Freelancing Experience

Worked on routing data from gateway to cloud and on-premises via MQTT and gRPC.
Worked on the remote software updates, and network optimization based on addresses.
Worked in embedded Linux development using Yocto for service network configuration.
Worked on gateway development for sensor data extraction with protocols such as 6LoWPAN and MIOTY.
Worked on the microservices part of the embedded team, comprising two services that emulate AWS IoT Core.
Worked on an data transmission engine for handling data between the gateway to the cloud and on premises brokers.

Integrated new devices and sensors into the network.
Optimized the network based on addresses, achieving a significant speedup.
Improved data representation for flexibility for both the cloud team and on-premises clients.

Conducted an investigation for the gateway from the conceptualization of the product to the production line.
Developed a flexible way to build and distribute the gateways as well as internal service orchestration.
Developed software for the gateway that interacts with inverters for power plants and energy farms.
Developed internal tools such as a Modbus simulator and test clients for local development.
Integrated various inverters and meters via Modbus TCP/IP to communicate with the gateway.
Developed metrics and request/response schemes with the backend via MQTT on AWS.

Developed a product from the concept stage to the production line.
Provided real-time metrics and request/responses for the first power plant.
Enabled remote data as metrics from the devices to the cloud in a unified form.
The presentation occurred at the company's first power plant and received positive feedback.
Delivered a secure product that was cost-effective to produce, easy to maintain and extend, and met all requirements.
