Empowering Teams with Custom Apps and Training
Let’s be honest – sometimes your tools just don’t do what you need them to. That’s where we come in. We build custom apps, clever scripts, and AI-powered features for Jira, Confluence, and the whole Google toolstack. Whether it’s automating the boring stuff, fixing annoying gaps, or making your tools talk to each other – we’ve got your back. And if you’d rather build things yourself? We’ll show you how. With practical training in Atlassian Forge, you’ll be creating your own magic in no time. Here’s what we do (and do well):
- Custom apps, scripts & solutions for Atlassian Jira, Confluence, and Google Toolstack
- AI features that actually help
- AppSheet & Apps Script development (from quick fixes to full-on apps)
- Trainings that don’t put you to sleep
- Real support from real people – no buzzword bingo
No corporate jargon. No overcomplicated solutions. Just smart stuff that works – built around what your team actually needs.
Got a tricky workflow or tool problem? Let’s fix it together. Get in touch and tell us what’s been bugging you – we’re all ears.
Atlassian Development
Jira and Confluence are powerful, but they don’t always do exactly what your team needs. We build custom apps and features that close those gaps – whether you’re tackling specific use cases or looking to replace outdated scripting-based apps with cleaner, more maintainable Forge solutions built to last.
We’re at the forefront of Atlassian Forge development, creating secure apps using the most modern and trusted framework in the Atlassian ecosystem.
Atlassian Migrations
Whether you’re leaving outdated systems behind or bringing scattered tools together, we make your transition to Jira and Confluence simple and stress-free.
We handle the entire migration process – from moving your data and workflows to setting up your Atlassian Cloud environment just the way you need it. With our experience, you get a clean start without losing what matters.
Seamless, reliable, and fully taken care of – so your team can get back to work, fast.
Atlassian Forge Training
In this hands-on workshop, your team will learn how to develop custom apps for Jira and Confluence using Atlassian Forge – the most modern and secure way to build in the Atlassian ecosystem.
We tailor the training to your needs, guide you through setup, and work with you to build a working app prototype. Along the way, you’ll get a clean, ready-to-use base you can continue developing – plus plenty of time for questions and deep dives.
Whether you’re just starting out or looking to expand your skills, we’ll help you build the foundation to create tools your team will actually use.
Google Cloud Development
We build custom tools on Google Cloud to make everyday work easier. That might be a simple app to manage approvals, a script that updates spreadsheets automatically, or a system that connects different tools so your team doesn’t have to do things twice.
We work with Google Apps Script, AppSheet, and the broader Google Workspace stack to create solutions that fit your workflow. Whether it’s a quick fix or a more complex tool, we focus on building something that’s practical, reliable, and made to last.
