Petros

Experienced Apple Swift Engineer specializing in building fast, intuitive apps across iOS, macOS, and the wider Apple ecosystem.

I build Apple-platform products that feel fast, clear, and dependable, with a strong focus on real user needs, maintainable code, and polished execution. At Plum Fintech, I work in the Engagement Team on high-impact initiatives across end-to-end flows, Stonefruit, and Plum's core iOS app, helping ship features that support hundreds of thousands of people in managing and growing their money more intelligently. My day-to-day work is centered on Swift, SwiftUI, UIKit, and architecture that fits the product and team best, including TCA, MVVM, MVP, VIPER, and pragmatic MVC or hybrid approaches when they make the most sense. I care a lot about building modular, testable systems that can move quickly without becoming fragile, and I work closely with product, design, backend, and data teams to make sure technical decisions stay aligned with both user experience and business goals. Alongside my professional work, I created PromptBar, a lightweight macOS menu bar app built in SwiftUI that gives quick access to multiple AI chats in one focused workspace. I hold an Integrated Master's in Informatics and Computer Engineering, along with Full Stack and iOS Development certifications, and I bring an ownership mindset to everything I build, from architecture and code quality to delivery, collaboration, and long-term product stability.

June 2023 - July 2025

Self-Employed

iOS Engineer

  • I began my time at AppArt focusing on building robust, efficient code for the My DEDDiE App, using Swift and the latest iOS frameworks to deliver a smooth, reliable user experience. As the project evolved, I took on broader responsibilities, guiding development processes, mentoring engineers, and ensuring that technical decisions aligned with best practices and the long-term goals of the product.
  • My work included driving key architectural decisions to ensure the app remained performant, maintainable, and scalable. I collaborated closely with cross-functional teams - including product managers, designers, and backend engineers - to translate requirements into clear technical specifications. I also designed and implemented new features, optimized performance through targeted refactoring, and resolved critical issues, all while maintaining GDPR compliance and meeting the demands of a highly regulated environment. Mentoring developers and conducting thorough code reviews was also a key part of my role, ensuring code quality and consistency across the team.
  • One of my most significant contributions was the HEDNO Pioneers Green Energy Awareness project. I led the iOS implementation of this major sustainability feature, which allows users to track real-time renewable energy production from solar, wind, hydro, biomass, and other RES sources. Users can select specific geographical areas and timeframes for analysis, and view carbon reduction metrics in a clear, user-friendly interface. This update positioned the My DEDDiE App as a leader in environmental awareness and digital innovation, making green energy data easily accessible to citizens across Greece.
