For Pebblebee, Luma. Wrote the entire firmware from scratch for several shipping products. Helping with hardware engineering in addition to software engineering for the company's latest products in development.Senior embedded developer, including device-side applications, firmware, and processor bootstrap. Bluetooth low energy; Bluetooth Smart; Cellular (GSM, LTE); Narrowband (LTE CAT M1, LTE CAT NB1); Wi-Fi.Custom algorithms on device-side, client-side for iOS, Android, OS X, and Windows (for example custom Kalman filter from scratch implemented in C, Swift, and Java). Custom test apps. Occasional custom C Standard Library implementations (for fun).I also verify schematic and layout against reference designs for each hardware iteration. I test for and correct failures for both software and hardware. For each round of hardware development I work directly with partners to make necessary changes in the design before they spin new boards.I can ship a hardware product on any internal platform. Doesn't even need a kernel. Only have 4 kilobytes of storage? Only have 1.5 kilobytes of RAM? Only have a battery so small that you need to drive the entire bootstrap with just the AWU to minimize current consumption? Then you've come to the right place!Working with a new technology that has barely been standardized, the only implementation of which is so new and buggy with freshly printed preview silicon that you need someone in the wild to find the one branching path that somehow succeeds? Also the right place then!
