing support after it's built?+
Yes. Software needs to change as the business does, so most clients keep me on a light monthly retainer for updates, fixes, and the next thing on the list.
Are you local to San Diego?+
Yes. I'm based in San Diego and happy to meet in person, which is part of why I work mostly with businesses in the area. I can also work fully remotely when that's easier.
