We've spent the last three years helping apps stay current, reliable, and responsive to what users actually need. Each project here represents months of careful work—debugging issues that seemed impossible, optimizing performance that was dragging teams down, and building update pipelines that just work.
Start Your Project
The notification system was failing during peak hours. We rebuilt the entire queue management from scratch—not a small task, but the alternative was losing customers. Now it handles 50,000 daily alerts without breaking a sweat.
Android & iOS
Double-bookings were causing real problems for clinics. The sync logic needed complete rethinking. Took us five weeks to get it right, but appointments haven't conflicted since February 2025.
Cross-Platform
Their payment system worked fine until it didn't. Black Friday 2024 showed exactly where the weaknesses were. We spent December completely overhauling how transactions get processed and verified. The 2025 holiday season was smooth sailing.
High VolumeMost projects start with something not working quite right. Maybe crashes are creeping up, or performance is slower than it used to be. Sometimes it's bigger—a feature that needs complete rebuilding because requirements changed.
We dig into the codebase first. No assumptions, no quick fixes that'll cause problems later. Once we understand what's happening (and why), we map out the actual work needed. Then we do it, test it thoroughly, and make sure your team knows exactly what changed.
The boring truth? Good app maintenance is methodical. It's about catching problems before users do, keeping dependencies current, and making sure updates don't break things that were working fine.
Every app is different, but here's what most support engagements look like from our side. This isn't marketing fluff—it's literally how we structure the work.
We review your codebase, check error logs, and talk with your team about pain points. No sales pitch here—just figuring out what's actually wrong and whether we're the right fit to fix it.
Once we know what needs fixing, we map out the approach. This includes priority ranking (some things can wait, others can't), timeline estimates, and identifying any risks we see coming.
The actual work happens here. We code, test, retest, and keep your team updated weekly. If we hit unexpected complications (and we usually do), we adjust the plan rather than pushing through blindly.
Updates roll out gradually—we're not gambling with your entire user base. We watch error rates closely for two weeks after launch, ready to roll back if something unexpected surfaces.
"HubPortalConnect took over maintenance on an app that three previous contractors couldn't stabilize. They spent the first two weeks just understanding the architecture before touching anything. That patience paid off—we haven't had a critical bug in six months."
