Software Developer

Making great products is what development is all about. As an app developer, I use the right tool for the right job. Swift, UIKit, SwiftUI, Obj-C, or literally anything else. It is about getting things done the best way possible, especially when I have to learn a new tool to do it. I believe organization is essential towards that goal, that is why I take meticulous notes of requirements through checklists to make sure that nothing slips through the cracks.

Full-Stack FinTech iOS App Development

GameFi

I contributed to the development of the iOS app in Swift and SwiftUI, as well as Node.js for the financial backend. I wrote REST APIs and used the APIs of multiple financial services like Plaid and Sila, and other services like PlayFab. The database was Google Firestore Database. The Node.js server using Express.js was deployed on Heroku servers.

iOS App Developer

Freelancer

I developed in Swift & SwiftUI an App Store app called "Twinkly: Christmas Cards". I used Apple's AR Kit to add effects like stars and twinkles on pictures. The effects can be edited, moved, rotated, erased and replaced by other effects after taking the picture or by importing a picture from the photos app.

Interests

Apart from being a developer, I love learning languages. To learn a new language I use language learning apps, I listen to music and podcasts, watch videos and movies, all in the target language.

I spend most of my free time with friends and family, whether it's going for a hike, palying video games or just having dinner. I love sight seeing in historical places, especially if accompanied by a curious and imaginative partner. Oh, almost forgot, I'm always down for a football match
