A B2B platform for company communication, featuring CRM and chat modules. I built the microservices with Node.js and the front end with React and React Native. The platform was deployed with Kubernetes, and it uses REST and WebSockets for communication.

A time-tracking app for organizations, built with NestJS, React, and React Native. I developed this app with many features, such as real-time data updates via sockets, various approval workflows, calculations, and a very generic way to represent the company structure.

I made improvements to the React Native application architecture to reach performance goals. My work included introducing an optimized FlatList and a Redux store, preloading videos, and using covers for a better user experience. I also rewrote the app navigation.

During the fintech product's development, I carefully considered the end users' needs and aimed to create a highly secure, usable, and performant platform. To achieve this, I built a React front end that is intuitive and easy to use, guaranteeing a seamless and enjoyable user experience. Additionally, I implemented a Node.js back end that is highly scalable and reliable, ensuring the application runs smoothly at all times.

Both MongoDB and MySQL databases were used to store and manage data efficiently, enabling the application to handle large volumes of data without compromising performance.

Building an iOS application for a men's magazine was an exciting and challenging project. As a developer, I aimed to create a dynamic and visually appealing application that engages readers and provides them with an exceptional user experience.

To achieve this, I utilized the latest iOS development tools and technologies, including Swift, Xcode, and the Cocoa Touch framework. I created a well-designed and responsive user interface, integrating features such as push notifications, in-app purchases, and social media sharing.

In addition to creating a visually appealing app, I prioritized performance and optimized the application for speed and reliability. This involved paying careful attention to back-end functionalities, including data storage, retrieval, and analysis.

Ultimately, I was able to create an application that resonates with the target audience and enhances their reading experience. I achieved this by integrating rich multimedia content, interactive features, and seamless navigation. This well-crafted and aesthetically pleasing application makes readers feel engaged, informed, and inspired to read more.

As a developer, I created a city guide mobile application for Fattal Leonardo Hotels, using React Native for the front end and Yii2 PHP for the back end. The app provides hotel guests information about tourist attractions, local events, and dining options, enhancing their travel experience.

I collaborated closely with the Fattal Leonardo Hotels team to understand their requirements and incorporated their feedback throughout the development process. I also ensured the application was user-friendly and easy to navigate, with a visually appealing interface.

To support the back end, I implemented a Yii2 PHP-based REST API to provide the mobile application with real-time data, ensuring easily accessible and up-to-date information on local attractions, events, and dining options.

Overall, the city guide application was a great success and served as a valuable tool for enhancing their guests' travel experiences. It was a pleasure to work on this project and contribute to the success of Fattal Leonardo Hotels.

As a Flutter developer, I worked on a digital waiter app for a restaurant, allowing customers to easily browse menus, order food, and pay their bills using their smartphones.

The app is integrated with the restaurant's existing POS system and provides real-time updates on order status. It also includes features like customizing orders, tracking order history, and leaving feedback. The Flutter framework allowed for fast development and a seamless user experience across both Android and iOS devices.

This project involved providing architectural consultation focused on improving performance for Ituloh, Indonesia's number one commerce video app. As a React Native architect, I introduced optimized components such as FlatList and implemented improvements to the Redux store. I also recommended the preloading of videos and the use of covers for a better user experience. Through these efforts, we achieved the desired performance goals and delivered a better experience for the app's users.

Worked on a React Native mobile application in the healthcare sector. Was working on the in-app browser integration, a lot on the native bridge, and shared web-native functionality. Worked on increasing the performance and usability of the app.

I helped develop several mobile apps for Heidelberg Materials. Working in a team on B2B mobile applications that helped customers execute complex construction/manufacturing processes and communicate.
