As the product owner and lead developer, I developed an AI-powered recipe application to assist users in meal planning by providing macronutrient estimations based on preferences and dietary goals. My responsibilities included brainstorming use cases, setting priorities, engaging with potential customers, and crafting detailed specifications. I researched AI capabilities, defined the architecture, implemented core functionalities, and built the MVP. Additionally, I led the beta launch, formulated a business strategy, and collaborated on a design approach to ensure the app was user-friendly and aligned with market needs.

Worked on a fintech app aimed at Arabic-speaking countries, where I focused on implementing right-to-left (RTL) layouts, localizations, and specific design adaptations required for the MENA market. This involved customizing UI components to meet regional standards, handling sensitive transaction data, emphasizing secure integrations, and maintaining consistent device performance. The project provided valuable experience adapting fintech solutions for unique cultural and linguistic needs.

Built a synchronized content display system using Swift and SwiftUI for both iOS and macOS platforms. The project used the MultiConnectivity Framework to synchronize real-time content across devices, allowing remote control and presentation on large wall displays. My role included coordinating with another iOS developer, managing data synchronization between devices, and implementing a framework that enabled remote control and seamless data sharing for dynamic presentations.

In this project, I developed a robust iPad application for sales representatives, allowing them to view, filter, sort, and group extensive datasets to streamline their sales presentations and analysis. The app incorporated a detailed map view to highlight regional sales data and enabled sales teams to interact with data in a highly visual and organized manner. My role included designing the architecture to handle large volumes of data efficiently, implementing complex data handling features such as filtering, sorting, and grouping, and ensuring smooth performance on iPad devices. The app’s usability and responsiveness were key, as it was designed for field use, often in data-limited environments.

Via Transilvanica is a specialized hiking app covering extensive trails throughout Romania, divided into seven unique tracks with milestones and key points of interest for hikers. As the lead developer, I coordinated a team of volunteers, recruiting junior developers and ensuring the app’s timely feature completion. I was responsible for designing offline functionality for uninterrupted use in remote areas, implementing a detailed map view to display tracks and landmarks, and tailoring UI elements to show relevant information for each location type, such as contact details for hotels and emergency services. I developed an issue-reporting tool that allows hikers to document track problems with images. Additionally, I contributed to brainstorming sessions with the client to ideate impactful features, bringing insights into app architecture and usability. I also guided junior team members in clean code practices and architectural principles, enhancing app quality and development efficiency.

An Objective-C app modernized with Swift, having a big codebase and a large development team involved. It enables monitoring and controlling of 200+ devices in users' houses by creating automations, like setting a thermostat graph, creating events as triggers (e.g., user location, window, door sensor, smoke detector), and alarm system.

TECHNICAL RESPONSIBILITIES:
• Implementing new features while improving the existing codebase
• Developing and executing refactoring strategies in the long term
• Participating in leadership weekly meetings, where we discussed the development challenges and improvements for the future
• Articulating with different teams to merge and develop co-dependent features
• Performing regular code reviews

A Swift-based app developed on iOS and Android. I was the tech lead, and my responsibilities involved consulting the client on the technical limitations of iOS and helping create an application for purchasing internet data plans for flights using a credit card or PayPal and applying voucher codes. The payment method needed to be stored when users intended to for easy payment on the next flight.

The app was supported by a back-end solution handling the API and configuration of the flight router, including a safelist of domains, secure storage of users' payment data, and the creation of an authentication system and an API for the mobile. My role was to articulate with the back-end team throughout the process and ensure the iOS and Android apps would have an interface to communicate and implement back-end communication in the app.

An Objective-C app for accessible communication with friends when looking for answers or recommendations, like selecting a movie for a romantic dinner.
Friends were limited to the user's contact list and encouraged to add only close friends to the list on the app. These friends could forward questions to one of their friends to get help answering them, but it would be blocked from further forwarding. I was the project's technical leader in a team of two iOS developers and two Android developers.
