Summary
👤
Senior🎓
Top SchoolEric Poulsen is a Senior Firmware Engineer with 12+ years building embedded systems, firmware, and IoT solutions across ESP32, AVR, Raspberry Pi and ARM platforms, and a strong background in C, C++, Python and MicroPython. He blends low-level driver work (HW SPI, I²C, UART, watchdogs) with advanced Linux administration, board-level prototyping and AWS cloud integrations, enabling end-to-end device-to-cloud products. Notable open-source contributions include significant enhancements to the widely used MicroPython project—adding non-blocking SSL, wired Ethernet, RTC, sleep modes and ESP32 peripheral support. Eric’s experience spans startups and enterprises (Syntiant, Arista, Shure) and roles from hardware architect to embedded lead, giving him a rare cross-domain fluency in circuit design, firmware and cloud services. Based in Aliso Viejo, CA, he’s currently focused on firmware and neural-network driver work, bringing pragmatic problem-solving honed since hands-on Navy technical training.

Mar 2017 - Oct 2017
Old port of MicroPython to the ESP32 -- new port is at https://github.com/micropython/micropython
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:17 commits, 31 PRs, 399 comments in 7 months
Contributions summary:Eric primarily contributed to the MicroPython port for the ESP32. They implemented hardware SPI peripheral support, including initialization and data transfer capabilities. They also added a `unique_id()` function to access the MAC address and implemented a `WDT()` class for the watchdog timer. Furthermore, the user addressed socket-related issues and improved the Ethernet interface functionality.

MicroPython - a lean and efficient Python implementation for microcontrollers and constrained systems
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:17 commits, 12 PRs, 181 comments in 2 years 3 months
Contributions summary:Eric focused on enhancing the MicroPython environment for embedded systems. Their contributions involved implementing non-blocking SSL sockets, adding a `getpeercert()` method for SSL sockets, and incorporating finalizer support to manage ussl object memory. They also integrated wired Ethernet functionality by implementing `network.LAN()`, alongside adding features like sleep/deepsleep capabilities and an RTC class to the machine module. Additionally, the user fixed issues and improved functionalities related to HW SPI transfers and DNS configuration in the network module.
