Portfolio

Candidus

Candidus serves as an IoT device integrated within greenhouses, functioning as a central system that autonomously optimizes crop growth. Through the utilization of advanced sensors, it effectively collects environmental data. Employing its proprietary algorithm, Candidus determines the precise timing to regulate lighting conditions, based on variables such as existing light intensity, crop type, and the grower's desired objectives, encompassing growth and flourishing, among others.

Olivia AI

I contributed to the development of a personal finance native application crafted for Android and iOS platforms, incorporating a robust back-end infrastructure utilizing Node.js. Throughout the project, I actively participated in feature development and undertook all necessary steps, skillfully employing Kotlin for Android Native development, Swift 3 for iOS Native development, and implementing back-end microservices along with REST APIs in Node.js.

Test Automation Platform for Mobile Apps

A Ruby-based test automation platform designed for conducting black-box testing on pre-compiled mobile applications for Android and iOS. The applications can be developed using Java, Kotlin, Objective-C, Swift, or Unity. Leveraging Appium and Selenium WebDriver, this test platform seamlessly creates human-readable layers of test tools for test automation experts. Moreover, it facilitates the generation of comprehensive test reports in various formats including HTML, PDF, JSON, and XML, accompanied by screenshots for enhanced understanding of test issues. Additionally, the platform offers backdoor libraries for Unity using C#, for Android using Java, and for iOS using Swift, enabling their integration into the development version of the app under examination. These backdoors grant access to public methods within the app, effectively establishing a gateway in the test device, allowing external consumers within the same network to utilize these methods.

Gemain

I implemented the front-end of the website utilizing jQuery, constructed the client's portal using AngularJS, and developed the backend as a REST API utilizing C#. Although the company has ceased operations, a preview of the website is still operational.
