Vetted App registrations developer in the United States (UTC-4)

Hi! I'm Pazia, I'm a software engineer specializing in mobile applications & I'd love to share my passion & knowledge of computer science with you. I received my bachelors degree in computer science from Brown University, where I graduated magna cum laude in 2020. After graduating, I spent 4 years working as a software engineer at Google, working on a variety of projects including Google Docs, Sheets, & Slides on iOS. During my time at Google, I also conducted SWE interviews, mentored software engineering apprentices on my team, helped CS students prepare for coding interviews and volunteered at student events and workshops. I am passionate about sharing my knowledge & experience & helping other folks in their own coding journeys. In particular, it's really important to me to help folks who hold marginalized identities, i.e. women, non-binary folks, LGTBQ+ & BIPOC folks, feel better entering the world of tech. As a multiracial female/non-binary SWE, I know how intimidating the tech industry can be especially when you don't see people around that look like you and I want to help you feel more confident in this space :) Looking forward to meeting & working with you!

Ioannis K.

Vetted App registrations developer in Greece (UTC+2)

With almost a **decade** of dedicated experience in Mobile Development, I am a self-disciplined professional who thrives on taking projects from **concept to deployment**. Here’s what defines my approach: 1. **End-to-End Ownership**:I don’t just write code; I architect solutions. From initial wireframes to the final app release, I take full responsibility. My commitment extends beyond development — I support the whole lifecycle of the app, meaning I take care of the **CI/CD pipelines, analytics** for the app, **crash-reports** to keep the app health optimate, taking care of **user-feedback** (in-app or through the stores), as well as **patching the app** from critical issues through the store or as over-the-air updates outside of it. 2. **Architectural Excellence**: As a team lead, I’ve championed robust architectures. I believe in **future-proofing** our apps, emphasizing maintainability and scalability. Good practices aren’t just guidelines; they’re my compass for long-term success. 3. **Technical Proficiency:** While my primary focus has consistently been on **React Native** app development, I’ve also delved into native code for building essential modules. Over the past decade, I’ve honed my skills in **Objective-C**, **Java**, and lately **Swift and Kotlin**. My adaptability across these languages ensures a well-rounded skill set for comprehensive mobile solutions. 4. **Collaboration and Mentorship:** I cultivate a collaborative environment, guiding junior developers and collaborating closely with stakeholders. In summary, I offer a blend of technical prowess, leadership, and unwavering commitment. Let’s build something remarkable together! 🚀
