Developed satellite acquisition and tracking software for use with in-house motorized antennas.

Drove deployment and managed the Astranis' first carrier monitoring networks in North America and the Phillipines providing end-to-end monitoring capabilities.

Built a satellite payload simulator to enable firmware and flight computer testing.

Supported in orbit testing activities.

Orchestrated a $Xm white-label partnership with Siemens through close collaboration with their European and China based teams

Led the product launch of the AwairNet mesh adapter across US, European, Canadian, and Australian regions, achieving a 50-60% reduction in installation costs and contributing to a 25% additional increase in Awair’s revenue within 6 months, restrained by manufacturing bandwidth

Engaged customers through interviews to define the product vision, features, and releases. Findings were prioritized, developed into requirements, and buy-in obtained from the c-level executive team

Directed a 7-person cross-functional engineering team located in South Korea and introduced the sprint process to streamline product development

Collaborated with key partners such as Armstrong Ceilings and a leading US-based international financial institution to drive 7-figure business growth. Direct impact on roadmap - released new dashboard analytical tools to meet partner needs

Goal was to present solutions to help solve the problem of upfront installation costs faced by Awair's enterprise clients when looking to install their Air Quality Monitors. The cost of devices can be only 40-50% of the total cost

Prototyped and technically evaluated three different technical solutions. Results were presented to C-level executive team

For communication, used technologies such as Lora, Thread and ZigBee in both 2.4GHz and sub-1GHz bands. Developed IP-level connectivity over embedded MCU's using IP64 / IP46 and NAPT technologies. Used embedded C, C++, (on ARM Cortex and ESP32) with bus-level protocols such as I2C/SPI/UART for sensor and IP-level communication

Debugged multi-node, distributed wireless systems using both IP-based and proprietary communication protocols. Built an internal tool for monitor of and debugging of multiple devices at the same time.

Spearheaded the idea of a model for mesh components to enable fast product release cycles, reducing development of each by over $15k

Authored comprehensive handover documentation / presentations to engineering team

Patent holder #63417689 on UX flow / mechanism for onboarding of mesh devices

Developed and maintained Awair's Smart Plugs and Indoor Air Quality sensors. Played a pivotal role in the successful release of the Glow C Smart Plug.

Wrote firmware in C, C++, with use of Python/Java for automated testing. Firmware used FreeRTOS, ThreadX as RTOS of choice, but had exposure to bare-metal programming as well. Used WiFi, BLE, and Ethernet for connectivity and protocols such as MQTT, CoAP, and HTTPS for commands and sensor data transmission. Worked with bus-level protocols such as UART, I2C, SPI, for communication with onboard sensors.

Architected an innovative PPP IP link between the Awair Omni and Surface Mount, enabling full internet connectivity through the Surface Mount's Ethernet port. Implemented NAPT on the Surface Mount, resulting in an estimated up to 50% reduction in long-term development time compared to using a proprietary protocol.

Designed and manufactured an experimental prototype of a soil moisture sensor aimed at reducing upfront cost to farmers by up to 70%. Built an accompanying Android app for data retrieval. Prototype was evaluated in a controlled laboratory environment to gain insights into its accuracy and potential.

Findings were published and presented at EuroSensors2018 conference.
