Hire the Best Travel Planners
in Ireland

I believe language is a very powerful tool and can be used strategically. I have a journalistic background (graduate of the prestigious Reportage Institute in Poland) so my writing tends to be well-researched, with attention to detail. I specialize in travel writing and scuba diving. I have been a digital nomad for the past 13 years. Thanks to that I can think outside the box and provide unique content with a multicultural background. On top of that I have international experience in management positions in events and wellness fields. I am certified in Digital Communications, Transmedia Storytelling For Global Audiences and Creative Economy. I look forward to hearing from you to further discuss the skills and talent I can bring to your projects. Yours Sincerely, Katrina

React Native and Flutter developer with 50+ production iOS and Android apps shipped. Core stack: Firebase, REST APIs, TypeScript, Dart, payments, push notifications, real-time data, offline sync, and App Store/Google Play releases. 𝟓𝟎+ 𝐀𝐏𝐏𝐒 𝐒𝐇𝐈𝐏𝐏𝐄𝐃 | 𝟐𝟓𝟎𝐊+ 𝐃𝐎𝐖𝐍𝐋𝐎𝐀𝐃𝐒 | 𝟗𝟗%+ 𝐂𝐑𝐀𝐒𝐇-𝐅𝐑𝐄𝐄 𝐌𝐎𝐁𝐈𝐋𝐄 𝐀𝐏𝐏𝐒 𝐅𝐀𝐈𝐋 𝐁𝐄𝐘𝐎𝐍𝐃 𝐓𝐇𝐄 𝐔𝐈 Most mobile app problems start below the screens: weak state management, fragile Firebase architecture, inconsistent API handling, unreliable payment flows, missing edge cases, and release planning left too late. My work focuses on preventing those problems in new React Native and Flutter builds, and fixing them properly in unstable iOS and Android products. 𝐍𝐄𝐖 𝐑𝐄𝐀𝐂𝐓 𝐍𝐀𝐓𝐈𝐕𝐄 & 𝐅𝐋𝐔𝐓𝐓𝐄𝐑 𝐀𝐏𝐏𝐒 Before development scales, I define the parts that become expensive to change later: • User flows and application state • Data models and API contracts • Authentication and role handling • Firebase or backend architecture • Payment and subscription logic • Push notification workflows • Offline and weak-network behavior • Analytics, crash reporting, and release planning The result is a first version built for real users, not a prototype that needs to be rewritten after launch. 𝐀𝐏𝐏 𝐑𝐄𝐒𝐂𝐔𝐄 & 𝐒𝐓𝐀𝐁𝐈𝐋𝐈𝐙𝐀𝐓𝐈𝐎𝐍 For a slow, crashing, unfinished, or difficult-to-maintain app, I review the underlying system before adding more features. The audit covers: • React Native or Flutter architecture • Dependencies, SDKs, and build issues • Crash logs and performance bottlenecks • Firebase Auth, Firestore, Storage, and Cloud Functions • REST API failures and inconsistent data handling • State management and navigation problems • Stripe, Apple Pay, Google Pay, and in-app purchases • Push notification delivery • App Store and Google Play release risks • Real-device testing gaps across iOS and Android The goal is not to patch one visible bug while leaving the real cause untouched.
