Your business runs on manual work. It doesn't have to.

I build custom software and automation tools for small businesses in New Hampshire — so you can stop managing spreadsheets and start running your business.

Sound familiar?

  • You're tracking jobs, clients, or inventory in spreadsheets that break every other week.

  • Your quoting process takes hours when it should take minutes.

  • You're paying for multiple tools that still don't talk to each other.

  • Your team spends half the day on work that should happen automatically.

Manual processes made sense when you were starting out. Now they're holding you back.

What I Build

Business Automation

Eliminate the repetitive manual work. Automated workflows that run in the background — data entry, notifications, reporting, approvals — without you touching them.

Custom Internal Tools

Dashboards, scheduling systems, and internal apps built around your exact workflow. Not a generic SaaS product with features you don't need. Something that fits.

Integrated Websites

A website that's actually connected to your business — quotes, bookings, client portals, and forms that feed directly into your systems.

What this looks like in practice

1

Contractor quoting

Enter a job scope, get a professional quote generated and emailed automatically.

2

Scheduling systems

Client books online, job appears in your calendar, crew gets notified, invoice goes out when it's done.

3

Client portals

Give customers a login to track their project, upload documents, and approve work.

4

Reporting dashboards

See your business numbers in one place, updated in real time, without pulling from five different places.

5

Form → database automation

Intake forms that automatically create records, trigger follow-ups, and notify the right people.

Sean Duggan

Who's behind this

I'm Sean Duggan — a software engineer based in Southern New Hampshire.

My background is in enterprise software: cloud systems, automation, AI, and building things that actually work under pressure. I've spent years solving complex technical problems for large organizations. Now I apply that same approach to small businesses.

I work directly with owners, not through layers of project managers. You talk to the person building your software.

I'm local — based in the Derry/Londonderry area — and I work with businesses across NH and Greater Boston, in-person or remote.

Let's talk about your workflow

No pitch. No commitment. Just a conversation about where your business is losing time and whether software can fix it.
