Guten Morgen zusammen! 🇩🇪☕

Time for notes before the workshop. I came with two projects: #ZarazJade, where I want to polish the map and sheet presentation at once. 🗺️

The other, if it makes sense, leaves me 16 days to finish it. A belated #Shipaton... 🤪

It's been a crazy busy week. 💪

Burned through a ton of tokens on a new feature for #ZarazJade. Can't wait to show what it does - just need time... and data... ⏳

Didn't have time for #Shipaton this year, but next year I want to take part - it's great to be part of that energy! 🚀

My first #Mac mini from 2009 is retiring too - well deserved. It sent almost 2 million notifications and synced dozens of terabytes of data. 🖥️

Carried it to school for presentations, and for the last 7 years it ran #ZarazJade. 🎒

Time to finally put it to rest. 🙏 #DevDiary

I admit, a bit of sadness crept in. I wrote this backend back when we romantically cared about every single line of code. 💭

Built the whole thing in #Nova, over many months. 🛠️

But pragmatism wins. Backup done, database dumped. Shutting down #ZarazJade v3. 🔌

#DevDiary

Today's the day - cutting off the old #ZarazJade backend. Migrated almost 1,800 accounts, 99% of users. 🚀

The rewrite was needed because the old service couldn't support multiple cities in the app. 🏙️

Not a blocker anymore, but I need to free up resources to build more. 🔧 #DevDiary

Before setting a shutdown date for the legacy backend, I checked where my users actually were. 🔍

#ZarazJade was initially built for iOS 26, but it quickly turned out I had to go "a year lower" - which let me keep more users. 📱

#DevDiary

The #ZarazJade migration itself went super fast - the lines crossed after a few days, but the tail dragged on for weeks. 📈

I sped things up with a pop-up about the update. Every app should be able to show a message from its backend! 💬

Now, I have even more than 💯 !
#DevDiary

It's been over 60 days since the #ZarazJade 4.0 update. 🎉

Over several months I rewrote the entire backend, which forced a migration of existing users. A delicate process, so I wanted to handle it deliberately. 🧭

@claudeai prepared reports for me along the way. 📊
#DevDiary

I'm working on an improved Feedback feature in #ZarazJade - a direct line to users. 🗣️

Those two one-star reviews still cross my mind - could've caught them earlier if feedback was easier to give. 💬

Another feature needs time to mature, so there's room for this indulgence. 😉

In the first few weeks after the update, #ZarazJade got two one-star reviews. ⭐

The #AppStore lets you reply to reviews, which gives you a direct line to the user. I fixed the bugs, got a thank-you in return. 🙏

So version 4.1 now has Feedback built right in - reachable from anywhere. 💬

Another challenge in #ZarazJade was migrating from the old #database to the new one.

At its peak, I had ~30k users, but many dropped off while the old version went unmaintained. 📉

Losing the most loyal ones stung the most, which is why I check the migration progress report every single day. 🔍

A month since #ZarazJade hit prod - it's been a tough road, and the last few days proved it can break anywhere. 😅

Public transport is incredibly tough because of the sheer volume and quality of the data - but I want to do this right. 🎯

I had to build in some safety nets. 🛡️

They say the best #mobile apps are born from a moment of need. #ZarazJade was exactly that kind of story. 📖

Back in 2018, heading home from work on the last day before the holidays... of course three buses in a row just didn't show up. 😤
