Senior react native developer + swiftUI
Poland · 5 years of experience · Upper-Intermediate ·Published today
Poland · 5 years of experience · Upper-Intermediate ·Published today
Position: React Native Developer
Duration: around 2 years.
Description: I am currently a key contributor to an IoT application designed for plant cultivation, boasting an impressive user base of over 10,000 active users. In this role, I have leveraged a diverse range of cutting-edge technologies to ensure the application's success, including React Native, Redux Toolkit, Swift, Kotlin, TypeScript, WiFi and Bluetooth SDKs, Auth0, CodePush, Appcenter CI/CD, Bitrise CI/CD, Bugsnag, Firebase services, and push notifications.
Third Company - Mobile Application Development
Position: React Native Developer
Duration: 1 year.
Description: During my time at this company, I had the opportunity to create a variety of mobile applications from the ground up. My portfolio included e-Commerce, IoT, gamification, and augmented reality apps. Technologies I proficiently utilized encompassed React Native, TypeScript, Redux (Thunk), Redux Persist, REST API, Material UI, WebView, Geo-location services, and native modules for both iOS and Android platforms. Additionally, I implemented push notification functionality.
Second Company - IoT Mobile Application Development
Position: React Native Developer
Duration: 1 year.
Description: At my previous role, I focused on developing an IoT mobile application. My responsibilities included using React Native, TypeScript, Redux (Thunk), Redux Persist, REST API, Material UI, WebView, and native modules for iOS and Android platforms. I also incorporated geo-location services to enhance the application's functionality.
First Company - Mobile and Web CRM Systems Development
Position: React & React Native Developer
Duration: 1 year.
Description: In my initial role, I was involved in the creation of mobile and web-based CRM systems for private companies. Collaborating with a talented team, I effectively employed technologies such as React, React Native, Redux (Saga), NativeBase, REST API, charts, and Material UI to deliver comprehensive solutions.
Freelance - Web Development and Design
Duration: 1 year.
Description: During my freelance endeavors, I specialized in creating admin panels for existing websites and developing engaging landing pages. I demonstrated proficiency in HTML, CSS, ES6 JavaScript, Bootstrap, and Material UI to deliver tailored web solutions.
IoT Plant Management: I spearheaded the development of an IoT-based application that revolutionized plant care. This innovative solution allowed users to monitor and manage the conditions of their gardens and indoor spaces in real-time.
Sensor Integration: I played a pivotal role in integrating sensors into the application, enabling users to access crucial environmental data such as temperature and air humidity. This data was collected from sensors placed within the garden or indoor area.
Remote Control: Users could remotely control various aspects of their gardens through the app, including turning on heating, watering, lighting, fogging, and ventilation systems. This feature provided a seamless and convenient way to ensure optimal plant growth.
Customized Scheduling: I implemented a scheduling feature that allowed users to create custom queues for specific actions, such as controlling the duration of lighting or water pumps. For instance, users could set the lights to operate from 1 a.m to 3 a.m and then disable them, only to be reactivated from 6 a.m to 8 a.m.
Enhanced User Experience: My contributions significantly enhanced the user experience, making it easy for individuals to nurture their plants with precision and care. The intuitive interface and real-time data access made plant management both efficient and enjoyable.
Positive User Feedback: The success of this project was reflected in the positive feedback from users who found value in the application's capabilities. The IoT plant management app garnered a loyal user base and contributed to its recognition as an innovative and user-friendly solution.
This project exemplifies my ability to tackle complex challenges, develop intuitive user interfaces, and leverage IoT technology to create practical solutions. It was a rewarding experience that reinforced my commitment to delivering high-quality software that makes a meaningful impact.
Collaborative Environment: I value teamwork and open communication. I am looking for a workplace where collaboration is encouraged, and knowledge sharing is actively promoted. I believe that collective creativity often leads to the best results.
Continuous Learning: The tech industry evolves rapidly, and I am committed to staying current with the latest developments. I expect my employer to support my professional growth through training, workshops, and access to resources.
Clear Goals and Expectations: I appreciate clear project goals and well-defined expectations. A structured work environment helps me deliver quality work efficiently.
Flexibility and Innovation: I believe in embracing new technologies and approaches. I would like to work in a company that is open to exploring innovative solutions and adapting to industry trends.
I am excited about the prospect of joining a dynamic team where I can contribute my skills and experience to create outstanding React Native applications.
