Rescue. Modernize. Keep it running.

904 Software helps companies fix systems that have gotten scary to deploy, hard to operate, or fast to write and slow to trust. AI-assisted, senior-led.

Most companies are caught between two failure modes.

The old systems are slowing them down. Deploys are scary, the codebase is haunted, the team is afraid to touch the parts that work.

The new systems are getting written faster than anyone can review them. AI tools made shipping cheap. They did not make software easier to operate, debug, or hand off.

Both produce the same problem. Software nobody on the team really understands.

Work that needs an experienced engineer in the room.

No six-month discovery. No recommendation deck. The fix.

App Rescue

The product is in production and something is wrong. Performance, reliability, security, deploys, data integrity. We find the actual cause and fix it. Not a roadmap. Not a recommendation deck. The fix.

Legacy Modernization

Old stack, new requirements. We migrate in slices, with the system staying live. We do not rewrite from scratch unless rewriting is genuinely cheaper than fixing. It rarely is.

🔍

Production Debugging

Slow queries, mystery 500s, mobile apps that crash on a specific carrier in a specific city. The unglamorous diagnostic work most teams cannot afford to staff full time.

🔨

AI-Assisted Build-Outs

Net new features and small products. We use modern AI tooling aggressively, then review, test, and structure the output like real engineering. You get the speed without piling up debt the next team has to live with.

Mobile, Web & Backend

iOS and Android, web frontends, APIs, databases. Production problems do not respect those boundaries, so we do not either.

No layers between you and the work.

You talk to the engineer who does the work.

No account manager between you and the codebase. No offshore relay. No junior consultant rebadged as a solutions architect. When you describe the problem, the person hearing it is the one who will be in the codebase that afternoon.

Decisions get explained, not hidden.

Every change comes with a reason a human can defend. If we use AI tooling to move faster, we still own the result, read the diff, and stand behind the deploy. You should never look at part of your own system and feel like a tenant in it.

We finish things.

Discovery is short. Scope is specific. The work either ships, or you get a clear answer about why it should not.

Use the tools. Ship faster. Keep humans in the loop.

AI tooling is real. We use it every day.

It is serious leverage in the right hands. It also makes weak engineering invisible until production, when the team that owns the code cannot explain what it does or why.

The wave hitting most companies right now is not a productivity boom. It is a generation of software written faster than anyone can review. Clean on the surface, fragile underneath, and surprisingly hard to maintain.

Our position is simple. Use the tools. Ship faster. But ship code your team can still operate, architectures a human can still picture, and systems you can hand to the next engineer without an apology.

The future is fewer systems, built better. Not more systems, built faster, until everyone is afraid to touch them.

Who's doing the work

Jamie McLaughlin

Founder · Principal Engineer & Architect

904 Software is run by a working engineer, not a sales team.

The name is from Jacksonville. The frame is from the beach. Lifeguards with Atlantic Beach Ocean Rescue are calm because they have done the rescue many times. They watch the water before anything goes wrong, and when something does, they move fast and bring people back.

That is the operating posture here. Years inside production systems, on the bad nights as well as the good ones. Shipping under deadline, debugging under pressure, rebuilding the parts of systems nobody else wanted to touch.

The new tools change the speed. They do not change the job.

Based in Neptune Beach, FL. Working with companies across Northeast Florida and remotely nationwide.

Tell us what is broken.

A few paragraphs about the problem is enough. You will hear back from the engineer who would actually do the work, usually within a day. If we are the right fit, we scope it together. If not, we say so. No deck. No discovery package.
