I'm a full-stack engineer—I've worked on computers at every level from hardware design to JavaScript frontends, and have an in-depth understanding of computing that allows me to pick up new technologies at a rapid clip. Some of the things I've build live deep within the guts of websites or aren't public, but here are a few you can see out in the wild.
I also have a few small projects available on Github, mostly on Android at present.
What's that obscure mass of letters and numbers? 8260CSFB is the part number of a system-on-a-chip (SoC), or a whole computer on a single chip. It was the first Qualcomm GSM chipset to use a 4G LTE modem, which was a separate chip that talked to the main one and drew more power, so it took a lot of work to get power management under Android into a good state. Getting Android working right required making a whole ton of builds using Git, repo, and GCC; lots of code review via Gerrit, and huge amounts of debugging using tools like a Trace32 JTAG (to debug right on the the chip), a Spartan power-testing tool to view the power used by individual power rails on the chip, and writing custom Android test apps.
A big result was the HTC Vivid, the first LTE phone on AT&T, reviewed by Engadget as having "excellent standby power management"—precisely the feature I ensured was working at its highest.
