Software Built From the Inside Out

Good business software starts with the people who use it every day. I work with end users, trace the real workflows, and understand how each part of the organization connects before designing the tools that support it.

HOW IT WORKS

A sane way to get help.

No mystery work and no pressure. You get a diagnosis, a clear explanation, and a straightforward path forward.

01 / START HERE

Tell me what’s happening.

Send a note about the device, the problem, and when it started. “It’s just weird” is a perfectly valid opening statement.

02 / DIAGNOSE

I trace the cause.

I look past the symptom to find the actual fault instead of throwing random fixes at the wall.

03 / EXPLAIN

You get clear options.

I explain what I found in normal language, what matters, and what the fix involves before moving ahead.

04 / RESOLVE

Get it sorted.

The goal is a computer that works properly—and a clear answer you can trust when the job is done.

READY WHEN YOU ARE

Something not working right?
Let’s get to the bottom of it.

ABOUT

One person.
One bench.

401comp is a one-person shop. It started with a two-year Computer Information Systems degree from New England Institute of Technology, where peer-tutoring coursework turned into a teaching offer at graduation — a new job's timing meant taking a different path instead.

From there came programmer/analyst work on healthcare systems, including MUMPS, and later a small business fixing other people's Windows machines.

401comp is independent computer service built around diagnosis first—not guessing, upselling, or throwing software at a problem until it shuts up. The goal is simple: find what’s actually wrong, fix it properly, and leave you with a clear answer and a product you can trust.
