Mobile App Excellence

We Keep Your Apps Running

Started in 2019 when a Bangkok-based developer noticed too many businesses struggling with app maintenance. Five years later, we're still fixing bugs at 2am and actually enjoying it.

What Got Us Here

Most app development shops want to build new things and move on. We found ourselves drawn to the opposite—the ongoing work that keeps apps alive and users happy.

There's something satisfying about tracking down that crash that only happens on certain Android devices, or optimizing an API call that's been slowing down checkout for months. It's not glamorous work, but it matters.

Our team grew from those late-night debugging sessions and early morning hotfixes. Now we handle support for apps across healthcare, retail, and logistics—all from our Bangkok office where we can actually talk to clients in real time.

How We Actually Work

These aren't aspirational values we put on the wall. They're habits we developed because they made our work better.

Response Time Matters

When your app crashes, waiting 24 hours for a response isn't helpful. We built a rotation system so someone knowledgeable sees your message within two hours, even on weekends.

Actual Root Causes

Quick patches feel good but often hide bigger problems. We dig into logs, reproduce issues, and track down what's really causing trouble—even when it takes longer.

Clear Communication

You shouldn't need a CS degree to understand what's wrong with your app. We explain technical issues in plain language and show you exactly what we're planning to fix.

Who's Behind the Updates

Small team, deliberately. Everyone here writes code, tests features, and talks to clients. No endless layers between you and the person fixing your app.

Linnea Vesterholm

Technical Operations Lead

Spent seven years at a logistics startup before joining us in 2021. She's the one who built our monitoring system that catches most crashes before users report them.

Linnea handles our most complex debugging work—the kind where the stack trace makes no sense and the issue only appears under specific load conditions. She also trains new team members on our support workflow.

Outside work, she volunteers teaching basic coding to high school students around Bangkok. Says it helps her remember what it's like to see code for the first time.

Our Support Process

Nothing revolutionary here. Just a system we refined over hundreds of support requests.

1

Initial Assessment

We look at your issue, reproduce it if possible, and give you a realistic timeline—usually within a few hours of your first message.

2

Testing and Fix

Changes go through our staging environment first. We test across devices and OS versions before touching production.

3

Deployment and Monitor

After deployment, we watch error rates and user reports for 48 hours to make sure the fix actually worked.
