Victor F.

Mobile App developer in Japan (UTC-7)

I specialize in mobile application development, focusing on both iOS and Android platforms. My primary languages of expertise include Dart with Flutter for cross-platform development and Swift for iOS-specific projects. Over the years, I've contributed to the developer community by creating several packages, which are freely available on Flutter's package repository. Moreover, I'm proud to have two applications currently live on the Apple Store, a testament to my dedication and proficiency in crafting user-friendly and innovative mobile experiences. In my current role at a startup, I wear multiple hats, contributing to both backend and frontend development efforts. On the backend side, I've honed my skills in deploying cloud-based solutions using Google Cloud Platform, leveraging technologies such as Node.js, GraphQL, and PostgreSQL to build robust and scalable systems. Meanwhile, on the frontend, I've been utilizing Flutter extensively, taking charge of code reviews and ensuring the quality and efficiency of our applications through rigorous testing methodologies. One aspect of my work that I find particularly rewarding is integrating essential features like payment gateways using tools like RevenueCat for subscription management, implementing in-app purchases, and incorporating AdMob for monetization strategies. I'm deeply passionate about continuous learning and strive to stay updated with the latest advancements in technology. I'm always eager to enhance my skill set and take on new challenges that come my way.
