We rescue dying software and build what's next

904 Software rescues fragile apps, modernizes aging systems, and builds new software from scratch. Direct access to the engineer doing the work. No offshore handoffs. No layers.

Get a Diagnosis

20+ years in production systems. iOS, Android, web, and backend. Based in Jacksonville, FL.

For companies whose software is unstable, outdated, or nonexistent — we fix what's broken and build what's missing.

What We Do

Rescue. Build. Maintain.

Whether your software is drowning or doesn't exist yet — we get it to shore. We diagnose what's failing, stabilize what's critical, and build what's missing. No six-month discovery process. Just practical engineering.

🏊

App Rescue

Your application is down, unstable, or stuck in a failed release. We assess the situation quickly, identify root causes, and restore stability — so your team and your users aren't waiting on a months-long engagement to see results.

🔨

New Builds

Need something built from scratch? Mobile apps, web platforms, APIs, internal tools. We take your idea from first commit to production — with the same senior-level attention we bring to rescue work.

↻

Legacy Modernization

Old codebase. Outdated frameworks. No one left who understands how it works. We modernize legacy systems in controlled phases — upgrading what matters, preserving what still works, and reducing risk at every step.

📱

Mobile — iOS & Android

Apps that crash, lag, drain battery, or can't pass App Store review. We resolve platform-specific issues, improve performance, and bring your mobile application back to production quality. Or build it from day one.

🌐

Web Applications

Slow page loads. Broken workflows. A frontend no one wants to touch. We clean up web applications so they're faster, more reliable, and actually maintainable by your team going forward.

⚙

API & Backend

Flaky integrations. Timeout errors. A backend that everyone's afraid to change. We fix the systems underneath your application — so your data flows, your services stay up, and your team can ship without fear.

Why 904 Software

Senior engineering & architecture. No layers between you and the work.

You're not hiring an agency with account managers and a revolving cast of junior developers. You're working with a senior engineer who designs the solution, writes the code, and owns the outcome.

Direct Access

You talk to the engineer who architects the solution, writes the code, and pushes the deploy. No project-manager theater. No communication layers.

Architecture to Implementation

System design, technical strategy, and hands-on engineering. Mobile, web, APIs, databases — from high-level architecture down to the code that ships.

No Offshore Handoffs

Every line of code is written here. No overnight surprises from a team you've never met. No subcontractors in another timezone.

Practical, Not Reckless

We don't propose six-figure rewrites when a targeted fix will do. Stabilize first. Improve in phases. Keep the business running.

Best Fit

This is for you if...

Your application is unstable or unreliable in production
Your codebase is old, fragile, or poorly documented
Your previous developer or dev team is gone
Your releases are painful, slow, or blocked
Your mobile app has performance, crash, or App Store issues
Your backend or API layer is causing downstream problems
You inherited software you didn't build and don't fully understand
You need a senior engineer to assess the situation and start fixing it
You have an idea for a new app or internal tool and need someone to build it right the first time

Whether your software needs saving or doesn't exist yet — we can help. Rescue, new builds, or both.

About

Who's doing the work

Atlantic Beach Ocean Rescue

Jamie McLaughlin

Founder · Principal Engineer & Architect

I've spent over twenty years building and fixing technology — from enterprise network infrastructure to production mobile apps and backend systems. I've managed large-scale IT projects and shipped software in operational and regulated environments where things have to work.

Before I was rescuing software, I was a lifeguard with Atlantic Beach Ocean Rescue. I still race Ironman-distance triathlons — 140.6 miles where the only way to the finish line is through the problems in front of you. That mindset carries into everything I do: assess the situation, commit to a plan, and don't stop until it's done.

I started 904 Software because too many businesses get stuck with fragile software and no one reliable to fix it. Dev shops overpromise. Freelancers disappear. Agencies add layers. I wanted to offer something simpler: a senior engineer who looks at your code, gives you an honest assessment, and does the work.

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