The client was a company that owned multiple home appliance brands. The framework's purpose was to define all the common functionalities and ensure that the mobile applications used were strictly aligned with the predefined requirements.

Among many others, the main goals of the framework were to:
• Provide it as a white-label product.
• Implement a highly configurable platform to serve any specific brand.
• Have built-in third-party integrations.
• Fully develop all the common business requirements.
• Define modular design and components.
• Minimize all resource usage, including battery, CPU, storage size, and network.
• Ensure user-friendly experiences across all functionalities.

I contributed to all the framework modules on multiple layers, including networking, local storage, data caching, data processing, notifications, and several applications built on top of it.

A free taxi application with hundreds of thousands of users on the platform enables clients to order a taxi ride to their desired destination. Users could choose to be picked up from a location and have the taxi rider take them wherever they wanted to go by paying with cash, or they could enter a destination address and easily reach it by paying with cash, a card, or a corporate voucher. They could even chat with their driver and receive live notifications with the status of their ongoing ride.

My main goal was to completely refactor the app codebase to include reactive concepts and to apply the MVVM pattern fully, highly increasing the code quality and the overall app stability. I implemented a reactive component to communicate with the platform servers using an MQTT-based third-party library. I also continuously oversaw the app issues and crashes and provided quick and reliable fixes to increase the app's stability. I continued adding new features to the current application flows that enriched the user experience.

A free taxi application that holds the largest number of available drivers. Also, the sole application that has been integrated with the Romanian taxi drivers' taximeter fiscal device, namely Equinox. The app enabled a safe and controlled system when engaging in the taxi ordering process between a client and an authorized taxi driver.

Acted as the sole developer that developed the application using the MVVM pattern, a custom reactive component built on top of a third-party MQTT library, and a custom library created for the company's needs. I actively engaged in the UI/UX, defining the flow and providing valuable feedback to improve the client-driver interaction further. I defined logical schemas for the overall application flows and implemented them accordingly using clean reactive architecture.

A free-to-use SwiftUI-based application that offered users video conferencing functionalities. Users can attend video conferences, chat with other participants, join separate breakout room calls, and view incoming broadcasts and screen shares from other participants.

I fully developed specific functionalities from the app, including the chat and the separate breakout room. I continued verifying known app issues and crashes to provide stable fixes while providing general app maintenance.

I worked with a team of two developers on an application meant for people who wished to book an appointment at any available location: restaurants, barbershops, beauty salons, and taverns.

Business owners could add their location, set the availability, mention their available services, add their staff among their availability, and appear in user's searches. Staff members could also access the business they belonged to and manage their appointments.

Users could set up their accounts based on their location preferences. They could book available slots for existing services.

I worked on every application part, including the base architecture, custom components, server communication, data storage, notifications, and the UI/UX design.

A team of two developers developed an application that provided most of the required functionalities for minor and major beekeeping activities.

I implemented most of the project's structural architecture, using the MVVM design pattern and UI layout, using custom components among all the functional requirements. Everything was implemented using reactive extensions to ensure proper UI updates based on user input and actions.

I developed the app in two versions, a lite version with a limited amount of data that could be stored and processed and a pro version with no limitations.

Various graphs were available that used the user input data as entry points.

The user data was stored offline in an SQLite database for which I implemented a general-purpose query creation mechanism for basic and complex CRUD operations.

I implemented data exports that were available as printable files or as CSV documents.

I worked with another developer on an application that provided the basic reminder functionality with an enhanced and highly customizable set up flow that significantly increased its utility and usability. The application would provide local notifications whenever and however the user configured them.

Users could set up custom events that would trigger as reminders, providing notifications at the desired date or an interval defined by their custom recurrence.

The application offered a custom UI set up that enabled users to define specific running times or recurring variations for reminders.

The application offered a multi-theme UI design.

The user could even change UI components and layouts based on personal time preferences and set up default predefined time intervals for a quick reminder creation.
