Senior Java Developer (Real Estate)
POLAND
ABOUT THE PROJECT
Within this project, you will be working on an IoT platform for a real estate company. The idea of this product is to make smart, highly available, and fault-tolerant AWS-based solutions for managing thermostats, smart locks, and other equipment in our client’s apartments, and to make it easy to use. Our globally distributed teams are working on an event-driven system that will allow direct monitoring and control of devices located in apartments in the United States. On the Klika Tech side, we are responsible for the system’s end-to-end behavior, including front-end, back-end, and mobile applications.
Our Smart Home technology solutions have positively impacted the following areas:
- Environmental Sustainability: By incorporating energy-efficient technologies and optimizing energy and water usage, we contribute to reducing carbon footprint and promoting environmental sustainability.
- Safety and Accessibility: Features like smart locks, security cameras, and smoke detectors connected to centralized monitoring systems enhance the safety and security of residents, helping to prevent accidents and unauthorized access. Many smart locks allow doors to be unlocked without the use of physical keys, which makes it more convenient to access apartments and avoid losing keys.
- Quality of Life and Inclusivity: Smart apartment solutions can be designed with accessibility in mind, ensuring that features are user-friendly and accommodating for residents with diverse needs, particularly for individuals with disabilities or mobility issues.
- Smart Cities Initiatives: By developing solutions that align with smart city initiatives, we contribute to global urban sustainability goals. Smart apartment technologies can integrate with city-wide systems for energy and resource management, waste reduction, and transportation, supporting broader efforts to create more sustainable and livable urban environments.
