Vetted Core Data developer in Romania (UTC+2)
I am Vlad, an iOS engineer with five years of experience. During my career, I had the chance to work on projects ranging from small ones to corporate-level projects. In this period, I experienced multiple architectures, design patterns, Apple frameworks, Clean code principles, SOLID principles, understood the value of testing and the benefits the TDD approach can bring to your design. I consider these skills fundamental to writing easy-to-change code. The primary trait of good architecture and good code, from my perspective, is the possibility to update and refactor code smoothly. At the end of the day, these are all skills that can be taught and acquired. I am more than happy to share them with you, the mentee. My ultimate goal is to help everyone write better code and incorporate these principles in day-to-day coding. If this sounds like a person you would like to collaborate with, don't hesitate to contact me!
Vetted Core Data developer in Japan (UTC+9)
**iOS Developer with experience at Apple and at Wells Fargo. Have app HarmonyCalc on the App Store. Background in music and editorial.** At Apple, I grew as a developer and leader. There, I worked on a relatively large codebase that contained legacy Objective-C, AppKit with Swift, and SwiftUI code. The numerous different kinds of fixes and additional features I implemented on this app made me confident in being able to solve any technical issue within my domain. My leadership skills also improved, as I had the opportunity to help onboard new team members, document the app’s architecture in detail, and help manage the project on which I worked. Working on my project at Apple, I was able to finish new features ahead of schedule that worked flawlessly and were covered by unit tests. I helped team mates become unblocked and complete tasks faster. At Wells Fargo, part of my role included researching and implementing new technologies, and my work in this helped lead to a US Patent submission. At TruU, I built a whole new logging module that was used to report the majority of new bugs. My co-workers have praised my technical competence, ability to learn quickly, and willingness to receive feedback graciously.
