Gerard Gargan

Software Developer

I build web apps and business automations for small companies who've outgrown spreadsheets.

About Me

Running a business means wearing a lot of hats — and too often, time gets swallowed up by admin, manual processes, and systems that don't talk to each other.

I help small businesses and SMEs turn those time-draining, error-prone processes into software that just works. Whether it's automating a booking system, building an app your team can use from day one, or connecting systems that currently rely on someone copying data between spreadsheets — I'll work with you to understand the problem, build the right solution, and make sure it delivers real results.

Before moving into software engineering, I spent years in operations and senior management at a global manufacturer. I've sat in the meetings, managed the teams, and dealt with the same inefficiencies that most businesses live with. That experience means I don't just build software — I understand how businesses actually run, and I know how to build solutions that fit the way your team works.

Real Problems I've Solved

SopPro

SOP Management Mobile App

Most businesses still create standard operating procedures in Word or Excel — formatting is inconsistent, version control is manual, and getting approvals means chasing people over email. Worse, the people who know the job best often aren't the ones writing the SOPs, because the software gets in their way.

I built a user-friendly mobile app that lets teams create SOPs at the point of use, with AI-assisted drafting, built-in approval workflows, automatic version control, and one-tap PDF export in a standardised layout.

Kev-In — Personal Project

A fun personal project built around Christmas — a web app that lets you upload a photo, pick your favourite Christmas movie, and get a custom poster starring yourself, generated by AI in real time. It got a lot of traction while it was live, with users sharing their generated posters across LinkedIn and social media.
