Experience
Messaging Application
This project included three different chat clients and a distributed server using customers' networking devices. Chat clients were a web application with React, Redux, and JavaScript, a desktop application with Java, and a mobile application with Android programming language.
I owned the back end of the project and the web-based client as the front end. I used the Openfire project for the back-end part and customized it to create a distributed server.

Network Analyzer
This project, developed to analyze the network data between computers, consisted of two products. One of them is the "reporting product" used for collecting, parsing, and saving the necessary information from the network data. The second one is "monitoring product," used to process various analyses with the collected data from the nodes.
I owned the "monitoring product" of the project. The tech stack of the product included ElasticSearch, Kibana, React, Redux, Electron, Node.js, Python, C#, and Java.

Ambulance Billing System
This project is a MERN stack-based web application for the usage of ambulances, billing companies, and insurance companies. The main aim of this project was to handle patient, insurance, claims, and payment data with a user-friendly and easy-to-use application.
The developed system was integrated into insurance companies' platforms to send the patient claims and receive payments from the company.
In this project, I designed the overall architecture of the software and compliance with the NEMSIS data schema.

Mobile Plugin Architecture
I created Android programming language-based mobile application and a software development kit to integrate different applications implemented with SDK usage.
In this project, I designed a plugin architecture and implemented an SDK to integrate various features developed by different teams in a single mobile application. With this project, the customer easily added new features to their system.
The SDK could transfer location, health, target, video, and sound data between plugins and the main application. Also, plugins can easily add their other features to the main application with the help of the SDK.
